The term "subject-to" is mentioned on HUD statement lines 203 and 503, signifying that we are acquiring the property subject to the existing mortgage terms. Despite its long history, some seasoned investors and brokers may not be familiar with the subject to strategy, and may raise concerns about its legality.

When a borrower is obligated on a mortgage debt - but is not the party who is actually repaying the debt - the lender may exclude the full monthly housing expense (PITIA) from the borrower’s recurring monthly obligations if

the party making the payments is obligated on the mortgage debt, there are no delinquencies in the most recent 12 months, and the borrower is not using rental income from the applicable property to qualify.

In order to exclude non-mortgage or mortgage debts from the borrower’s DTI ratio, the lender must obtain the most recent 12 months' cancelled checks (or bank statements) from the other party making the payments that document a 12-month payment history with no delinquent payments.
