Florida Mortgage Calculator

Before you fall in love with a house, run the real numbers — not just principal and interest, but the property tax, insurance, HOA, and PMI that actually land on your monthly bill. I built this tool for the families I sit down with across Baker County and the First Coast, so you can see your true payment before we ever schedule a showing. — Amanda Kinard, licensed Florida Realtor (SL3383199)

What actually makes up that monthly number

Families are often surprised that the number on the loan estimate isn't the number that hits their bank account every month. Here's what I walk buyers through, piece by piece, so nothing catches you off guard after closing.

Property tax — different in every county we cover

Florida's average effective property tax rate runs around 0.80%–0.90%, but the actual bill depends on your specific county and city millage rate. Rural counties like Baker tend to run lower than the bigger metro counties. If this will be your primary residence, ask me about the Florida Homestead Exemption — it shaves about $51,000 off your taxable value and caps annual increases at 3% or CPI, whichever is lower.

Homeowner's insurance — budget for it honestly

Insurance is where Florida buyers get the biggest surprise, and I'd rather you know it now than at closing. A typical single-family policy runs $2,400 to $6,000 or more a year, driven up by hurricane exposure and the age and condition of the roof. Newer construction, hurricane shutters, impact windows, and an updated roof can qualify you for wind mitigation credits that meaningfully lower the premium — worth asking your insurance agent about on any home you're seriously considering.

Flood insurance — a separate policy, and worth checking even outside the mapped zones

Your homeowner's policy doesn't cover flood damage — that's a separate policy through the NFIP or a private carrier, and your lender will require it if the property sits in a FEMA Special Flood Hazard Area. Even outside those mapped zones, I encourage buyers to at least price it out; flooding doesn't always respect the map. See the Florida flood zones guide for how the zones work.

HOA dues, if the community has one

Not every community out here carries an HOA — plenty of Baker County properties don't — but where one exists, dues can range from a modest amount in a deed-restricted subdivision to a few hundred dollars a month or more in a community with shared amenities. It affects your debt-to-income ratio, so it belongs in the calculator, not as an afterthought.

PMI, and how you eventually stop paying it

If you're putting down less than 20%, expect Private Mortgage Insurance on a conventional loan — typically 0.3% to 1.5% of the loan amount annually. The good news: under federal law, your lender must automatically cancel PMI once your loan-to-value hits 78% of the original purchase price, and you can request it earlier at 80% LTV if you're current on payments.

Principal & interest — the part everyone thinks of first

This is the actual repayment of what you borrowed plus the lender's interest, calculated with the standard amortization formula: M = P [ i(1+i)^n ] / [ (1+i)^n − 1 ], where P is the loan amount, i is the monthly interest rate, and n is the number of monthly payments. For example, a $360,000 loan at 6.5% over 30 years runs about $2,275 a month in principal and interest alone — roughly $459,000 in interest paid over the full life of the loan.

Closing costs families forget to budget for

The monthly payment above is only part of the picture — here's what typically shows up at the closing table, one time, on top of everything else:

• 4-point inspection — many insurers require one for homes 25 years or older. Usually $100–$200.
• Wind mitigation inspection — $75–$150, and it often pays for itself through insurance discounts.
• Title insurance — customarily paid by the seller in Florida, though it's negotiable. Roughly 0.575% on the first $100K, sliding down from there.
• Doc stamps and intangible tax on the mortgage — $0.35 per $100 of the loan plus a small intangible tax, around $1,980 on a $360,000 loan.
• Documentary stamp tax on the deed — $0.70 per $100 of the sale price, about $3,150 on a $450,000 home.
