Should Your Parents Co-Sign? The Real Risks and Rewards for First-Time Buyers

Co-signing is becoming a lifeline for many millennials and Gen Z buyers—but it’s also surrounded by myths and hesitation. Tim Lucas and Craig Berry break down how co-signing actually works, what it does (and doesn’t) do to credit, and how families can structure it safely.
In this episode you’ll learn:
  • What co-signing really is: Only the mortgage account appears on the co-signer’s credit—everything else stays separate.
  • DTI myth-busting: After 12 months of on-time payments from the buyer’s account, the mortgage may no longer count against the co-signer’s DTI.
  • Ownership clarity: Title = ownership. A co-signer isn’t an owner unless added to the title—big difference from co-borrowing.
  • Protecting relationships: Why successful arrangements use monthly check-ins, shared access to loan info, and a 3-month emergency fund.
  • Exit strategies: Co-signers can be removed later through refinancing once the buyer’s finances improve.
  • The upside: When structured well, co-signing can help young buyers build generational wealth instead of paying rent.
