Home Purchase Mortgage Calculators
Mortgage Program Calculators
From a lender's perspective, because the line of credit is only in your name and not your sister's name, you alone are legally responsible for the loan and the money you receive from your sister is not factored into your income to calculate your debt-to-income ratio when you apply for a mortgage. From the lender's standpoint, your sister has no legal obligation to continue making payments so they do not include the payments she makes to you in your income. One point I should make is that if you plan to sell your home and pay-off the line of credit before you buy a new home then the line of credit is not factored into your debt to determine your debt-to-income ratio.
