Should I Rent or Sell My San Diego Home? A 2026 Decision Guide for Homeowners

Quick Answer

Should I rent or sell my San Diego home in 2026? The decision turns primarily on four property- and owner-specific variables rather than simply on whether the San Diego market is rising or falling: whether the federal capital gains exclusion is currently available, what the property will actually rent for at its bedroom count, what the mortgage rate on the existing loan is relative to replacement financing, and how far the Proposition 13 assessed value sits below market. Selling tends to win when a large gain is currently excludable and there is no plan to re-occupy. Holding tends to win when the existing mortgage rate is well below current rates and the assessed value is far below market.

What does a San Diego house rent for in 2026? Three-bedroom average market rent ranges from $4,140 in ZIP 92104 to $6,880 in ZIP 92024 across the eight ZIP codes reviewed here. Four-bedroom ranges from $4,580 to $7,420. Source: RentCast ZIP-level rental market reports pulled August 24, 2026.

How long do I have to sell before I lose the capital gains exclusion? Under IRC section 121 the property must have been your principal residence for at least 2 of the 5 years ending on the date of sale. Renting it out does not void the exclusion immediately, but the 5-year window keeps running, so for an owner who had already satisfied the ownership-and-use test at move-out, the sale generally has to close within roughly three years of moving out. Other section 121 conditions apply. Depreciation claimed during the rental period is separately recaptured and cannot be excluded.

What is the San Diego home sale market in 2026? The detached median sale price is $1,150,000, up 4.6% year over year, with months of supply down 26.5% for detached homes. Attached is $659,000, up 1.4%. Source: Greater San Diego Association of REALTORS, San Diego MLS data, current as of August 5, 2026.

Does AB 1482 apply if I rent out my house? The rent cap exemption for new construction runs on a rolling 15-year window from the certificate of occupancy date, not a fixed year, and the window advances every January. A separately alienable single-family home or condominium can also be exempt, but only where the owner is not a corporation, REIT, or LLC with a corporate member, and only where the statutory exemption notice is in the rental agreement. Without that notice the cap applies at 8.2% for August 1, 2026 through July 31, 2027.

2026 San Diego Rent vs. Sell Data: Key Findings

Across eight San Diego County ZIP codes reviewed August 24, 2026: average three-bedroom rent ranged from $4,140 to $6,880 per month; average four-bedroom rent ranged from $4,580 to $7,420 per month; and average three-bedroom rent exceeded the all-unit ZIP average by $580 to $2,050 per month. The San Diego County detached median sale price was $1,150,000, up 4.6% year over year, as of August 2026. The Freddie Mac 30-year fixed-rate survey average was 6.65% on August 20, 2026. ZIP codes reviewed: 92009, 92024, 92054, 92104, 92117, 92126, 92128, 92131. Rent figures: RentCast. Sale price: Greater San Diego Association of REALTORS, San Diego MLS.

The gap tracks the composition of the ZIP's rental stock, not the desirability of the neighborhood. North Park shows a $1,530 monthly gap because 95% of its 510 active listings are studios, one-bedrooms, or two-bedrooms. Carlsbad shows only $580 because its listing pool already skews toward larger units.

That is why the gap has to be measured per ZIP rather than estimated. In 92104 the difference between the two benchmarks is more than $18,000 a year, which on its own is enough to change how a marginal hold decision looks.

Get the rent number before you run the decision

We benchmark your property against live comparables at its bedroom count, confirm whether it is AB 1482 covered or exempt, and give you the number in writing. Free, no obligation.

Rent versus sell is determined primarily by four property- and owner-specific variables that run on independent clocks: the capital gains exclusion, the achievable rent against carrying cost, the existing mortgage rate against replacement financing, and the Proposition 13 assessed value against market. Each has to be quantified separately, and none of the four is answered by a view on where the market is heading.

Variable 1, the capital gains exclusion. Under IRC section 121 a married couple filing jointly may exclude up to $500,000 of gain, a single filer up to $250,000, provided the property was their principal residence for at least 2 of the 5 years ending on the sale date. This is the only one of the four that expires, and the clock starts the day you move out. Other section 121 conditions apply beyond the ownership-and-use test.

Variable 2, cash flow. Achievable rent at the property's bedroom count, minus principal and interest, property tax at the current assessed value, landlord insurance, a maintenance reserve, management, and HOA where applicable. On a property bought recently at current prices this is deeply negative. On a property bought a decade ago it is often positive. The two cases are modeled below.

Variable 3, the existing mortgage rate. A below-market mortgage rate creates a recurring financing advantage, and that advantage is not portable. Selling extinguishes it. On two illustrative $700,000 30-year loans, the payment difference between 3.0% and 6.65% is $1,543 a month, or $18,510 annually. An owner's actual financing advantage depends on the remaining balance and term of the existing loan and on the financing that would replace it.

