Yes. Where a Non-Borrowing Spouse has a delinquent FHA-insured mortgage, even if the property is located in a community property state, the borrower is still eligible for a HECM. Mortgagees (Lenders) must not consider the credit history of a Non-Borrowing Spouse in the credit analysis of the borrower. Whether the Non-Borrowing Spouse has a delinquent FHA-insured mortgage or not will not affect the eligibility of the borrower for a Home Equity Conversion Mortgage (HECM).
