The Quick Read: A Miami-Dade HELOC on a home you already own triggers two Florida taxes at recording, note and mortgage stamps at $0.35 per $100 and a one-time intangible tax of 0.2%, both measured on the maximum line in the mortgage, while the county’s higher deed surtax never applies because no deed changes hands.
- The tax follows the recorded mortgage and its stated maximum amount, not the balance you draw.
- Miami-Dade’s extra deed surtax is a deed-side charge, so it stays out of a HELOC on a home you already own.
- Both charges are state taxes, so a lender fee waiver cannot remove them.
- How you document income does not change the tax.
- An oversized “just in case” line costs more up front than a right-sized one.
Plenty of Miami-Dade owners tap primary-home equity to fund the down payment on a rental. That raises a fair question about the closing bill. This guide walks through what the line costs at recording, how the line is underwritten, where the rules bend, and how to size the line.
How large a line the equity supports in Florida.
An equity line is sized by combined loan-to-value, occupancy, and credit — not by rental coverage. Switch the occupancy or the credit band and the ceiling moves with it.
Investment-property lines require a 700 minimum credit score; second-home lines start at a 640 minimum and primary-residence lines at 600, and the combined-LTV ceiling steps down as the credit band drops on primary-residence and second-home lines and holds on investment-property lines; the line cap steps down on primary-residence lines and holds at every tier on investment-property and second-home lines.
A debt-to-income ratio above 45% requires 680+ credit. Profiles under 640 are limited to single-family homes. At least 75% of the approved line is drawn at closing. Ceilings, floors, and caps update from Lendmire’s centralized guideline source.
Line estimate
Illustrative estimate only — not a quote, Loan Estimate, approval, or commitment to lend. The rate is an editable assumption; equity-line pricing is variable through both the draw and repayment periods and never converts to fixed. Occupancy and credit drive the ceiling together: an investment property tops out at 70% combined LTV (minimum credit 700, line cap $500,000); a second home tops out at 90% combined LTV (minimum credit 640, line cap $500,000), with the ceiling stepping down as the credit band drops (the cap holds at every tier); a primary residence tops out at 90% combined LTV (minimum credit 600), and its $750,000 maximum line is available only at 75% combined LTV or below with a 700-or-better credit profile (720 on the longer-runway program) and a full appraisal. Lines above $500,000 require a full appraisal. Credit, debt-to-income, property type, and full underwriting review all affect the final line.
Which Two Taxes Hit a Recorded HELOC?
Two separate state taxes apply. Documentary stamp tax applies to the mortgage. The nonrecurring intangible tax applies to the secured debt. Each has its own statute, its own base, and its own payer. Neither one is a lender fee.
Documentary stamps on notes and mortgages run $0.35 per $100, or portion thereof, per a Florida real-estate law firm. “Or portion thereof” means the base rounds up to the next $100. The intangible tax is 2 mills on each dollar of secured debt under Chapter 199 of the Florida Statutes. That works out to 0.2%.
Add the two and you get roughly 0.55% of the taxed amount. That is arithmetic from the statutory figures, not a quote, and it leaves out the Clerk’s recording fees.
| Tax | Applies to a HELOC? | Measured on | Does Miami-Dade change it? |
|---|---|---|---|
| Deed stamps | No, no transfer | Sale price | Yes, surtax on deeds |
| Note and mortgage stamps | Yes | Maximum secured amount | No, $0.35 per $100 |
| Nonrecurring intangible tax | Yes | Secured amount | No, 2 mills |
One caveat on the last column. Several calculators describe the note and mortgage tax as uniform across Florida’s 67 counties. That is consistent with how the state’s tax structure is built. Still, confirm the line items with your closing agent.
Why Miami-Dade’s Deed Surtax Doesn’t Touch Your Line
Miami-Dade stands out because of its deed tax. According to the Florida Department of Revenue’s documentary stamp tax guide, a Miami-Dade deed on anything other than a single-family residence carries $.60 plus a $.45 surtax per $100. That language sits in the guide’s section on documents that transfer real property.
A HELOC on a home you already own transfers nothing. It records a mortgage. So the county’s deed rate is the wrong lens for your situation.
That is why so many Miami-Dade doc stamp pages feel off to a homeowner with a line of credit. They are written for buyers. A buyer’s closing stacks deed stamps, note stamps, and intangible tax. Your HELOC skips the first one.
Two related myths come up often:
- Condos. Whether a condo counts as a single-family dwelling matters only for the deed-side rate. It does not change what the mortgage-side taxes cost on your line.
- Homestead. Nothing in the statute or the state’s guide ties the mortgage-side taxes to homestead status. The taxes attach to the recorded instrument and its amount.
