One advantage of these loans is that borrowers can get them very quickly—within a few days or even the same day—less time than it typically takes for a bank to approve a home-equity-based loan or line of credit, says Steve Allocca, LendingClub's president. What's more, you're not putting your home at risk when you borrow this way because it's not used as collateral against the loan. 
For a home equity line of credit, the best place to start is your own bank or credit union. Both usually offer lower rates to depositors. Check other sources to be sure. If you get a second mortgage, refinance, or opt for an FHA 203(k) mortgage, you're better off talking with a mortgage broker. A broker has more loan sources to choose from. When looking for a broker, check with people you know, and check any references you get. Contractors are another source of financing, but be wary: It's hard enough to choose a contractor and a loan when they're separate. And be suspicious of contractors who emphasize the monthly payment instead of the total cost of the job.
Most HELOCs come with a variable interest rate, which means your monthly payment can go up or down. The amount of interest you pay is determined by a number of factors, including interest rate levels set by the Federal Reserve, investor demand for Treasury notes and bonds, and the movement of benchmark rates used by the banking industry. Each factor can affect your interest rate.

3 LightStream will offer a rate .10 percentage points lower than the rate offered by a competing lender subject to satisfactory evidence being provided that you were actually approved for a lower rate with another lender for the same loan terms offered by LightStream by no later than 2 p.m. Eastern time one business day prior to loan funding. The Rate Beat program excludes secured or collateralized loan offers from any lender and the competitive offer must be generally available to any customer with a similar credit profile. Terms are subject to change at any time.
A home equity loan is another way to tap your equity without refinancing. Instead of getting a line of credit, as you would with a HELOC, you’d receive a lump sum of money. A home equity loan could make sense if you don’t want to refinance your first mortgage — if it has a very low interest rate, for example. But the interest rate would probably be higher with a second mortgage like a home equity loan than with a cash-out refinance.
Interest rates. The less interest you pay, the more loan you can afford. An adjustable-rate mortgage (ARM) is one way to lower that rate, at least temporarily. Because lenders aren't locked into a fixed rate for 30 years, ARMs start off with much lower rates. But the rates can change every 6, 12, or 24 months thereafter. Most have yearly caps on increases and a ceiling on how high the rate climbs. But if rates climb quickly, so will your payments.
