Does a HELOC affect my ability to refinance my first mortgage?
Ask USMI can help explain this answer and the published sources behind it.
Short answer
Yes. The CFPB says taking out a (HELOC) can affect a later of the first mortgage. The HELOC lender may have to approve that refinance and can refuse. If it refuses, paying off the HELOC may be required before the first mortgage can be refinanced.
Full explanation
A HELOC can stand in the way of refinancing the first mortgage. The CFPB says you may need approval from the HELOC lender before that refinance can close. That lender can refuse to allow the refinance.
If the HELOC lender will not agree, the CFPB says paying off the HELOC may be necessary in order to refinance. The brief does not say that a HELOC can always be subordinated, or that every HELOC lender will agree.
Whether a particular line can be subordinated, paid off, or left in place is a question for the HELOC lender and the new first-mortgage lender. This explanation does not guarantee any of those outcomes.