Full Line vs. Drawn Amount: How the Tax Base Works
The tax is measured on the maximum amount secured, not on what you borrow today. Here is the sequence on a typical file:
1. The lender documents a credit agreement and a Florida mortgage.
2. The mortgage states a maximum principal amount, and the agreement is tied into it.
3. The mortgage is recorded in Florida, and both taxes come due at recording.
4. The closing agent pays the taxes to the Clerk, and the cost usually passes to you.
5. Later draws are not taxed again once the full line has been taxed.
State tax advice on a combined credit agreement and mortgage says the stamp tax is due on the amount secured, even if that amount is conditional. A Florida appellate opinion in the Barnett Bank case also affirmed that home equity lines secured by mortgages carry documentary stamp tax. The opinion measured the tax on the maximum indebtedness secured. Borrowers draw by checks that carry no separate promise to pay, so the mortgage and the agreement are the taxable instruments.
On this network, the structure narrows the unused-line question. At least 75% of the line must be drawn at closing, so most of what is taxed is also borrowed. The remainder is the part you pay tax on whether or not you ever touch it.
The $2,450 Cap Trap
Some pages repeat a $2,450 maximum on documentary stamp tax. That cap applies to unsecured notes and other written promises to pay. Another Florida legal explainer says there is no limit on the tax due for mortgages or liens recorded in Florida. A secured HELOC is uncapped. Sizing the line larger raises the bill dollar for dollar.
A Worked Example
The numbers below are illustrative arithmetic from the statutory figures. They are not a quote. The mortgage’s stated maximum is the base, and the example uses each $100,000 of that base.
| Line item | Calculation | Result |
|---|---|---|
| Note and mortgage stamps | $0.35 per $100 on $100,000 | $350 |
| Nonrecurring intangible tax | 0.2% of $100,000 | $200 |
| Miami-Dade deed surtax | Not triggered | $0 |
| Combined state taxes | $550 |
Every extra $100,000 of stated maximum adds about the same $550. Clerk recording fees come on top. Their current per-page amounts vary, so ask your closing agent for the exact figure.
For comparison, a DSCR purchase loan on a Florida rental carries the same two taxes on its own face amount. The HELOC and the DSCR loan are independent recorded instruments. Each is taxed separately.
Who Pays, and What Else Is on the Statement
The intangible tax is legally the lender’s liability, but the lender may pass it to you. In practice the cost usually lands on the borrower. Documentary stamps on the mortgage normally pass through the same way. Whatever the paperwork calls the line item, it is not income to the lender.
| Charge | Legal payer | Who usually bears it |
|---|---|---|
| Note and mortgage stamps | Paid through the closing agent | Borrower |
| Intangible tax | Lender | Passed to the borrower |
| Clerk recording fees | Paid through the closing agent | Borrower |
A lender can waive its own fees. It cannot waive a state tax. If someone tells you doc stamps were waived, ask which line item changed. Often a lender credit simply offsets the tax.
How Underwriting Treats the Line
Underwriting decides whether you get the line and how large it is. It does not change the tax. Qualification method is irrelevant to the tax. A line that is reviewed on documented income under the applicable program, subject to lender guidelines, is taxed exactly like any other recorded mortgage. For a related angle, see Lendmire’s piece Bank Statement HELOC Documentary Stamps for a Miami-Dade Home.
What the lender does look at is combined loan-to-value, or CLTV. That compares all liens on the home to its value. On a primary residence, the leverage ladder across Lendmire’s wholesale partners works like this, subject to lender guidelines and full file review:
- At 720 or better, 90% CLTV is available up to $500,000.
- At 700 or better, 85% CLTV is available up to $500,000.
- At 640 or better, 80% CLTV is available up to $500,000.
- Between 620 and 639, 70% CLTV is available up to $400,000.
- At 600, the program floor, 60% CLTV is available up to $400,000.
The 90% figure exists only at a 720-or-better credit profile. A larger line is a trade. At 720, you can take 90% CLTV up to $500,000, or a bigger line up to $750,000 at a reduced 75% CLTV.
Debt-to-income tops out at 50%, and it is 45% for profiles from 600 to 679. The lender reviews your file on the interest-only payment on the maximum draw. Lines at or below $500,000 ordinarily use an automated valuation instead of a traditional appraisal. A full appraisal is required above $500,000.
Business bank accounts need a 680 minimum for the deposit analysis. A 640 borrower can qualify for the line but cannot use business accounts. Florida is among the 16 states where Lendmire arranges these lines, as a broker working through select wholesale partners.
Structures and Variations
Two draw structures exist on primary residences and second homes. One has a 3-year interest-only draw followed by a 17-year amortizing repayment. The other, the longer-runway structure, has a 5-year interest-only draw followed by a 25-year repayment. Pricing floats across both periods and never converts to fixed. The line sits in first or second lien position as a standalone product.
Line size runs from $25,000 to $750,000. A line above $500,000 is primary-residence only. It needs a 700 or better credit profile (720 on the longer-runway structure), caps at 75% CLTV, and requires a full appraisal. Subsequent draws after closing carry a $1,000 minimum on the longer-runway structure.
Eligible properties include single-family homes, 2-4 units, PUDs, townhomes, and condominiums, including non-warrantable ones. Manufactured homes, co-ops, condotels, and log homes are not eligible. Title must be held by you individually or by an inter vivos revocable living trust. An LLC cannot hold title on this product.
