Complete House Hacking Guide
Written by Onias Derilus, Mortgage Capital · NMLS# 1859012 · Florida licensed mortgage broker
House hacking is buying a small multi-unit property, living in one unit, and renting the others so tenants help cover your mortgage. It is one of the most effective ways to start investing in Florida real estate.
This guide explains how house hacking works, the low-down financing that makes it possible, and how to run the numbers. Mortgage Capital, NMLS# 1859012, finances house-hacking purchases across Florida.
How house hacking works
You buy a two-to-four-unit property, occupy one unit as your primary residence, and rent the others. The rental income offsets your housing cost, sometimes covering it entirely.
Because you live there, you qualify for owner-occupied financing with far lower down payments than an investor would use.
Low-down financing
Owner-occupied multi-family loans allow FHA at 3.5% down, VA at zero for eligible buyers, and conventional as low as 5%. This is the key advantage that makes house hacking accessible.
Lenders count a portion of the projected rent from the other units, which helps you qualify for the larger property.
Running the numbers
Compare the total mortgage payment, including Florida insurance and taxes, against the rent from the other units. The goal is to live for far less than renting, or for free.
Budget for vacancy, maintenance, and the reality of being a live-in landlord. Even partial offset builds wealth fast.
Being a live-in landlord
Living next to tenants means handling repairs and occasional friction, but it also lets you manage the property closely. Many house hackers later move out and keep the property as a full rental.
Florida's strong rental demand supports this strategy in many markets.
Scaling from your first house hack
After a year of occupancy, you can repeat the process, buying another owner-occupied property with low-down financing and converting the first to a full rental.
This repeatable path is how many Florida investors build a portfolio without large down payments.
