Piggyback Loans in Florida: The 80-10-10 and What It Really Costs
A piggyback loan Florida buyers use to dodge mortgage insurance or a jumbo. It works, but the second lien is rarely as cheap as the pitch suggests.

A piggyback loan Florida buyers use splits the financing into two mortgages instead of one.
It avoids mortgage insurance and can keep you under the jumbo threshold. Our piggyback page covers the structure.
What 80-10-10 means
A first mortgage for 80% of the price.
A second mortgage for 10%.
Your own 10% down payment.
Because the first sits at 80%, no mortgage insurance applies to it.
The other combinations
80-15-5 uses a larger second and only 5% down.
80-5-15 uses a smaller second with 15% down.
The first is always 80%, since that is the point.
Which combination you use depends on how much cash you have.
Why people do it
To avoid mortgage insurance without saving a full 20% deposit.
To keep the first mortgage under the conforming limit and avoid jumbo pricing.
To buy sooner rather than waiting two more years to save.
All three are legitimate reasons.
The jumbo argument in Florida
Conforming limits are set by county, and South Florida's are higher than the national floor.
Above the limit, jumbo underwriting is stricter and often needs larger reserves.
Splitting the loan can keep the first inside conforming territory.
See our jumbo loan page for the comparison.
The second lien is the catch
It carries a higher rate than the first, sometimes much higher.
It is frequently a HELOC, which means the rate is variable.
A rising rate environment can erase the saving entirely.
Price the blended cost of both loans, not just the headline first rate.
Mortgage insurance cancels, a second lien does not
Private mortgage insurance ends automatically once you reach the threshold.
A second mortgage exists until you pay it off.
So the piggyback wins early and can lose over a long holding period.
See our guide to removing PMI.
Run the actual comparison
Add the first and second payments together and compare against one loan plus mortgage insurance.
Then ask how many years until the insurance would cancel.
Compare total cost over that period, not over thirty years.
The answer flips depending on the second lien's rate.
It complicates refinancing
The second lender must agree to stay in second position when you refinance the first.
That agreement is called a subordination and it is not guaranteed.
It takes weeks and some lenders simply decline.
Buyers rarely think about this until they want to refinance.
It blocks PMI removal on other structures
A second lien generally prevents cancelling mortgage insurance on a first that has it.
That is not an issue on a true piggyback, since the first has none.
It matters if you later add a second to a loan that does.
Keep the interaction in mind before opening a home equity line.
Qualifying for both
Both payments count in your debt-to-income ratio.
A HELOC is usually assessed on its fully drawn payment.
So the piggyback does not make you qualify for more house.
It changes the cost structure, not your borrowing capacity.
Who genuinely benefits
Buyers with 10% saved in a high-priced county where the jumbo threshold is close.
Buyers expecting to pay the second off quickly from a bonus or a sale.
Buyers who would face expensive mortgage insurance due to credit or loan size.
In those cases the arithmetic is often clearly favourable.
Who should not bother
Anyone who can reach 20% down within a reasonable time.
Anyone whose second lien would price several points above the first.
Anyone likely to refinance soon, given the subordination problem.
A single loan with cancellable insurance is simpler and often cheaper.
The lender-paid alternative
Some lenders offer a higher rate in place of monthly mortgage insurance.
That has no cancellation point, so it only suits a short holding period.
It is worth pricing as a third option alongside the other two.
Ask for all three quotes on the same day so they are comparable.
Florida closing costs on two loans
Documentary stamp tax applies to each note, and intangible tax to each mortgage.
Two loans mean two sets of those charges.
That erodes some of the saving and buyers rarely account for it.
See our guide to closing costs.
Both loans usually close together
The first and second are underwritten and closed at the same time.
Often the same lender writes both, which keeps the timeline manageable.
Where two lenders are involved, the second must agree to its position up front.
Confirm both approvals before removing your financing contingency.
Paying the second off early
There is no mortgage insurance to cancel, so the saving comes from clearing the balance.
A second lien is usually the highest-rate debt in the structure, which makes it the right target.
Check the note for a prepayment penalty, since some closed-end seconds carry one.
Clearing it also removes the subordination problem from any future refinance.
Where to start
Ask for a quote on one loan with mortgage insurance and on the piggyback structure.
Compare the blended payment and the total cost until insurance would cancel.