An investment-property line works differently. It caps at 70% CLTV, runs only the 5-year draw and 25-year repayment structure, and tops out at $500,000. Tapping a rental carries the same two Florida taxes, measured the same way.
Where the Rule Bends
Most HELOCs fit the basic pattern. These edge cases can change the bill.
Older versus current guidance on future advances. Older state tax advice treated advances under a line as taxable one at a time, and only on the amount of each advance. The state’s current intangible tax guidance taxes the full line once, with no additional tax once it is paid. Treat the full-line approach as the current position, and confirm the treatment on your file with the closing agent.
Unfunded or conditional lines. The two taxes can diverge. The documentary stamp tax applies to the secured amount even if conditional. The intangible tax is not due if no obligation was secured at recording. Drafting decides which outcome you get.
Out-of-state execution. A note signed and delivered outside Florida is analyzed differently. If collateral sits both in and out of Florida, the intangible tax is apportioned by the value of the Florida property against the total property secured.
Exemptions. Chapter 199 lists exempt taxpayers, mostly governmental and certain nonprofit or credit union obligations. A typical homeowner’s HELOC does not fall in that group.
Unrecorded mortgages. The intangible tax is still due and is paid directly to the state, with timing that varies by file and lender. Until it is paid, an unrecorded mortgage may not be enforceable in a Florida court.
Increases and modifications. Raising the maximum line later generally means taxing the added amount again. How a given restructure is treated depends on how the documents are drafted, so ask the closing agent before you sign.
Deed transfers. Moving a mortgaged property into an LLC can trigger doc stamps on the unpaid mortgage balance. That is a deed-side event, not a HELOC cost. It matters here because the line product above cannot be held by an LLC. A property already deeded to an LLC needs a vesting change, or a DSCR cash-out instead.
The Investor Decision in Practice
Start with the purpose. If the line is a down-payment source for a rental, size it to the cash you need. A “just in case” line carries tax on the whole maximum from day one. The tax is not refunded if the line goes unused.
Then compare it with the alternative. A DSCR cash-out refinance on the rental itself typically tops out around 75% LTV across most of the network, with about six months of seasoning as the common expectation. Subject to lender guidelines, DSCR loans qualify primarily on property-level rental income covering the payment. Primary-home equity and rental equity are different pools with different costs.
On the DSCR purchase you plan to fund, most files land at 75%-80% LTV, with select programs reaching 85% LTV at roughly a 700+ score. Coverage of 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00, with leverage and terms adjusted. Clearing 1.00 is not the same as positive cash flow, because repairs, vacancy, and management sit outside the calculation.
A larger down payment can lift coverage, but it never erases leverage caps, credit floors, or reserve rules. The strongest files clear both tests: enough equity and enough rental coverage. For the rental side, the complete DSCR loans guide covers coverage, leverage, and reserves. For the rental-HELOC variant of this question, see Lendmire’s piece How Much Florida Doc Stamps Add to a Miami-Dade Rental HELOC.
Tax treatment of the funds can depend on how they are used and how the property is held, so keep clear records and speak with a qualified tax professional before relying on any deduction.
A short checklist before you sign:
1. Ask the closing agent for each tax line separately.
2. Confirm the stated maximum in the mortgage matches the line you want.
3. Ask whether any lender credit is offsetting the taxes.
4. Compare the recorded amount with the Clerk’s and the state’s published schedules.
Key Terms Defined
Documentary stamp tax: a Florida tax on mortgages, notes, and deeds, charged per $100 of the amount involved.
Nonrecurring intangible tax: a one-time Florida tax of 2 mills per dollar on debt secured by a recorded Florida mortgage.
Maximum secured amount: the highest principal figure stated in the recorded mortgage, which is the tax base.
Surtax: an extra county charge. Miami-Dade’s applies to certain deeds, not to a HELOC mortgage.
CLTV: combined loan-to-value, which compares all liens on a home to its value.
Recording: filing the mortgage with the county Clerk, which triggers the taxes.
Frequently Asked Questions
Does the Miami-Dade surtax apply to my HELOC?
No. The surtax is part of the deed rate, and a HELOC on a home you already own records a mortgage, not a deed. Note and mortgage stamps stay at $0.35 per $100.
If I only draw part of the line, do I pay tax only on that part?
No. Both taxes are measured on the maximum secured amount in the recorded mortgage. Later draws are not taxed again. On this network at least 75% of the line is drawn at closing, so most of the taxed amount is borrowed anyway.
Can the lender waive the doc stamps?
Not the tax itself. A lender can waive its own fees or offer a credit that offsets the tax. The state still receives the full amount.
Does bank-statement qualification change the tax?
No. The tax attaches to the recorded instrument and the amount in it. It does not depend on how income was documented.
How do I check my numbers?
Take the stated maximum, round the stamp base up to the next $100, and apply $0.35 per $100. Then apply 0.2% for the intangible tax. Compare the result with each line on your closing statement, and ask the closing agent to explain any gap.
