Duplex to mixed-use: unit count changes the loan in LA and the IE

Why the unit count matters so much

A lender’s program guide is organized by property type first and borrower second. One-to-four units sit in the residential world: standard appraisal forms, comparable sales, and a rent schedule the underwriter can read quickly. Five units and above sit in the commercial world: income capitalization, rent rolls, expense statements and a different set of lenders entirely.

For an investor, that boundary is not a technicality. Crossing it changes the appraisal method, the documentation, the loan size range and often the prepayment structure. A fourplex and a five-unit building next door to each other in Los Angeles can be financed by completely different institutions.

Duplex, triplex, fourplex

These are the workhorses of LA and Inland Empire rental investing, and they fit DSCR programs comfortably. The ratio is calculated on the combined rent from all units, which usually helps: a duplex with one strong unit and one average unit often covers better than a single-family home at the same price.

In the City of Los Angeles, an older duplex or fourplex may be covered by the RSO, which changes the rent growth a lender will assume. The documentation is a rent roll, leases for each unit, and an appraisal that supports market rent for each — with the RSO registration and rent history included where they apply.

Five units and above

At five units the file becomes a commercial loan. The lender will want operating statements, a rent roll with lease expiration dates, a schedule of expenses, and a valuation that leans on the property’s income rather than on nearby home sales. The ratio still matters, but it is usually calculated with a vacancy factor and a reserve for replacements.

Loan sizes are larger, lender relationships are fewer, and the process takes longer. For an investor moving from houses to a small LA or Inland Empire apartment building, the most useful preparation is clean books: two years of operating statements and a realistic expense history.

Clean operating statements do more for a five-plus unit file than any single negotiating point.

Mixed-use properties

A building with apartments over a storefront is a Southern California staple, especially in older commercial corridors. Lenders generally treat it as commercial if the commercial portion is more than a modest share of the space, and some will not lend on it at all.

The issues are specific: the lease terms on the commercial unit, the tenant’s business and credit, the allocation of space, zoning and any conditional use permit, and whether the residential units are legal. A mixed-use file fits a lender who knows the asset class and frustrates one who does not.

• Lease for the commercial tenant, including remaining term and options
• Zoning and any conditional use permit for the property
• Allocation of square footage between residential and commercial
• Evidence that the residential units are legally permitted
• Insurance that covers both uses

Condominiums, townhomes and ADUs

A condo unit is only as financeable as its project, and LA and the Inland Empire have plenty of projects with high rental concentration or deferred maintenance that narrow the field. The HOA questionnaire is the document that reveals whether a project is acceptable before you pay for an appraisal.

An accessory dwelling unit can transform a single-family file. Whether the lender counts the income depends on the unit being permitted, on the appraisal supporting a rent figure for it, and on the program’s treatment of two-unit income on a single parcel. An unpermitted conversion is usually excluded entirely.
