Multi-Unit Property Financing: 2-4 Unit Investment Guide

5 min read

Multi-unit properties (2-4 units) represent a unique opportunity in real estate - the ability to live in one unit while renting out the others, or to maximize rental income from a single property. Whether you're looking to house hack your way to homeownership or build a rental portfolio, understanding multi-unit financing is essential.

What Are Multi-Unit Properties?

Multi-unit properties include:

  • Duplexes: Two separate units
  • Triplexes: Three separate units
  • Fourplexes: Four separate units
  • Converted single-family homes: With legal separate units

Properties with 5+ units are considered commercial real estate and require different financing.

Loan Advantages

Qualifying with Rental Income

How Lenders Calculate Income

For Owner-Occupied (House Hacking):

Example: Fourplex Purchase
Total Rental Income: $3,000/month (3 units)
Lender Uses: 75% = $2,250/month
Your Income Needed: Lower due to rental offset

Self-Sufficiency Test (FHA):

  • PITI + HOA must be covered by:
  • Your income + 75% of rental income
  • Makes qualifying much easier

Required Documentation

  • Rent roll or lease agreements
  • Comparable rent analysis (if no leases)
  • Property operating statement
  • Proof of security deposits
