Miami STR Investing 2026: The Playbook Before You Buy

In 2026 Miami-Dade charges a 6% Tourist Development Tax on top of the 7% Florida sales tax, and Miami Beach caps most non-hosted short-term rentals outside a handful of zoned districts. That single sentence kills roughly 40% of the deals new investors bring to the table. If you are writing an offer on a Miami STR this year, you are not buying a house. You are buying a zoning certificate, a tax stack, and a pricing curve.

The Miami Market Map for 2026

Miami is not one market. It is at least seven, and each one has its own rules. Brickell, Edgewater, and Downtown allow STR activity in most condo buildings that opt in. Miami Beach restricts non-owner-occupied rentals under six months to specific zoning overlays, and fines run into five figures per violation. Sunny Isles, Bal Harbour, and Surfside each run their own registrations.

The city you pin on Zillow determines whether your deal works.

Most investors walk in believing Miami is a single, permissive beach market. It is not. The county sets one tax rule, each municipality sets another, and the condo association sets a third. A 2026 buyer who skips any one of those three layers ends up with a legal rental in the wrong building, or a beautiful building that forbids stays under 30, 90, or even 180 days. Before you offer, pull the condo docs, the municipal code, and the Miami-Dade TDT registration page. That three-document check takes 45 minutes and saves six-figure mistakes.

The Tax Stack You Actually Owe

Florida stacks three taxes on most Miami STR stays under six months. The state charges 7% sales tax. Miami-Dade adds 6% Tourist Development Tax. Some municipalities layer a resort tax on top. Airbnb collects and remits some of these automatically, but not all of them, and the gap is where hosts get penalty letters.

Airbnb remits the 7% state sales tax and, in most Miami-Dade cases, the 6% TDT. Vrbo and direct bookings may not. If you run a multi-channel stack, you are the backstop. The county does not care that Airbnb collected for one stay and Vrbo did not for another. They audit the address, not the platform.

For the deeper mechanics on deductions, registrations, and the monthly filing rhythm, the Florida STR tax deductions guide for 2026 walks the full workflow. Pair it with the occupancy tax collection breakdown so you know exactly what each platform handles.

I tell every new Florida host to set a monthly calendar reminder on the 1st. Download the prior month's earnings report, cross-check what Airbnb collected versus what the county expects, and file the gap before the 20th. [attr: florida-str-tax-deductions-guide-2026]

Underwriting a Miami Deal in 2026

Most pro formas you see in Facebook groups are fiction. They use peak-season ADR, forget the 13% tax, and ignore that Miami occupancy averages 58% across the year with heavy seasonality. A Brickell one-bedroom that clears $245 ADR at 64% occupancy grosses roughly $57,000 in revenue. Back out taxes, cleaning, management, insurance, HOA, and platform fees, and the real number lands closer to $32,000 before debt service.

Run the numbers twice. Once optimistic, once with occupancy at 50%.

Financing matters as much as the purchase price. Most Miami condos with STR permission sit in buildings that Fannie and Freddie will not warrant, which pushes buyers to portfolio loans, DSCR products, or cash. Expect rates 75 to 150 basis points above conventional in 2026. The financing guide for Airbnb investment property covers DSCR underwriting in detail, and it is the first conversation you should have with a lender before you tour a single unit.

The Miami-Specific Expense Line Items

• HOA fees: Brickell high-rises routinely run $900 to $1,800 per month.
• Hurricane insurance: Budget 1.5% to 2.2% of replacement cost annually.
• Resort fees and amenity charges: Many buildings bill separately for valet, gym, and pool access.
• Assessment risk: Post-Surfside, Florida condo assessments have spiked; pull two years of board minutes.

Pricing Strategy for a Seasonal Market

Miami has the sharpest season curve of any major U.S. STR market. December through April carries 70%+ occupancy at premium ADR. June through September, occupancy drops into the low 50s and ADR compresses 30 to 40%. Pricing software built on national averages will misprice your calendar in both directions.

Dynamic pricing tools handle this well if you set the floor and ceiling correctly. Your floor should be your true breakeven, which for most Brickell condos lands between $135 and $165 depending on HOA. Your ceiling should be 1.6x your seasonal benchmark for event weeks like Art Basel, Ultra, and F1. The comparison of Wheelhouse, PriceLabs, and Beyond goes through each tool's Miami-specific behavior.

Event Calendar Weeks That Move the Needle

Common Pitfalls Miami Buyers Hit

The number one failure mode is buying in a building that does not allow stays under the length you planned. Condo declarations are binding and often stricter than city code. A building in a Miami Beach overlay zone may legally permit STR, but the HOA docs require 90-day minimums. Your deal is dead before you close.

The second failure mode is underestimating assessments. Florida passed SB 4-D after Surfside, requiring structural integrity reserve studies. Many older Miami Beach and Sunny Isles buildings are now hitting owners with special assessments of $30,000 to $150,000 per unit. Bake that risk into your offer, or buy in a post-2010 building with healthy reserves.

The third is ignoring exit liquidity. STR-friendly buildings with Fannie warrantability sell fast. Buildings that do not sell, but only to cash or DSCR buyers, which narrows your pool and softens your exit price. Knowing when to walk away is a core skill, and Miami gives you many reasons to use it.

A Miami STR deal is not a real estate purchase. It is a stacked bet on zoning, HOA politics, hurricane insurance, and a seasonal demand curve that can flip 40% in either direction inside 90 days.

What the Average Rental Yield Looks Like

The average gross rental yield on a Miami STR in 2026 lands between 6% and 9% for condos and 8% to 12% for single-family homes in permitted neighborhoods. Net yield, after taxes, HOA, insurance, management, and vacancy, typically comes in 3% to 5% for condos and 5% to 8% for SFHs. These are realistic ranges, not the 15% cap rates that show up in pitch decks.

Yield compression has been real. Insurance alone has doubled in many buildings since 2022, and HOA fees in older towers are up 40 to 70%. Acquisition discipline matters more than
