Selling a Fourplex or Small Apartment Building in Los Angeles
Q4 2026
Key Takeaways
Buildings with two to four units sell differently from larger apartment buildings. The buyers, the financing, and the way the price is set are all different.
Many small-building buyers are owner-occupants or smaller investors who finance with a residential loan, while buildings with five or more units are financed with commercial loans and valued mostly on income.
Accurate rents, organized records, and a clear picture of the building’s condition matter just as much in a small sale as in a large one.
Who Buys a Fourplex
Fourplexes and other two-to-four-unit buildings attract two main kinds of buyers. Owner-occupants live in one unit and rent out the rest, which can let them put less money down than an investor would. Smaller investors, including owners exchanging out of other property, buy for the income and the long-term appreciation.
Because the buyer pool includes people who want the property as a place to live, small buildings can sometimes sell for more than their income alone would support.
How Financing Differs
In general, buildings with up to four units can be financed with residential mortgages, while buildings with five or more units need commercial loans. A residential loan leans heavily on the buyer’s income and credit, and the property’s own income plays a smaller role. A commercial loan looks hard at the building’s net operating income and cap rate.
That difference changes who can buy your building and how a lender’s appraisal will treat it, so it is worth knowing which side of the line your building falls on.
How the Price Is Set
Small buildings are usually priced by comparing recent sales of similar buildings nearby, using price per unit, price per square foot, and the gross rent multiplier, which is the price divided by the yearly rent. Larger buildings lean more on net operating income and cap rate.
For a fourplex, the most useful comparables are other small buildings in the same neighborhood, not large apartment complexes. A Broker Opinion of Value built on those comparables and your own rents is the most reliable way to set a price, and our article on how buyers value an apartment building explains the main measures.
Rent Control Still Applies
Being small does not take a building out of the rent rules. In the City of Los Angeles, the Rent Stabilization Ordinance generally covers multi-unit buildings with a certificate of occupancy issued before October 1, 1978, including smaller ones, and newer buildings typically fall under the statewide AB 1482 cap unless they are exempt. Our articles on selling with rent-controlled tenants and the 2026 AB 1482 rent cap explain how those rules affect price.
Preparing a Small Building for Sale
With only a few units, each one matters. A single vacant unit, or one tenant paying far below market, can change the numbers noticeably. Buyers will look closely at the unit mix, the condition of the roof, plumbing, and electrical, and the age of the major systems.
Fixing small issues first, confirming your rents and lease terms, and organizing your leases and expense records keep the sale moving. The same steps apply as in a larger sale, which we lay out in our guide to the step-by-step process of selling an LA apartment building.

Frequently Asked Questions
Who buys a fourplex, and can I sell it to someone who wants to live in one unit?
Two main kinds of buyers: owner-occupants, who live in one unit and rent out the rest, which can let them put less money down than an investor would, and smaller investors, including owners exchanging out of other property. Because the pool includes people who want a place to live, small buildings can sometimes sell for more than their income alone would support.
How do buyers get a loan for a fourplex compared with a bigger apartment building?
In general, buildings with up to four units can be financed with residential mortgages, while buildings with five or more units need commercial loans. A residential loan leans heavily on the buyer’s income and credit, while a commercial loan looks hard at the building’s net operating income and cap rate.
How do I figure out what my fourplex is worth?
Usually by comparing recent sales of similar small buildings nearby, using price per unit, price per square foot, and the gross rent multiplier, which is the price divided by the yearly rent. Larger buildings lean more on net operating income and cap rate. A Broker Opinion of Value built on those comparables and your own rents is the most reliable way to set a price.

Yes. In the City of Los Angeles, the Rent Stabilization Ordinance generally covers multi-unit buildings with a certificate of occupancy issued before October 1, 1978, including smaller ones, and newer buildings typically fall under the statewide AB 1482 cap unless they are exempt.
How do I get my fourplex ready to sell?
