Apartment building net proceeds estimator What would I keep if I sold my apartment building?
Type in rough numbers. You'll see an estimated value, your costs, a ballpark tax figure, and what a 1031 exchange could keep working for you. Nothing is sent anywhere unless you ask for the full report.
Your rough estimate
Rough estimate only. Assumes 75% of cost is building, 27.5-year depreciation, 25% recapture, 20% federal capital gains, 3.8% investment-income tax and 9.3% California tax. Your real numbers depend on your tax situation; confirm with your CPA. Heirs and trusts may be treated very differently.

Buyers of small San Diego apartment buildings mostly price them on income. The estimator takes your rents, subtracts a share for expenses to get net operating income, and divides by the cap rate buyers are paying to get a value. San Diego metro buildings averaged about a 4.9% cap rate in mid-2026, and small central buildings often trade a little higher.
What it leaves out
Real buyers also weigh condition, parking, rent upside under AB 1482, and recent sales on your block. Your tax depends on your bracket, past depreciation, improvements and whether the building is held in a trust or was inherited. A building inherited from a parent usually gets a stepped-up basis, which can shrink the tax a lot.
Selling outright vs a 1031 exchange
Selling outright means paying capital gains and depreciation recapture tax now. A 1031 exchange moves the full equity into another investment property and defers that tax. The difference between the last two lines above is roughly what a 1031 keeps working for you.
