Buying a Vacation Home in Miami: Tax, Rental, and Structuring Considerations for 2026

A Miami vacation home is one of the most common purchases I am asked to advise on, and one of the easiest to get subtly wrong. The wrong building, the wrong ownership structure, or the wrong assumption about rental income can quietly cost a buyer tens of thousands of dollars a year — sometimes more — over a fifteen-year hold. The Miami market in 2026 is rich enough with options that getting the brief right matters more than getting the listing right.

Below is the framework I use with second-home buyers: a tour of the right neighborhoods for the use case, the tax differences from a primary residence, the ownership structures most often used, and how to underwrite rental income honestly.

First: Define How You Will Actually Use the Home

The single most useful exercise before any showings is to write down — in calendar terms — how the home will be used in year one and year three:

• How many weeks per year will you (and family) be in residence?
• Will you rent it? If yes, for what duration (annual, seasonal, 30-day-plus, true short-term)?
• Will guests or family use it without you?
• Will it be your primary residence within five years, or kept as a true secondary use?

The answers drive everything that follows. A buyer who plans eight weeks a year of use, no rental, and no intention to relocate is a different buyer than one who plans twenty weeks of use, three months of rental, and a path to Florida residency in five years. They should buy different properties, in different buildings, and structure ownership differently.

The Best Miami Neighborhoods for a Vacation Home

The brief shapes the neighborhood. A few useful frames:

For maximum walkability and turnkey condo lifestyle: South of Fifth (South Beach), Bal Harbour, Brickell, Edgewater, Coconut Grove waterfront condos. Lock and leave; concierge; resort-style amenities.

For single-family vacation use with privacy: Coral Gables (south of US-1), Pinecrest, Coconut Grove (single-family pockets), Key Biscayne, Bay Harbor Islands. Yard, pool, garage; less concierge, more responsibility.

For oceanfront with rental optionality: Mid-Beach (Faena District, Eighty Seven Park), Surfside (FENDI Château, Surf Club, Four Seasons at the Surf Club), Sunny Isles (Estates at Acqualina, Porsche Design Tower). Some of these allow rental durations that pencil as income; many do not.

For boating and dockage as the central feature: Coconut Grove single-family waterfront, Sunset Islands, Venetian Islands, Key Biscayne, Fisher Island. Dock first, house second.

Be honest about which of these maps to actual use. A buyer who imagines herself walking to Lincoln Road in the morning and then driving to Coconut Grove for dinner is, in practice, going to live in one of those two places — not both.

The Tax Picture: Florida vs. Your Home State

Florida's tax structure is part of the value proposition of a Miami second home, but it is not a complete tax substitute unless and until you establish Florida domicile.

Florida has no state income tax. This is the most-cited advantage and the one most often misapplied. A vacation home does not, by itself, convert your state-tax residency to Florida. To shift state-tax residency, you must establish domicile through a combination of physical presence, voter registration, driver's license, declaration of domicile filing, and (in most cases) re-orientation of where you spend more than half the year.

Florida property tax: the homestead exemption does not apply to second homes. Florida's homestead exemption — and the Save Our Homes 3% annual assessment cap — applies only to your primary residence. A second home in Miami-Dade is assessed at full market value annually, and the assessment can rise without the cap that homesteaded properties enjoy. This is the single most-overlooked carrying-cost item in second-home underwriting.

Documentary stamp tax and recording. Florida imposes a documentary stamp tax of $0.60 per $100 of consideration on deeds in Miami-Dade ($0.70 elsewhere), and additional taxes on mortgages and notes. On a $3 million purchase, this is a meaningful five-figure number that buyers from no-doc-stamp states often forget.

Federal mortgage interest deduction. A second home's mortgage interest is deductible at the federal level, subject to the combined $750,000 acquisition-debt cap across primary and secondary residences. If your primary already absorbs the cap, the second home's interest is not federally deductible — which changes the after-tax cost of debt meaningfully.

