HELOC in Miami: Use Your Equity and Keep Your Homestead Savings

Short answer

A HELOC lets a Miami homeowner borrow against equity while keeping the first mortgage and the homestead tax savings: in the City of Miami the median homestead had a 2026 market value of $513,530 but an assessed value of only $276,400, a gap that selling or moving would reset. You borrow up to a set limit, pay a variable rate, and in Florida pay a one-time intangible tax of 2 mills on the full line plus doc stamps. Many owners use one for roof work, hurricane repairs or condo special assessments.

Miami equity and the Save Our Homes gap, as of October 2026

Our Florida HELOC guide explains the draw period, the variable rate and how CLTV limits work. Briefly: you get a credit line secured by your home, draw what you need, repay and draw again, and your first mortgage stays as is. This page is about City of Miami owners.

The Miami-Dade Property Appraiser's 2026 preliminary roll counts 41,247 homestead residences in the City of Miami. For them, as of October 2026:

• Median market (just) value: $513,530
• Median assessed value: $276,400
• Median taxable value: $220,951

The gap between market and assessed value comes from Florida's Save Our Homes cap, which limits yearly increases in a homestead's assessed value to the lower of 3% or the change in the CPI. The cap resets on a change of ownership, which the statute defines as a sale, foreclosure or transfer of title.

That is why many long-time Miami owners prefer a HELOC to selling. A HELOC does not transfer title, so your assessed value keeps its cap. The lender, however, lends against today's appraised market value, not the assessed value on your tax bill. A home assessed at $276,400 may appraise near or above $513,530, and that difference is equity you may be able to use.

Homestead protection does not cover a HELOC

Florida's Constitution protects a homestead from forced sale by most creditors, but it lists exceptions, including obligations for the purchase, improvement or repair of the home, and taxes and assessments on it. A HELOC is a mortgage you sign on the home. If you do not repay it, the lender can foreclose, and the CFPB warns that a HELOC can cost you your home.

A foreclosure is also a change of ownership under the Save Our Homes statute, so you would lose the capped assessed value along with the house. Borrow for needs that protect or add to the home, and keep a plan for the repayment period.

The CFPB's HELOC booklet points out three risks to plan for:

• Payment jump at the end of the draw period. Many plans are interest-only while you draw, then repay over about 10 to 15 years, or require a balloon payment.
• Variable rate. The rate is an index, such as the prime rate or SOFR, plus a margin, so the payment can change even if you do not draw more.
• Line freeze. Lenders can generally freeze or reduce the line if your home's value falls or your finances change.

If you want a fixed payment for one known expense, a fixed-rate second mortgage avoids the variable rate. We price both.

Using a HELOC for roofs, hurricane repairs and condo assessments

In Miami the most common reasons owners ask about a HELOC are tied to the building, not to spending:

• Roof and wind work. Insurers in Florida look at roof age and condition, and a 4-point inspection or wind mitigation report can change your premium. A line of credit lets you pay the roofer in stages.
• Hurricane repairs and deductibles. A line opened before storm season can cover a deductible or repairs while a claim is processed. Lenders may freeze lines after a value drop, so it helps to open it while things are calm.
• Condo special assessments. Florida requires a milestone inspection for condo buildings three habitable stories or taller at 30 years and every 10 years after, and a SIRS every 10 years. Since December 31, 2024, associations that must do a SIRS cannot waive those reserves. The result in many older Miami buildings is higher dues or a special assessment.

A HELOC on a condo unit has its own hurdle: the lender reviews the building too. If the association has an unfinished critical repair, some lenders will not lend on the unit until it is done. We check this before you pay for an appraisal. If a line will not work, a cash-out refinance or a fixed second may.

Florida taxes on a new HELOC, and your right to cancel

Florida charges two state taxes when a HELOC mortgage is recorded, as of October 2026:

• Intangible tax: 2 mills ($2 per $1,000). On a line of credit it is paid on the maximum amount of the line, not on what you draw, and no more intangible tax is due on later draws.
• Documentary stamp tax: $0.35 per $100 on the amounts the mortgage secures. Florida's statute taxes the initial amount at recording and later advances as they are made, so your title or settlement agent will show how it is figured on your line.

Because the intangible tax is on the full line, a line much bigger than you need costs more up front. Size it to your project plus a cushion.

On a HELOC secured by your main home, federal Regulation Z gives you until midnight of the third business day after closing to cancel. Funds are not released until that period ends, so plan around it if a roofer or contractor needs a deposit.

Example only: a $150,000 line on a Miami house

Example only. A City of Miami owner's house appraises at $650,000 and the first mortgage balance is $250,000. Assume the lender allows a combined loan-to-value (CLTV) of 80%; each lender sets its own limit.

• 80% of $650,000 = $520,000 total debt allowed.
• $520,000 minus $250,000 = up to $270,000 of line available.
• The owner opens a $150,000 line for a new roof and a $40,000 special assessment on a condo the owner rents out.
• Intangible tax on the full line: $150,000 x 0.002 = $300.
• Doc stamps: $0.35 per $100; on $150,000 that would be $525 if taxed on the full line.
