Buying a House in Miami Beach

Why the house index rose while the city overall barely moved

Miami Beach's all-homes value rose 1.8% last year and 16.9% over five years, numbers driven by the condo stock. The single-family figure moved much faster, up 7.8% in a single year. A typical house now costs more than five times the typical condo.

The reason is supply. Of roughly 82,031 residents, most live in buildings with 10 or more units, and the detached houses that exist are concentrated on the bay-side islands, in Mid-Beach and in pockets of North Beach. Very little new land becomes available. Most house sales are older homes being renovated or torn down and rebuilt, so you are often buying a lot with a structure on it, and you should run the numbers both ways.

Price by bedrooms on Miami Beach

• 3 bedrooms: about $2,308,466
• 4 bedrooms: about $3,562,334
• 5 or more bedrooms: about $7,374,299

The fourth bedroom adds about $1.25 million on average, and the step to five bedrooms more than doubles the price again. Those jumps reflect location more than square footage: larger homes sit on waterfront lots, and five-bedroom houses are mostly new construction on the islands.

For comparison, Coral Gables has a typical all-homes value near $1,571,133, and Miami's single-family index is about $664,415. Buyers who want a house near the beach on a lower budget often end up comparing a Miami Beach three-bedroom with a larger house on the mainland. The trade-off is lot size and space against the island location.

Elevation, flood zone and the age of the house

The median year built for Miami Beach housing is 1969. Many houses were built at elevations that would not meet today's rules for new construction, and the city has been raising streets in several neighborhoods to deal with tidal flooding. A house that now sits below its street can collect runoff.

Before you commit:

• Get the elevation certificate and compare the finished floor to the base flood elevation for the lot.
• Check the FEMA zone. Much of the island is mapped in high-risk A or V zones, where a mortgage lender will require flood insurance.
• Get a flood quote from both NFIP and a private carrier. NFIP building coverage has a cap, which many Miami Beach houses exceed, so excess flood coverage may be needed.
• Ask about any past water intrusion and claims.

If you plan a major renovation, talk to an architect early. Florida's substantial improvement rules can require bringing an older house up to current flood standards once work passes a set share of the building's value.

Seawalls, docks and the waterfront inspection

Waterfront lots dominate the upper end of this market. The seawall is the owner's responsibility, and replacing one is a major expense that a standard home inspection does not cover. I ask for a separate marine or seawall inspection on any waterfront house, along with the permit history for the wall and dock. Check the wall's cap height as well, because the city has set minimum heights for new and rebuilt seawalls.

Inside the house, the usual Florida checklist applies: roof age and type, a wind mitigation inspection documenting roof-to-wall connections and impact openings, and a 4-point inspection on older houses covering roof, electrical, plumbing and HVAC. On a house of this value, also check whether the windows and doors are rated, because that affects both insurance and the cost of hurricane prep.

Insuring a high-value Miami Beach home

Citizens Property Insurance is the state-backed insurer of last resort, but it has eligibility limits on dwelling value, so many Miami Beach houses need a private or specialty carrier. Hurricane deductibles are a percentage of dwelling coverage, typically 2%, 5% or 10%, and apply once per calendar year. On a house insured for $2 million, a 5% deductible is $100,000 out of pocket before coverage pays for hurricane damage.

Closing costs and the property tax reset

With 20% down on a $2,457,421 house, the loan is about $1,965,937, which is a jumbo loan. Florida note stamps at $0.35 per $100 come to about $6,881, and intangible tax at 0.2% of the loan is about $3,932. In Miami-Dade the buyer customarily pays for the owner's title policy, a state-set rate that grows with price.

The property tax bill resets to market value after the sale. If the house becomes your permanent Florida residence, homestead takes up to $51,411 off the assessed value and, more importantly at this price, caps future assessment increases at 3% or CPI. Owners who keep their permanent home elsewhere get neither the exemption nor the 3% cap; their non-school assessment can rise up to 10% a year. Amendment 3 is on the November 3, 2026 ballot; the result is unknown as I write. This isn't legal or tax advice.