Ownership Structures: Personal vs. LLC vs. Trust

The default question is: should the home be titled in your personal name, in an LLC, or in a trust?

Personal ownership. Simplest. Cleanest for a true second home that will never be rented. Lowest cost. Mortgage and insurance pricing is usually best in personal name.

LLC ownership. Common for buyers who plan rental income, who value liability separation between this asset and others, or who want some privacy on the public record. LLCs add annual filing and registered-agent costs, complicate mortgage availability (many residential lenders prefer personal name and will require a personal guarantee on an LLC-titled loan), and may forfeit homestead protection if domicile is ever shifted. For pure rental properties, LLC ownership is the default. For pure vacation homes, it is overkill.

Trust ownership. Most often a revocable living trust for estate-planning reasons — to avoid Florida probate on death, to keep title transitions out of the public record, and to coordinate with broader trust planning. For most family-principal buyers, the right answer is both: the property is held in an LLC owned by the trust, or held directly in the trust depending on lender constraints.

These are not interchangeable. Choose with counsel before you close, not after.

Rental Income: Underwrite It Honestly

The most expensive mistake I see in second-home buying is the buyer who assumes "I'll just rent it when I'm not using it" and treats that income as a real offset to carrying costs. A few hard truths:

Most condo buildings prohibit true short-term rentals. Annual or seasonal rentals (six-month, three-month, 30-day-plus) are the most common allowed durations. Daily and weekly rentals (Airbnb-style) are allowed in a minority of Miami buildings and are restricted by municipality. Miami Beach has citywide short-term rental restrictions in most single-family zones. Confirm the building's bylaws and the municipal code before you underwrite a single rental dollar.

Even where allowed, rental income is volatile. Hurricane season (June through November) sees lower occupancy. Holiday peaks (December–April) drive most of the year's revenue. A common rookie mistake is to take peak nightly rates and annualize them — which produces a fantasy yield, not a real one.

Second-home loans usually prohibit rental. If you are financing the home as a second home (typically with 10% down and second-home loan terms), the lender's note often explicitly prohibits rental for the first 12 months. Violating this can technically trigger a default. Investment-property loans are available, with higher down payments and rates, for buyers who plan to rent meaningfully from day one.

Property management is not free. Real Miami short-term rental management runs 20–30% of gross revenue, plus turnover, utilities, and amenity fees. A 7% gross yield can quickly become a 3% net yield. Build the real model before you offer.

Insurance, HOA, and Carrying-Cost Diligence

Three items that every Miami second-home buyer should sign off on before closing:

Wind and flood insurance. Coastal Miami's wind-insurance market has compressed sharply since 2022. Get a binder quote — not a verbal estimate — before contingencies are removed. Flood insurance is required for properties in designated zones and is a separate policy, often more expensive than wind.

HOA reserve study and milestone inspection. Any Miami condo three stories or higher is subject to Florida's Structural Integrity Reserve Study and Milestone Inspection requirements under SB 4-D. Get both. Get the special-assessment history for the last five years. Get the current operating budget. A building with deferred reserves is not a bargain; it is a future special-assessment liability that the buyer assumes.

Property tax estimate, full assessed value. Get a real estimate — not the seller's tax bill, which reflects the seller's basis under the cap. As a second-home buyer with no homestead, you will be assessed at the higher of the sale price or current market value, and the prior cap does not transfer.

Frequently Asked Questions

Does a Florida vacation home help me avoid my home state's income tax? Not on its own. You must establish Florida domicile, which is a separate, evidence-based test involving physical presence, identification, and intent. A second home is one supporting fact, not a conclusion.

Can I deduct the mortgage interest on a Miami second home? At the federal level, yes, subject to the $750,000 combined acquisition-debt cap across primary and second homes. Consult your tax advisor.

Should I buy in an LLC? Default: no, for a pure second home with no rental. Default: yes, for an income property or where liability separation matters. Talk to counsel.

What's the most common second-home buyer mistake? Overestimating rental income and underestimating non-homestead property tax. Both are fixable in advance with realistic underwriting.
