Where the programs split
Lenders think about small multifamily in two ways. Some see a residential property with several tenants and underwrite it like a single-family rental with more rent. Others see a small business and want the loan structured as commercial or DSCR financing. The digital program's eligible property types are set by its guidelines and change over time; bank and portfolio programs each publish their own list. We check the current list for the property in front of us rather than promising a category on a web page, and the answer is usually clear within a day.
Documenting rent from several units
Each unit's lease and payment history can support the file. On a bank-statement application the deposits show the rent arriving; on a full-doc file the leases and your Schedule E show it. Vacant units count for nothing, so a building with one vacant unit of four is documented as three streams of rent, and the lender's view of the property follows. Keep leases current and signed; month-to-month tenants with no written lease are a frequent snag.
Valuation
Automated valuations are built on single-family comparable sales and are least reliable on multi-unit property, where the income matters as much as the square footage. Expect the lender to want an appraisal more often on a 2–4 unit building than on a house, which adds time and cost. An appraisal on multi-unit property includes a rent schedule, which also feeds the income side of the file.
If you live in one of the units
An owner-occupied duplex is a primary residence, not an investment property, and it qualifies for primary-residence lines with their wider limits and wider lender list. If you live there, say so; it is the better side of the fence to be on. If you moved out and now rent all the units, the property is investment property from the lender's point of view regardless of how long you lived there, and the rental-property rules apply.
What to have ready
- Leases for every occupied unit, and the rent roll
- The first-mortgage statement and any other liens
- How title is held — your name, a trust, or an LLC (see the LLC page)
- The landlord insurance policy
- Whether any unit is a short-term rental, which some programs treat differently
Questions investors ask about this
Can I get a HELOC on a fourplex?
On some programs, yes. Two-to-four-unit property is residential, but each program decides whether it includes small multifamily and how. We confirm the current rule for your building before you apply rather than promising it here.
Does a duplex I live in count as an investment property?
No. If you occupy a unit it is your primary residence, and it qualifies for primary-residence lines with wider limits. A duplex you moved out of and fully rent is investment property.
How is rent from multiple units documented?
A lease and payment history per unit — visible in bank deposits on a bank-statement file, or through leases and Schedule E on a full-doc file. Vacant units count as no rent.
Will I need an appraisal?
More likely than on a single-family rental, because automated valuations are weakest on multi-unit property. The appraisal includes a rent schedule that also supports the income side.
What about five or more units?
That is commercial property and outside every program here. A commercial line or a small-balance commercial loan is the product for it.
