What a multi-unit HELOC requires

Each item below is a requirement of at least one HELOC we offer.

  • The building has 2 to 4 residential units. Mixed-use buildings are not eligible.
  • A credit score of at least 600 if you live in the home at one program, or 680 at the program that also takes rentals.
  • Debt-to-income of 45% or less on 2 to 4 units at one program, and 50% or less at the other (45% below a 680 score).
  • A line of $400,000 or less at the program that takes rentals. It does not allow 2 to 4 units above that amount.
  • No more than one existing lien on a 2 to 4 unit home at that same program.

Can You Get A HELOC On A Duplex Or Fourplex?

Yes. Both HELOCs we offer list 2 to 4 unit homes as eligible, with different score, debt and line limits.

A multi-unit HELOC is a line of credit on a residential building with 2 to 4 units: a duplex, triplex or fourplex. The HELOCs we offer stop at 4 units, so buildings with 5 or more units do not qualify. Mixed-use buildings are not eligible either.

If you live in one of the units, at least one program accepts scores from 600, permits co-borrowers, including one who does not live there, and sets debt-to-income at 50%, or 45% below a 680 score. Lines start at $15,000. Lines above $500,000 need a 700 score and a full appraisal.

If you rent every unit, the line goes through the program that accepts rentals and is qualified on your personal income. That program needs a 680 score, caps the line at $400,000, allows at most one existing lien, sets debt-to-income at 45% and does not lend on rentals in some states, including Texas and New York. Rental buildings held in an LLC are covered on our llc heloc page.
