Martin County Investment Properties & Multifamily for Sale

The best Martin County investment decision starts before you buy.

Live BeachesMLS listings matching this search in Martin County, Florida, updated throughout the day.

Multifamily property is scarce in Martin County, where the housing stock is mostly single-family homes, condominiums and club communities. The duplexes and small buildings that reach the market tend to be older, and the streets of Port Salerno, with cottages and duplexes outside any association, are a familiar source; Fishermans Cove is another name buyers meet. Ask for the rent roll, the leases and the true operating costs, and replace the seller's tax bill with an estimate based on your price. Older buildings need a four-point and a wind mitigation inspection before insurers will quote, and the septic or sewer connection belongs in the due diligence. Check that the zoning allows the unit count, and confirm whether the City of Stuart or Martin County rules on short stays apply to the parcel before planning on seasonal tenants.

What Investors Buy in Martin County

Investors in Martin County mostly buy homes rather than buildings, because small multifamily property is scarce. Annual rentals are the steady core: townhomes and newer houses in south Stuart, Palm City and the West Jensen development lease to families and to people working at the hospital, in the marine trades and for the county, and older houses in Port Salerno and North River Shores rent without an association to approve the tenant. Furnished condos on Hutchinson Island and in the 55-plus communities serve winter residents where the rules allow, and Indian River Plantation has a few oceanfront buildings that accept stays as short as a week. A third group buys older waterfront houses to renovate or rebuild. In Martin County, association leasing rules decide more of the return than the purchase price does.

Reading the Numbers in Martin County

Reading the numbers in Martin County starts with rebuilding the seller's figures around your own purchase. The homestead cap on the current owner's assessment ends with the sale, so the tax line in a listing is rarely the tax an investor will pay. Insurance comes next: an older roof, no impact windows or a low floor elevation can move the premium more than the rent moves. Association fees in older condominiums can rise after a reserve study or a milestone inspection, and club communities may add dues that a tenant never pays. Leases of six months or less carry Florida sales tax and the Martin County tourist development tax, and a seasonal plan has to absorb an empty summer. Finally, check the leasing caps and waiting periods many associations impose on new owners.
