There are several types of loans that can be used for house remodeling. Many homeowners take out a home equity loan or home equity line of credit (HELOC) for that purpose. The home is collateral for the loan. Because of this, rates are typically lower. One could even use credit cards for home improvements, but the cost likely would be prohibitive. Each loan has advantages and disadvantages.
B and C loans. What if you have less than A credit or don't fit the usual employment or income mold? B and C loans are a fallback. While many banks offer them, so do credit unions, brokerage houses, and finance companies. You'll also find lenders that push B and C loans for debt consolidation with enticing introductory rates. Beware, though: Total interest and fees tend to be high because of the lenders' added risk. And since B and C loans lack consistent requirements and terms, comparing them is difficult.
I'd also take into consideration which projects will boost property value; those would probably be the best to finance. First of all, if anything is broken— roof needs replaced, HVAC systems need to be upgraded— that would be first on the list. There are also a million articles on which "upgrades" make the biggest difference in property value and while I'm not a real estate person I tend to think things like bathroom updates, kitchen updates, and finishing unfinished space like bedrooms and attics would be high up on that list. Building major landscaping structures probably isn't, and I wouldn't recommend financing to, say, put in a pool.
Your debt-to-income ratio: You can calculate your DTI by dividing all of your monthly debt payments by your monthly income. Lenders generally consider a DTI of 36 percent or less to be acceptable, but many lenders will consider borrowers with higher ratios, depending on their income. Anything getting close to 50 percent, though, may disqualify you.

Because terms and rates differ greatly between these niche loan products, it's also harder to understand just what you're signing up for. Steer clear of shady offers, especially payday loans. You should compare the terms, APR (annual percentage rate), and other costs of each loan to see which one makes the most sense. The Mortgage Professor offers many calculators for that tricky task.
