Homeowners today are sitting on a record amount of equity, thanks to the recent run-up in home prices, but a lot of them can't access that cash. They don't have the credit scores to qualify for a home equity loan or a cash-out refinance. Enter EasyKnock, a barely 2-year-old company that will give you cash for your home and then let you stay on as a renter for up to five years. At anytime during that lease, you can buy your home back.