Variable 4, the Proposition 13 assessed value. Article XIII A caps annual increases in assessed value at 2%. Over a long hold, 2% annual compounding can move the assessed value substantially, so the benefit should be calculated from the current assessment rather than inferred from the original purchase price. It is measured below rather than asserted.

A point most published guidance gets wrong. Section 121(b)(5) reduces the exclusion for periods of nonqualified use, and this is frequently described as meaning that renting your former home causes part of the gain to become taxable on a pro rata basis.

That is not what the provision says. Section 121(b)(5)(C)(ii)(I) expressly excludes from nonqualified use any portion of the 5-year period that falls after the last date the property was used as the principal residence. For an owner who otherwise qualifies for the exclusion, renting the property after moving out does not itself create nonqualified use, and the exclusion is not prorated for it. The critical timing issue is whether the ownership-and-use test can still be satisfied on the sale date. This distinction is worth several tens of thousands of dollars and it is commonly misstated.

The spread between the two profiles is $4,232 a month, and none of it comes from the property. It comes entirely from the loan and the assessed value. This is why generic rent-versus-sell advice fails: the same house, in the same ZIP, at the same rent, can produce strongly positive holding economics for one owner and strongly negative holding economics for another. Cash flow alone does not settle the decision, because the capital gains position can still point the other way.

Worked example. A home purchased in 2005 for $650,000 and held to 2026, with the maximum 2% increase applied every year, carries an assessed value of approximately $985,000. Not $650,000. The base has risen 52% under the cap.

At an all-in rate of 1.15%, that assessment produces roughly $11,330 a year in property tax. If the property were sold at the countywide detached median of $1,150,000, the buyer's assessment resets to that price and the tax becomes roughly $13,225 a year.

The difference is about $1,895 a year, or $158 a month. Real, worth keeping, and roughly one tenth the annual value of a 3% mortgage on a $700,000 balance.

The following is a constructed illustration built from the rules described above, not a client file or a description of any actual property or owner. It shows how a sequence of individually reasonable decisions produces a large tax event.

Setup. Married couple, filing jointly. Home purchased for $520,000. Occupied as principal residence for more than two years, then vacated on relocation. Value at the time of the move, $820,000. Gain at that point, $300,000, fully inside the $500,000 exclusion. Federal and California income tax on the $300,000 gain if sold then: $0, assuming full section 121 eligibility.

Decision. Rent rather than sell. Reasonable on its face. Cash flow is positive, the property is appreciating, and nothing has been forfeited yet.

Years one through three. Depreciation runs on the improvement portion of basis. Assuming land is 30% of the purchase price, the depreciable base is $364,000 and the annual deduction is $13,236. Nothing is lost, because a sale inside three years still qualifies.

Year four. The couple decides not to return. The 2-of-5-year test can no longer be met without re-occupying for two full years. The full exclusion is no longer available under the standard 2-of-5-year test without re-establishing qualifying use.

Year six, sale at $1,050,000. Depreciation taken over six years totals $79,418. Adjusted basis is $440,582. Total gain is $609,418. Of that, $79,418 is unrecaptured section 1250 gain taxed at up to 25%, which is $19,855. The remaining $530,000 is long-term capital gain with no exclusion available, roughly $196,630 at an illustrative combined top-rate assumption of 37.1%.

Using the deliberately simplified facts and the upper-bound top-rate assumptions above, the illustrative tax calculation is approximately $216,500, compared with $0 of federal and California capital-gains tax on the $300,000 gain if the property had been sold while the full section 121 exclusion remained available. The rental period generated income and appreciation, and the modeled tax event consumed a substantial share of both.

AB 1482, and the exemption that is not a fixed year. The new construction exemption under Civil Code section 1947.12(d)(4) applies to housing issued a certificate of occupancy within the previous 15 years. It is a rolling window that advances every January, not a fixed cutoff date, and any source stating a fixed year is describing a window that has since moved. A separately alienable single-family home or condominium may also be exempt under section 1947.12(d)(5), but only where the owner is not a real estate investment trust, a corporation, or an LLC with a corporate member, and only where the statutory exemption notice appears in the rental agreement for tenancies commenced or renewed on or after July 1, 2020. Where the cap applies it is 8.2% for increases effective August 1, 2026 through July 31, 2027, which is 5% plus 3.2% CPI using the BLS San Diego-Carlsbad twelve-month change ending March 2026. See the AB 1482 exemption guide.

Just cause attaches at 12 months under state law. Civil Code section 1946.2 requires just cause once the tenant has continuously occupied the unit for 12 months. Day-one just cause is a local rule, not a state one. Within the City of San Diego, SDMC sections 98.0701 through 98.0709 impose just cause from the start of the tenancy, along with relocation assistance for no-fault terminations and notice to the San Diego Housing Commission. Which rule applies is decided by the parcel, not the mailing address. See which San Diego cities have local ordinances.

