In 2026, buying an entry-level duplex with an FHA loan at 3.5 percent down and renting the other unit costs less each month than renting a comparable apartment across a set of mid-priced U.S. metros. Effective housing cost is the full monthly payment, meaning principal, interest, taxes, insurance and FHA mortgage insurance, minus the rent collected from the other unit, with an allowance for maintenance and vacancy already taken out of that rent. In Cleveland it lands near $821 a month against $1,154 to rent. It does not work in expensive coastal markets.
You can probably own for less per month than you’re paying to rent.
That’s true today, not ten years from now. In a lot of affordable cities, buying a small duplex and renting out the other half costs you less every month than renting a comparable place. Here are the numbers, with every assumption shown.
How the duplex math works
Effective housing cost is defined as the total monthly mortgage payment (principal, interest, taxes and insurance) minus the rent collected from the other unit of a two-unit property. When that figure falls at or below the local rent for a comparable place, owning the whole building costs less each month than renting one unit of it.
Principal + Interest + Taxes + Insurance − Rent from unit 2 = Effective housing cost
Worked example: Cleveland, Ohio, 2026 screen
| Renting a comparable place | $1,154 |
| Owning the duplex, all in, after the tenant’s rent | $821 |
| Kept every month by owning | $333 |
Cleveland ranked fourth on the 2026 screen. The all-in figure already carries taxes, insurance, FHA mortgage insurance and an allowance for maintenance and vacancy taken out of the rent collected, on an entry price near $169,997. These are model outputs, not a quote. The full Cleveland report has the line items, the local risks and the sources.
What this is not
- It’s not free money or a get-rich thing. It’s getting your housing cost down to near-nothing so you can finally save. The same move I used to climb out.
- You do need cash to get in: about 3.5% down plus closing costs. Down-payment assistance can cut that a lot, and the roadmap shows you where to find it.
- With an FHA loan you have to live in the property for at least the first year. You’ll be a landlord living next to a tenant, a real trade-off, just not a dollar one.
- It doesn’t work in expensive markets or at every price. Where duplexes are pricey (much of the coasts), the math flips. This is a Midwest / Rust Belt / South play.
- The numbers already include a repair-and-vacancy cushion, so they’re conservative on purpose. Your real deal could be better or worse, run your own.

You don’t need rich parents or 20% down. You need a plan that starts from your real situation, debt, low savings, all of it, and sequences the climb. That’s the free roadmap.
House hacking questions people ask
Can owning a home really cost less per month than renting?
Yes, in a number of affordable U.S. metros. Effective housing cost is defined as the full monthly payment minus the rent from the other unit. Buying a modest duplex with an FHA 3.5%-down loan, living in one unit, and renting the other produces an effective monthly housing cost lower than the local one-bedroom rent, in Cleveland roughly $821 per month versus $1,154 rent on the 2026 screen, all assumptions published above. It does not work in expensive coastal metros.
How much money do you need to buy a duplex with an FHA loan?
The minimum cash to buy a duplex with an FHA loan is defined as 3.5% of the purchase price plus closing costs. FHA requires that 3.5% down on 1-4 unit owner-occupied properties. On a $150,000 duplex that is $5,250 down plus roughly 2-3% in closing costs, and county down-payment-assistance programs can cover part of it. The buyer must live in the property for at least the first year.
What is effective housing cost?
Effective housing cost is defined as your total monthly payment (principal, interest, taxes, insurance and FHA mortgage insurance) minus the rent you collect from the other unit, plus a repair-and-vacancy reserve. It is the straight number an owner-occupant actually pays to live, and the right number to compare against rent.
Which cities does this work in?
The 2026 screen ranks eleven metros, and eight of those leave an owner ahead of renting month to month. The current roster, with entry prices and the amount kept, is on the duplex markets page. It is re-screened when the data refreshes, which is why the list lives there rather than here.
