Lenders don't hold a duplex back from first-time buyers. The same loan programs that finance a starter house for someone who has never owned also finance a two-unit building where one unit is your home. The loan limit for two units is higher too: $693,050 on FHA in most Florida counties for 2026, and $1,066,250 on a Conventional loan. Look up your county with the loan limits tool.
What first-time duplex buyers ask most
Never been a landlord. FHA doesn't require landlord experience on a duplex you live in. The lender counts 75% of the lower of the appraiser's market rent or the signed lease, and the other 25% allows for vacancies and repairs.
Moving in. At least one borrower moves into a unit within 60 days of closing and lives there for at least a year. After that, you can move out and rent both units with the loan still in place.
Cash. FHA's 3.5% down can be a gift from family, and the seller can pay closing costs up to 6% of the price. FHA sets no reserve minimum on a duplex with an automated approval. Conventional takes 5% down on two units, and Conventional and VA want six months of the full payment in the bank after closing.
Scores. FHA goes to 580 for 3.5% down. Conventional starts at 620. VA sets no minimum score of its own, and AAA Capital Funding does VA loans from 500.
A worked example: a $395,000 duplex
Nadia, a first-time buyer, earns $5,400 a month and has a $250 car payment. The duplex is $395,000, and the other unit rents for $1,850. She buys with FHA at a 5.75% rate on a 30-year fixed, with taxes at about 0.90% of the price a year and $380 a month for insurance on two units.
- Down payment (3.5%): $13,825
- Base loan (96.5%): $381,175
- Upfront MIP (1.75%, added to the loan): $6,670.56
- Total loan: $387,845.56
| Monthly payment piece | Amount |
|---|---|
| Principal and interest | $2,263.36 |
| Annual MIP (0.55% of $381,175, divided by 12) | $174.71 |
| Property taxes | $296.25 |
| Insurance | $380.00 |
| Total housing payment | $3,114.32 |
The lender adds 75% of the rent to her income: $1,850 × 75% = $1,387.50.
| Salary alone | Salary plus 75% of rent | |
|---|---|---|
| Income used | $5,400.00 | $6,787.50 |
| Housing ratio | 57.67% | 45.88% |
| Total ratio | 62.30% | 49.57% |
| Inside FHA's 46.9% and 56.9% | No | Yes |
On her salary alone, Nadia would need $3,114.32 ÷ 46.9% = $6,640.34 a month to carry this building. The tenant's rent closes most of that gap, so her own pay only has to reach $6,640.34 − $1,387.50 = $5,252.84, and she earns $5,400. Her tenant's $1,850 also covers more than half of the $3,114.32 payment each month once she moves in.
Florida costs to plan for on a duplex
Insurance is the line that moves most in Florida. Many insurers ask for a four-point inspection on an older building, which reports on the roof, electrical, plumbing and air conditioning, and a wind mitigation inspection can earn credits that lower the premium. Get an insurance quote on the building early, while you're still inside your inspection period. If the property sits in a high-risk flood zone, the lender also requires flood insurance, and that cost goes into the payment.
If the duplex numbers come up short
Start with the rent. A unit leased close to market rent qualifies you for more than one with a below-market tenant, and every extra $100 of monthly rent adds $75 of qualifying income. A co-borrower who moves into your unit with you adds income and keeps the full 96.5% loan. Paying off Nadia's $250 car loan would drop her total ratio to 45.88%. And the seller can cover closing costs up to 6% of the price, or $23,700 on this building, which leaves the $13,825 down payment as the main cash item, and a family gift can cover that.
