Can you get a HELOC on a duplex, triplex or fourplex?
Duplexes and three- to four-unit properties are eligible. Most home equity lenders stop at a single unit, or at two. This line reaches four, whether you live in one of the units or rent all of them out — with a higher credit floor of 680 if the building is an investment property.
These are the requirements for the home equity line we place. Other lenders set their own guidelines, and some are more flexible.
The small multi-unit building — a duplex in Long Beach, a fourplex in Koreatown, a Victorian cut into three flats in the Mission — is the property type most often turned away from home equity lending, usually for no better reason than the lender’s box stops at one unit. If you own one, you have likely been told no at least once.
Here the box goes to four. The rest of this page is what changes when it does.
Owner-occupied or investment
If you live in one of the units, the property is your primary residence and the standard credit minimum of 640 applies. If you don’t, it is an investment property: the minimum rises to 680.
If the building is held in an LLC, the LLC rules apply: a minimum 25% ownership, a credit floor of 700 for an investment property, and a combined loan-to-value cap of 70%.
How a small multi-unit building is valued
The valuation starts with an automated model, as it does for a house. Small multi-unit buildings are harder for a model to price — fewer comparable sales, more variation in unit mix and condition — so a desktop appraisal is a more common second step here than on a tract home. That is normal, not a problem; it is the standard path for a property the model can’t settle.
What does matter is unit count of record. A duplex that has been quietly converted into a triplex is valued as the duplex that is recorded, and the unpermitted unit can introduce a condition question. Know what the county has on file before you apply.
Five units is the line
Five or more units is a commercial property under residential lending rules and is not eligible here. If you own a fourplex with a fifth unit added without permits, it is a fourplex of record — but see the section above. If you own a five-unit building that is legally five units, this is not the product for it.
Where the 2–4 unit stock is
Los Angeles County has roughly 32,000 owner-occupied 2–4 unit properties, concentrated in the older neighborhoods of the central city, Long Beach, Pasadena and the San Gabriel Valley. San Francisco is the outlier in the state: 17.4% of its owner-occupied homes are in 2–4 unit buildings, about 24,000 properties, and Oakland and Berkeley carry the same pattern. Orange County has fewer, mostly in Costa Mesa, Anaheim and Huntington Beach.

Duplexes, Triplexes and Fourplexes: questions
A duplex, triplex or fourplex is valued with a residential evaluation by a local professional rather than an automated model, which adds a few days. Debt-to-income on a 2–4 unit property is capped at 45% instead of 50%.
Yes. Duplexes and 3–4 unit properties are eligible property types for the home equity line we place. If you live in one unit it is treated as your primary residence; if not, it is an investment property with a 680 credit minimum.
Yes, as an investment property. The credit minimum is 680, or 700 if the building is owned through an LLC, and scores below 640 are not eligible on an investment property.
Not eligible. Five or more units is a commercial property under residential lending rules. The line stops at four units of record.
Not necessarily. The valuation starts with an automated model and moves to a desktop appraisal when the model can’t settle the value, which is more common for small multi-unit buildings than for tract homes. Either path is routine.
These are the requirements for the home equity line we place. Other lenders set their own guidelines, and some are more flexible.
