• Your house payment alone (including principal, interest, taxes, and insurance) should be no more than 28 percent of your gross monthly income. The maximum debt-to-income ratio rises to 42 percent on second mortgages. Some lenders go even higher, though fees and rates get expensive — as will your monthly payment. However, a debt-to-income ratio of 38 percent probably is the highest you should consider carrying.
Homeowners with limited equity can get an FHA Title I loan for improvements that make a home more livable and useful, including accessibility improvements and energy conservation improvements. These loans can’t be used for luxury items such as swimming pools or outdoor fireplaces, however. Loans for less than $7,500 are usually unsecured; the most a homeowner can borrow is $25,000 for 20 years to improve a single-family home. The lender determines the interest rate. You’ll need to find an FHA-approved Title I lender to get this type of loan. As with any loan, you’ll need good credit and a demonstrated ability to repay the loan. 
*Credit scores are based on information collected by credit bureaus and information reported each month by your creditors about the balances you owe and the timing of your payments. A credit score is a compilation of all this information converted into a number that helps a lender to determine the likelihood that you will repay the loan on schedule. The credit score is calculated by the credit bureau, not by the lender. Credit scores are calculated by comparing your credit history with millions of other consumers.
