When you are borrowing an unsecured loan for your home improvement, you are getting a personal loan that does not require collateral attached to it. Generally, this loan is different from home equity loans like HELOCs, where the lender necessitates the borrower to have accumulated a specific amount of home equity.
If you are looking for a more extended repayment period, you will have to go with one of the equity loans. In addition, the interest rates are often high, and you must have a reputable credit record to get a better interest rate.
