Martin County loan limits
Martin County has a higher FHA limit than most Florida counties because local home prices run higher. On a single-family home that's $603,750, enough for a price up to about $625,000 with 3.5% down.
| Home | FHA limit | Conforming limit |
|---|---|---|
| Single-family | $603,750 | $832,750 |
| Duplex | $772,900 | $1,066,250 |
| Triplex | $934,250 | $1,288,800 |
| Fourplex | $1,161,050 | $1,601,750 |
These are the limits for the 2026 limit year from HUD and the Federal Housing Finance Agency. They update on this page on their own when the agencies post new ones. VA has no loan limit for a veteran with full entitlement. Look up any county.
What Martin County buyers can reach by income
Housing programs measure income against the area's median. The rows below start at 60% of Martin County's median household income of $82,943 and run to 150%, each with a $400 car payment, a 650 credit score and $10,000 saved, at a 5.75% rate on a 30-year fixed loan, with property taxes at 0.74% of the price a year and $283 a month for homeowners insurance.
| Share of median | Income before taxes | Top price | With |
|---|---|---|---|
| 60% | $4,147 a month $49,764 a year | $246,000 | FHA |
| 80% | $5,530 a month $66,360 a year | $340,000 | FHA 100% financing |
| 100% | $6,912 a month $82,944 a year | $435,000 | FHA 100% financing |
| 120% | $8,294 a month $99,528 a year | $531,000 | FHA 100% financing |
| 150% | $10,368 a month $124,416 a year | $625,000 | FHA 100% financing |
Even the $10,368-a-month household stays about $1,000 under what Martin County's FHA limit allows with 3.5% down, so income sets the price here long before the loan limit does. Once the price passes what $10,000 covers as a 3.5% down payment, the table moves to FHA 100% financing and the price then depends on income alone.
Martin County by the Census numbers
The Census Bureau puts Martin County's median household income at $82,943 a year, the median owner-occupied home at $432,200 and the median rent at $1,569 a month. About 79.6% of homes in the county are owner-occupied. Here is what the QualRate calculator does with those numbers.
- A household at the median income, with a $400 car payment, a 650 score and $10,000 saved, reaches about $435,000 with FHA 100% financing.
- Buying at the median home value with FHA and 3.5% down takes about $6,860 a month in gross income with $400 in other debts, and about $15,127 in cash before any seller credit.
- The median rent of $1,569 a month would cover the full house payment on a home of about $189,000.
Three Martin County buyers, run through the calculator
- With nothing saved, a household at Martin County's median income ($6,912 a month) with $150 in card payments and a 650 score reaches about $435,000 with FHA 100% financing.
- A buyer earning $4,150 a month, 60% of the county median, reaches about $245,000 alone. With a parent on $1,500 a month of Social Security co-signing, that rises to about $364,000, because FHA grosses up the parent's non-taxable income by 15% before it counts.
- A veteran at the county median income with a $350 car payment and $0 saved reaches about $557,000 with VA.
