How Much House Can I Afford in South Florida? Start With Your Budget

How much house can I afford? In South Florida, start with the monthly payment you are comfortable with, not the price. At a 7% rate with 20% down, a $3,000 monthly budget buys a house of about $339,000, $4,000 buys about $491,000 and $5,000 buys about $643,000, once property tax, insurance and HOA are paid.

Think of your monthly budget as a carry-on suitcase with a fixed size. Insurance, property tax and HOA dues are the bulky items, so they go in first. Whatever space is left is what the bank can turn into a loan, and the loan plus your down payment is your price.

Below we walk through that method step by step, with the math shown, and explain why the same budget stretches differently in Parkland than in Boynton Beach.

Start with the monthly payment, not the price

Your true housing cost is principal and interest plus property tax, homeowners insurance and HOA dues. In our examples below, those extras take 32% to 40% of the payment, so pricing a home from the mortgage alone overstates what you can afford.

Online listings and lender pre-approvals tend to speak in prices. Your bank account speaks in months. Working backward from the monthly figure keeps the two in line and avoids the classic surprise of a home that fits the pre-approval but not the budget.

Two local costs deserve extra attention. Insurance in Florida is a large line item, and our guide to homeowners insurance in South Florida explains what drives it. Property tax resets after a sale: the home is reassessed at market value as of Jan 1 of the following year, so the seller’s bill is not your bill.

How the method works, step by step

Subtract the fixed costs from your budget, and the remainder is what you can spend on principal and interest. Because property tax rises with price, the cleanest way to solve it is to find the price where every piece adds up exactly to your budget.

1. Pick your monthly number. Use what you are comfortable paying, not the maximum a lender approves.
2. Subtract insurance and HOA. For a house, our home budget calculator assumes $400 a month of insurance ($4,800 a year) and $375 a month of HOA dues for a house in Delray Beach, the midpoint of its $300–$450 range.
3. Account for property tax. Tax is a percentage of price, so it is solved together with the loan. We use our calculator's 1.5% Delray Beach rate in the examples below.
4. Turn the rest into a loan. At 7.00% for 30 years, each $1,000 borrowed costs about $6.65 a month in principal and interest.
5. Add your down payment. With 20% down, the loan is 80% of the price.

Worked examples at $3,000, $4,000 and $5,000 a month

With 20% down at 7.00%, every extra $1,000 a month in budget buys roughly $152,000 more house. These figures assume a 30-year fixed loan and our calculator's assumptions for a house in Delray Beach: 1.5% property tax, $400 a month insurance and $375 a month HOA.

Each column adds up to its budget. Notice how much of the $3,000 budget goes to costs that are not the loan: $1,089, or more than a third. That is why a smaller budget feels tighter in South Florida than the price alone suggests.

Rates move the answer too. Rates were around 7% in October 2026, and Freddie Mac’s average for the week of Oct 15, 2026 was 7.40%. At 7.40%, the same $4,000 budget buys about $475,000, roughly $15,700 less than at 7.00%. Your credit score shifts your own rate, which our guide to how credit scores change mortgage rates explains.

Why the same budget buys differently in Parkland and Boynton Beach

Our calculator’s tax, insurance and HOA assumptions differ only modestly between cities, so a $4,000 budget buys a house of roughly $477,000 to $507,000 in each. What changes is what that price gets you, because local home prices are very different.

Using our calculator’s city assumptions, $4,000 a month buys a house of about $477,000 in Parkland (1.60% tax, $425 HOA) and about $484,500 in Boynton Beach (1.60% tax, $375 HOA). The gap is small. The market gap is not: Redfin’s September 2026 median sale price was $1,179,438 in Parkland and $337,315 in Boynton Beach, across all home types.

Run those medians backward with the same assumptions and the monthly cost is about $8,675 in Parkland and about $3,020 in Boynton Beach. A $4,000 budget sits comfortably above Boynton’s median and far below Parkland’s, where it points toward the smaller, less expensive end of the market.

Home type changes the math

Type matters as much as city. Our calculator assumes condos carry $100 a month of insurance for the unit, a quarter of a house's $400, but higher HOA dues, since building insurance sits inside the HOA. In Boynton Beach, where the condo HOA midpoint is $625, $4,000 a month buys a condo of about $492,100, a little more than the house figure. In Boca Raton, where it is $725, the condo figure, about $495,600, falls below the $507,400 a house would reach. Our condo, townhome or house guide compares the three in detail.

What lenders look at: debt-to-income

Lenders cap your payment with a debt-to-income ratio: your housing payment plus other monthly debts, divided by your gross monthly income. The limit depends on the loan type, your credit and your savings, and lenders often approve more than many buyers want to spend.

That is why the comfortable number comes first. A pre-approval tells you the ceiling; your monthly budget tells you what still leaves room for the rest of your life. Car loans, student loans and card minimums all count against the ratio, so paying one down before you apply can raise what you qualify for.

Cash you need besides the monthly payment

Your budget covers the months after closing; you also need cash on closing day. With 20% down, that is $98,137 on the $490,687 example, plus closing costs and prepaid items.

• Closing costs: Bankrate, citing Lodestar data for 2025, puts the average Florida figure at $8,492, about 1.82% of the average sale price.
• Prepaids and escrow: lenders typically collect the first year of insurance and initial deposits for taxes and insurance.
• A cushion: keep reserves for repairs, moving and the first hurricane season.

If 20% down is out of reach, a smaller down payment changes the math and adds mortgage insurance. See FHA vs. conventional loans in Florida for that trade-off, and closing costs in Florida for the full list. Then enter your own monthly number in our home budget calculator to see what it buys in Boca Raton, Delray Beach, Deerfield Beach, Boynton Beach and Parkland.
