Subject-To Deals in Florida — When an Owner Can’t Afford to Sell Through an Agent

What a Subject-To deal is, why owners with a 3% loan and thin equity can’t sell retail, the due-on-sale risk and Florida doc stamp rules, with live Hillsborough data.

The arithmetic that makes a retail sale fail

Equity on paper is not money in hand. Selling through an agent has a cost that comes off the top, and for a recent buyer with a small down payment it can be larger than the equity itself.

Nothing is wrong with that owner’s finances. They are current on a cheap loan; they simply can’t afford to sell it. That is the person a Subject-To offer is for — and it is a very different person from a distressed seller.

They are not a random slice of the county. Nearly all bought in 2020–2022 with very small down payments — the typical loan was about 98% of the price, which is FHA and VA territory — and most still live in the home. They cluster in the south and east of the county: Ruskin 33570 (100), Riverview 33579 (80), Wimauma 33598 (71), Ruskin 33573 (65), Tampa 33604 (38) and Riverview 33578 (29).

How a Subject-To deal works

1. The seller deeds the property to the buyer. Title transfers at closing like any sale.
2. The existing loan is left in place. It is not assumed, refinanced or paid off; it stays in the seller’s name and on the seller’s credit.
3. The buyer makes the monthly payments — usually through a third-party servicer, so both sides can see every payment.
4. The seller’s equity, if any, is paid in cash or on terms. With thin equity it is often small: the value to the seller is a closed sale without bringing money to the table.

The risks — for the seller first

The due-on-sale clause

Almost every mortgage lets the lender demand the full balance when the property is transferred. Federal law (the Garn–St Germain Act, 12 U.S.C. 1701j-3) lets lenders enforce that clause, and its exemptions — transfers to a spouse or children, into a living trust where the borrower stays a beneficiary, on the death of a borrower — do not cover a sale to an investor. A lender may never act on it, and many do not while payments arrive; but it is a legal right, not a technicality, and the seller should understand it before signing.

The loan stays on the seller’s credit

If the buyer stops paying, the late payments and any foreclosure are reported against the seller, who no longer owns the house. This is the single largest risk in the structure, and the reason servicing, insurance and a clear default remedy matter more than the price.

Insurance, escrow and taxes

• The seller’s homeowner policy does not follow the deed. A new policy is needed, with the lender kept as mortgagee.
• If the loan escrows taxes and insurance, the escrow account and any refund remain the seller’s unless the contract says otherwise.
• The seller’s homestead exemption ends; the next year’s tax bill can rise.

Florida specifics

• Documentary stamp tax is due on the existing loan. Under F.S. 201.02, consideration for a deed includes the amount of any mortgage the property stays subject to, whether or not the debt is assumed. A Subject-To deed on a $290,000 balance owes doc stamps on that amount ($0.70 per $100 in Hillsborough), not just on the cash paid.
• Homes in foreclosure are a different legal category. If a lis pendens has been filed, Florida’s foreclosure-rescue statute (F.S. 501.1377) puts strict contract requirements and prohibitions on “equity purchasers” dealing with that homeowner. Do not structure a Subject-To purchase of a home in foreclosure without a Florida real estate attorney. See What Is a Lis Pendens in Florida?
• Recorded mortgages are public. Each mortgage recorded with the Hillsborough Clerk carries an intangible-tax stamp (F.S. 199.133, 2 mills — 0.2% of the loan), which is how the original amount can be read from the public record. The interest rate is not recorded; it lives in the promissory note.

The cleaner alternative: a formal assumption

FHA and VA loans are assumable with the lender’s approval: the buyer qualifies, takes over the loan in their own name, and the seller is released. It takes longer and the buyer must qualify, but it removes the due-on-sale question entirely. On a VA loan, the seller’s VA entitlement stays tied to the loan unless the buyer is an eligible veteran who substitutes their own. When a loan is larger than the price paid — the VA funding fee financed on top — it is likely a VA loan, and an assumption is worth raising first.

How to find these owners

The signal is not distress, so distress lists will not find them: of the owners counted above, almost none are in foreclosure or behind on taxes. You need three facts the county already records — when the current mortgage was recorded (which tells you the rate era), how large it was (from the intangible-tax stamp), and what the home would sell for today — and the arithmetic above. REI Radar reads those recorded mortgages for Hillsborough and flags owners with a sub-4.5% loan and 15% equity or less; the “Creative finance” filter in the dashboard lists them, lowest equity first.

How the numbers are estimated. Loan amounts come from the intangible tax paid when each mortgage was recorded. Rates are the Freddie Mac weekly average for the week of recording, because the actual note rate is not public. Balances assume a 30-year loan; value is the assessed just value multiplied by what Hillsborough homes have actually sold for relative to it over the past year. Treat every figure as an estimate to confirm with the owner.
