You might be eligible for a Title I Home Improvement Loan. A Title I loan is a great option because it's guaranteed by the FHA in the event that you default, so it's a low-risk loan from the standpoint of the lender. Also, it might be your best bet if you have limited equity in your house because Title I loans under $7,500 don't require any pledge of equity.
If you tend to have trouble getting out of debt, keeping your finances organized or meeting deadlines, this isn’t a good option for you. Borrowers who are disciplined, detail oriented and spend within their means could find this to be the least expensive option. However, it may not be possible to borrow as much with a credit card as you could with a home equity loan or cash out refinance, depending on how much equity you have and how good your credit is.
