Investment Property Loans in Miami, FL

In the City of Miami, single-family homes and duplexes in the T3 and T4-R zoning transects are not eligible for short-term rental or lodging use.

For investors: Underwrite a Miami house or duplex in T3 or T4-R on 12-month leases, whatever nightly income a seller shows. Confirm the transect on the city's GIS zoning map before making an offer, since guest stays are not an eligible use there.

In eligible Miami zones, short-term lodging needs a building permit and new Certificate of Occupancy, a management plan signed by any condo or HOA, a yearly Certificate of Use and BTR, and state DBPR licensing.

For investors: This is a conversion project, not a listing switch: plan review and inspections come before the new Certificate of Use. In a condo, the association's signature on the operational management plan is a gate, so secure it before closing on a unit bought for guests.

If more than 25% of a Miami building's units are rented to transient guests, the entire building must meet the hotel-type R-1 building code standards instead of residential R-2 rules.

For investors: In a fourplex, renting two units nightly is 50% and pulls the whole building into hotel-grade code work such as added fire and life safety measures. Keeping guest use to one unit in four stays at the 25% line.

Since October 1, 2024, Miami-Dade's Regulatory and Economic Resources department collects the 6% county tax on City of Miami short-term rentals; hosts file monthly, even with nothing due, and hold city and county receipts.

For investors: Register with the county before the first booking and file electronically. When buying a Miami property that already hosts guests, ask the seller for the county's Certificate of Compliance, because unpaid tourist tax tied to the operation can become the buyer's problem.

Deeds in Miami-Dade carry documentary stamp tax of 60 cents per $100 of price, plus a 45-cent per $100 surtax unless the deed transfers only a single-family residence.

For investors: On a $900,000 Miami fourplex the surtax adds $4,050 to the $5,400 base stamp tax, while a single-family house skips it. Settle early in negotiations who pays deed stamps, since on a duplex or small apartment building the surtax is a real line item.

Miami's business tax classes three or more units under one roof as an apartment house, at $27 for up to ten rooms plus $2 per added room, not counting baths, kitchens or closets.

For investors: For a Miami triplex or fourplex the receipt is a small yearly cost, due by September 30. The same schedule calls for a state DBPR license from five units up, a step to plan for when moving up to a small apartment building.

The City of Miami has been Class 6 in FEMA's Community Rating System since October 1, 2022, a 20% NFIP premium discount, while unincorporated Miami-Dade, rated separately, holds Class 3 and 35%.

For investors: A rental inside Miami city limits gets 20% off an NFIP policy, and a similar house just outside in unincorporated Miami-Dade gets 35%. On a flood-zone purchase that 15-point gap belongs in the expense comparison alongside price and rent.

Miami flood-zone homes that are new or substantially improved need the lowest floor a foot above base flood elevation; work over two years, five in coastal high hazard areas, counts toward the 50%-of-value test.

For investors: Timing matters on a Miami renovation: the city sums improvement costs within two years, or five on the coastal high hazard strip. Crossing 50% of market value can require elevating an older house, a cost few rehab budgets absorb.

Miami requires on-site drainage systems to be recertified every 120 months from final inspection; properties with three or fewer units are exempt, and four or more units need a registered professional engineer.

For investors: A fourplex is the smallest Miami rental caught by this rule. Ask the seller for the last drainage recertification and the maintenance log, since the city gives 60 days' notice before the due date and catch basins or wells may need cleaning or repair to pass.

Because Miami-Dade sits in the Florida Building Code's High Velocity Hurricane Zone, windows, doors, shutters, roofing and truss connectors used on a Miami building need county product approval.

For investors: Replacement windows, shutters and roofs on a Miami rental must carry county approval, which narrows product choices and raises costs. Keep the approval documents and permits, since wind mitigation inspections used for insurance credits rely on proof of what was installed.

The City of Miami adopted a total FY2026-27 millage of 7.3616 mills on September 24, 2026, for operations and general obligation debt, the same total it levied in FY2025-26.

For investors: The city levy is one slice of a Miami bill, alongside the county, schools and special districts. On a rental with $500,000 of taxable value the city portion alone runs about $3,681 a year, with no homestead exemption to offset it.

PortMiami's 2023 economic impact study found $61.4 billion in total economic activity, up from $41.4 billion in 2016, with cruise and cargo activity supporting 340,078 jobs.

For investors: Port, cruise and logistics work runs on shifts and needs housing within reach of downtown Miami, which supports year-round rental demand in central neighborhoods. Parking and transit access are practical selling points for tenants in this workforce.