AB 12, security deposit. For most California residential landlords the maximum is one month's rent, furnished or unfurnished, under Civil Code section 1950.5. A narrow exception permits up to two months for a natural person, or an LLC whose members are all natural persons, owning no more than two residential rental properties totaling no more than four dwelling units, and that exception does not apply where the prospective tenant is an active-duty servicemember. Return within 21 days with an itemized statement. See the security deposit guide.

AB 2801 photographs, on two separate dates. Since April 1, 2025, photographs are required immediately after the tenancy ends and before any cleaning or repairs, plus photographs after repairs where a deduction is claimed, and that applies to all tenancies regardless of start date. Since July 1, 2025, move-in photographs are also required, but only for tenancies beginning on or after that date. A converting homeowner starting a new tenancy today falls under both. The move-in set cannot be reconstructed later.

AB 2493 screening, and AB 2747 rent reporting. Written screening criteria must be provided to applicants and disclosed before any screening fee is collected, applications considered in the order received, the fee limited to the actual out-of-pocket cost of gathering information, and a copy of any credit report provided within 7 days. Separately, tenants must be offered the option to have rent payments reported to credit bureaus, at signing and annually. See the 2026 California rental laws overview.

AB 628, appliances. For leases signed, renewed, or amended on or after January 1, 2026, a working stove and refrigerator are habitability requirements under Civil Code section 1941.1.

Should I rent or sell my San Diego home in 2026?

It depends primarily on four property- and owner-specific variables rather than simply on whether the market is rising or falling. Selling tends to be better where a large gain is currently excludable under IRC section 121, there is no plan to re-occupy, and the existing mortgage is already near current market rates. Holding tends to be better where the existing rate is well below current rates, the Proposition 13 assessed value is far below market, and the property rents at or above carrying cost. The same house produces opposite answers for two different owners, so the calculation has to be run on your own loan balance, rate, assessed value, and bedroom-count rent.

What does a San Diego single-family home rent for in 2026?

Three-bedroom average market rent runs from $4,140 in ZIP 92104 to $6,880 in ZIP 92024 across the eight San Diego County ZIP codes reviewed here. Four-bedroom runs from $4,580 to $7,420. In between: 92126 at $4,230, 92131 at $4,310, 92117 at $4,400, 92054 at $4,610, 92128 at $4,630, and 92009 at $5,010 for three bedrooms. Source: RentCast ZIP-level rental market reports, pulled August 24, 2026.

Why is a countywide median rent the wrong benchmark for a house?

Because it blends houses with studios, one-bedrooms, and apartment inventory. In all eight San Diego County ZIP codes reviewed, the three-bedroom average rent exceeded the all-unit average for the same ZIP, by between $580 and $2,050 a month, which annualizes to between $6,960 and $24,600. The size of the gap tracks the composition of each ZIP's listing pool rather than neighborhood desirability, so it has to be measured per ZIP rather than estimated. Source: RentCast, August 24, 2026.

How long can I rent my house before I lose the capital gains exclusion?

IRC section 121 requires the property to have been your principal residence for at least 2 of the 5 years ending on the date of sale. Because the two qualifying years are behind you when you move out, the sale generally has to close within roughly three years of moving out. Renting during that period does not itself reduce the exclusion. Depreciation claimed during the rental period is separately recaptured under section 121(d)(6) and cannot be excluded. Consult a CPA for your situation.

Does renting my former home make part of the gain taxable under the nonqualified use rule?

No, and this is widely misstated. Section 121(b)(5) reduces the exclusion for periods of nonqualified use, but section 121(b)(5)(C)(ii)(I) expressly excludes from that definition any portion of the 5-year period falling after the last date the property was used as the principal residence. For an owner who otherwise qualifies, renting after moving out therefore does not itself create nonqualified use and does not cause the gain to be prorated. The critical timing issue is whether the ownership-and-use test can still be satisfied on the sale date. The nonqualified use rule generally reaches periods of non-residence occurring before the property became your principal residence.

What is depreciation recapture and can I avoid it by moving back in?

Depreciation recapture is the tax on the portion of gain attributable to depreciation taken during the rental period, treated as unrecaptured section 1250 gain and taxed at a maximum federal rate of 25%. Re-occupying the property does not remove it, because section 121(d)(6) states the exclusion does not apply to gain attributable to depreciation allowed after May 6, 1997. Two points owners miss: only the improvement portion of basis is depreciable, so land value must be excluded, and depreciation is recaptured whether or not it was actually claimed, since the statute applies to depreciation allowed or allowable.

Should I keep my house if I have a 3% mortgage?

