Frequently Asked Questions
What is house hacking? +
House hacking is buying a 2–4 unit property with FHA financing (3.5% down), living in one unit, and renting the others. Tenant rent covers part or all of your mortgage — letting you build equity and cash flow while living nearly rent-free.
Can I use FHA financing to house hack in Florida? +
Yes. FHA loans allow 3.5% down on 2–4 unit properties if you occupy one unit as your primary residence. You must live there for at least 1 year. FHA loan limits in Florida range from $498,257 (most counties) to $1,149,825 (Monroe County/Keys).
What's the best city in Florida to house hack? +
Jacksonville offers the best house hack math — duplexes under $320K generate $1,200–$1,600/unit with 3.5% FHA down (~$11K). East Tampa and Gainesville near UF are also strong. Miami duplexes work but require more capital ($450K+ prices mean $15K+ FHA down).
How many units can I buy with FHA financing? +
FHA financing covers 1–4 unit properties. A fourplex is the maximum for FHA house hacking — three tenant units generating rental income while you occupy the fourth. Conventional loans can finance 5+ unit apartment buildings but require 25% down.
Do I need to disclose rental income on an FHA loan application? +
Yes. For 3–4 unit properties, lenders can use 75% of projected rental income to offset the mortgage payment when qualifying. This significantly improves your debt-to-income ratio and may allow you to qualify for a larger loan than a single-family purchase.
