A refinance 30 to 15 Florida homeowners make cuts total interest sharply and raises the payment sharply. It works when income rose, rates fell, or retirement is fifteen years out. Florida's escrow growth is the caution.

A refinance 30 to 15 Florida homeowners make cuts total interest by a large margin and raises the monthly payment by a large margin.

It fits when income has risen, rates have fallen, or retirement is about fifteen years out. Florida's growing escrow is the caution. Our guide to 15 versus 30 year mortgages in Florida covers the choice at purchase.

The payment jump

A 15-year payment on the same balance runs roughly 40 to 50 percent above the 30-year payment.

The lower 15-year rate softens it slightly.

See our mortgage payment calculator.

Florida taxes and insurance sit on top unchanged.

The total payment is the number to test.

The interest saving

Total interest over the loan falls by more than half in most cases.

See our guide to how amortization works in Florida.

The saving is largest when done early in the 30-year loan.

Ten years into a 30, the remaining interest is smaller and so is the saving.

Run the schedule.

When it fits

Income has grown since purchase.

Rates are lower than the original loan.

See our guide to refinance break-even in Florida.

Retirement or another goal is about fifteen years away.

Reserves cover Florida's escrow surprises.

When it does not

The higher payment leaves no margin for insurance and tax growth.

See our guide to house poor in Florida.

The current rate is far below today's.

Cash would earn more invested.

A short expected hold.

The alternative: pay a 30 like a 15

Keep the 30 and send the 15-year payment voluntarily.

See our guide to principal curtailment in Florida.

The same payoff date if you never miss.

The option to drop back to the minimum if Florida costs spike.

You pay the higher 30-year rate for that option.

Rate difference

The 15 prices below the 30.

See our guide to 15-year refinance rates in Florida.

The gap changes with the yield curve.

A wide gap strengthens the 15-year case.

A narrow gap weakens it against paying extra on the 30.

Closing costs

Florida doc stamps and intangible tax on the new note.

See our guide to Florida doc stamps and intangible tax.

Title at the reissue rate.

A lender credit can cover them at a slightly higher rate.

See our guide to lender credits in Florida.

Qualifying

The higher payment must fit the debt-to-income limit.

See our guide to maximum DTI in Florida.

Full underwriting.

Some borrowers qualify for the 30 refinance and not the 15.

A 20-year term is the middle.

The 20-year option

A payment between the two and a rate close to the 15.

Fewer lenders quote it; ask.

See our guide to 40-year mortgages in Florida for the other direction.

Suits a borrower ten to twenty years from a goal.

Run all three.

PMI

A 15-year refinance at 80 percent or below removes PMI.

See our guide to removing PMI in Florida.

Faster amortisation reaches the cancellation point sooner if PMI remains.

PMI on 15-year loans is priced lower.

Two savings.

Escrow growth

Insurance and tax increases hit a 15-year payment the same way.

See our guide to escrow shortages in Florida.

A tight budget on the 15 has no room for them.

Keep the reserve.

The payment jump is fixed; the escrow jump is not.

Retirement timing

A 15 taken at fifty ends at sixty-five.

See our guide to retirement income and mortgages in Florida.

Entering retirement without a payment changes the budget.

Many Florida owners choose the term by that date.

A reverse mortgage later needs a paid-down loan anyway.

Investment alternative

The payment difference invested may beat the mortgage rate.

It may not, and it requires actually investing it.

See our guide to first-year homeowner costs in Florida.

The 15 forces the saving.

Be honest about discipline.

Recast instead

A lump sum and a recast lowers the payment without changing the term.

See our guide to mortgage recasts in Florida.

The opposite goal from a 15-year refinance.

Some owners do both: recast now, refinance to a 15 later.

Sequence to the budget.

A worked example

Five years into a 30 at a higher rate than today's 15.

The refinance to a 15 raises the payment by a few hundred and cuts remaining interest by more than half.

The payoff date moves from twenty-five years out to fifteen.

The Freddie Mac survey shows the two rates each week.

The borrower's income growth since purchase made it comfortable.

Testing the payment for a year

Before refinancing, send the 15-year payment on the current 30 for twelve months.

If it strains the budget, the refinance would too.

If it is comfortable, the refinance locks in the lower rate on top.

The extra goes to principal either way.

A year of evidence beats a projection.

Where to start

Run the 15-year payment with real Florida taxes and insurance added.

Compare it to paying extra on the current 30.

Then start a conversation and we will quote 15, 20 and 30 side by side.