A below-market mortgage rate creates a recurring financing advantage, and that advantage is not portable. On two illustrative $700,000 30-year loans, a 3.0% loan costs $2,951 a month in principal and interest against $4,494 at the Freddie Mac 30-year survey average of 6.65% as of August 20, 2026, a difference of $18,510 a year. An owner's actual advantage depends on the remaining balance and term of the existing loan and on what would replace it, so that comparison should be re-run on real loan terms. It is the figure negative cash flow should be measured against. The counterweight is the capital gains exclusion, which expires. An owner with a large excludable gain and no plan to return may still be better off selling inside the window despite the rate.

How much is my Proposition 13 tax basis actually worth?

The value depends on the gap between your current assessed value and the property's market value, because Proposition 13's 2% annual assessment cap compounds over time. A home purchased in 2005 for $650,000 and held to 2026 with the maximum increase each year carries an assessed value near $985,000, a 52% rise over the purchase price. At an illustrative all-in rate of 1.15%, that is roughly $11,330 a year against roughly $13,225 if the parcel were reassessed at the countywide detached median of $1,150,000. The advantage is about $1,895 a year, real but roughly one tenth the annual value of a below-market mortgage rate. Use your own parcel's assessed value and tax rate from your bill rather than these illustrative figures.

Does AB 1482 apply if I rent out my primary residence?

It may. The new construction exemption applies to housing issued a certificate of occupancy within the previous 15 years, which is a rolling window advancing every January rather than a fixed year. A separately alienable single-family home or condominium may be exempt under Civil Code section 1947.12(d)(5), but only where the owner is not a REIT, corporation, or LLC with a corporate member, and only where the statutory exemption notice is in the rental agreement for tenancies commenced or renewed on or after July 1, 2020. Absent an applicable exemption the cap is 8.2% for increases effective August 1, 2026 through July 31, 2027. Note that the rent cap and just cause are two separate statutes with non-identical exemption lists, so both have to be answered separately.

What is the San Diego home sale market in 2026?

The detached median sale price is $1,150,000, up 4.6% year over year, with months of supply for detached homes down 26.5% and days on market down 8.3%. Attached homes are at a median of $659,000, up 1.4%. Source: Greater San Diego Association of REALTORS, San Diego MLS data, current as of August 5, 2026. Those are reported changes over a past period and are not a forecast of what the market will do next.

What if my rental is cash-flow negative every month?

Negative cash flow is a price, not a verdict. Measure it against what it buys: the annual value of a below-market mortgage rate, the annual Proposition 13 differential, and whether the capital gains exclusion is still available. Where the existing loan is already near current market rates, the assessed value is close to market, and the exclusion window is closing, negative cash flow is buying very little and selling is usually the stronger answer. Where the loan is far below market, the reverse holds.

What does property management cost for a San Diego house?

A Realty Management Group review of publicly advertised San Diego County property-management company pricing pages found monthly management rates ranging from 7% to 10% of collected rent, with a separate tenant-placement fee at turnover and, at many companies, an advertised renewal fee. Realty Management Group charges a flat $199 per month for one to three units, or $179 per unit for four to sixteen, with no leasing, renewal, or maintenance markup fees. At the three-bedroom rents in Table 1, a percentage model runs roughly $290 to $688 a month before add-ons. Company-by-company rates are compiled in the San Diego property management fees guide.

Key Takeaways

• In all eight ZIP codes measured, three-bedroom rent exceeded the all-unit ZIP average, by $580 to $2,050 a month. A three-bedroom house benchmarked against the all-unit ZIP average therefore starts below the three-bedroom benchmark in every ZIP measured.
• Three-bedroom average market rent runs $4,140 to $6,880; four-bedroom, $4,580 to $7,420. RentCast, August 24, 2026.
• The capital gains exclusion is the variable with a defined eligibility window tied to the sale date. For an owner who satisfied the ownership-and-use test before moving out, that is roughly three years from move-out under the 2-of-5-year test, subject to the other section 121 conditions.
• Renting after moving out is not nonqualified use under section 121(b)(5)(C)(ii)(I) and does not prorate the exclusion.
• Depreciation recapture survives re-occupancy and applies whether or not depreciation was claimed.
• On two illustrative $700,000 30-year loans, 3.0% versus the 6.65% survey rate is a payment difference of $18,510 a year. Negative cash flow should be measured against the owner's actual financing differential, which depends on remaining balance and term.
• In the illustrative 2005-purchase example modeled here, the Proposition 13 advantage is approximately $1,895 a year. The actual benefit depends on the property's assessed value, current market value, and parcel tax rate.
• The AB 1482 new construction exemption is a rolling 15-year window, not a fixed year, and just cause attaches at 12 months under state law. Day one is a City of San Diego rule.
• As of August 2026, Realty Management Group's internal Rentvine records show a countywide 13-day average time to lease, 39-month average tenant retention, 98.9% occupancy, and 99.4% on-time rent collection across 400+ units.
