San Jose's 2-4 unit buildings are mostly mid-century: stucco fourplexes from the 1960s near San Jose State, side-by-side duplexes in Berryessa and East San Jose, and older homes downtown split into two or three units. They rent well because they are close to jobs, transit and the university, and they trade in a different price band than single-family homes nearby.
In short: LendingStreet offers DSCR loans for San Jose duplexes, triplexes and fourplexes that qualify on the combined rent of all units, with no W-2s or tax returns and LLC borrowers standard. Loans start at $150,000 with no stated maximum and purchases go up to 80% LTV on some programs. Because many San Jose triplexes and fourplexes fall under the city's Apartment Rent Ordinance, in-place rents and realistic leverage matter more here than the program maximum.
Fourplexes and triplexes cluster around San Jose State and downtown, in the Naglee Park and Spartan Keyes areas, around Japantown and the Burbank neighborhood, and along older corridors in Santa Clara and Campbell. Duplexes are common in Berryessa, East San Jose, Willow Glen's edges and parts of Cambrian.
Many of these buildings have separate meters and simple layouts, which keeps operating costs predictable. Others are converted older homes, where the legal unit count needs checking.
Tenant demand comes from several directions at once: students and staff at San Jose State, workers at downtown offices and the airport, hospital staff, and households priced out of buying. That mix keeps vacancy short in well-run buildings, though rents vary block by block, so get a rent survey for the specific street.
San Jose's two-family zoning allows duplexes in many neighborhoods, and multiple-residence districts allow more. State law has widened options: ADUs and junior ADUs can be added to many lots, and SB 9 allows some single-family lots to be split or to hold two units. Fourplexes on R-1 lots are not automatic, so confirm what the parcel allows with the city's planning department.
For a DSCR loan, only legal units count. A building sold as a triplex that is legally a duplex with an unpermitted garage unit will usually be underwritten as a duplex.
San Jose's Apartment Rent Ordinance generally covers buildings with three or more units first occupied before late 1979, limiting annual increases for existing tenants. Duplexes are generally outside the ARO but can fall under statewide rent cap and just-cause rules, and the city has additional tenant protection rules. Confirm a building's status with the city's Rent Stabilization Program.
For underwriting, occupied units count at their lease rent. A fourplex with three long-term tenants below market and one recently turned unit is typical, and the loan is sized on that real rent roll, not on what the units could rent for.
This example is illustrative and not a quote. An investor buys a 1960s fourplex for $1,850,000. Each two-bedroom unit rents for about $2,600, for combined rent of $10,400 a month. Taxes are estimated at about 1.2% of the purchase price, or $1,850 a month, and insurance at $400 a month.
At 60% of the price, the loan is $1,110,000 and estimated principal and interest is about $7,572 a month. The total with taxes and insurance is about $9,822, giving a DSCR of about 1.06x. At 70% the same building would fall below 1.0x, which is why most San Jose fourplexes close somewhere near 55% to 65% LTV.
| Item | Amount |
|---|---|
| Purchase price | $1,850,000 |
| Loan amount (60%) | $1,110,000 |
| Combined monthly rent | $10,400 |
| Estimated principal and interest | $7,572 |
| Property taxes (monthly) | $1,850 |
| Insurance (monthly) | $400 |
| Total monthly payment | $9,822 |
| DSCR | 1.06x |
Property is reassessed at purchase, so a buyer's tax bill starts at roughly 1% of the price plus local voter-approved charges, which in parts of San Jose push the total above 1.2%. Santa Clara County charges a documentary transfer tax, and San Jose added a city transfer tax on higher-priced sales, starting around $2 million. Who pays is negotiated in the contract.
Insurance is generally available for South Bay apartments, but older buildings with original wiring, plumbing or roofs can cost more to insure. Ask for quotes early.
Some older buildings also have deferred maintenance that a property inspection will surface: foundation cracks, galvanized plumbing, flat roofs near the end of their life. Those costs do not change the DSCR formula, but they change your cash needs in the first few years and should shape your offer.
Buyers include engineers adding a first income property, long-time owners trading a high-value house for a building with more units, and investors who buy older fourplexes to update units as tenants move out. Our loans are for investors only. We do not finance a building where the borrower lives in one of the units.
If you are looking at a five- or six-unit building, it is still residential for our programs, though maximum LTV can be lower, varies by program. See our San Jose 5-8 unit page. Buildings of nine or more units belong on our multifamily page.
Owners of several duplexes or fourplexes sometimes combine five or more of them under a single blanket loan once the portfolio grows, which can simplify payments and refinancing.

Generally not, but statewide rent cap and just-cause rules may apply. Confirm the specific building's status with the city.
A permitted ADU can count toward rent. Unpermitted units are usually excluded.
Programs allow up to 80% LTV on purchases, but many San Jose fourplexes reach 1.0x around 55% to 65%.
