Startup with a new type of home equity loan?

[Account Closed]

A few weeks ago I received a flyer in the mail from a company that offered a new type of equity loan. The loans are for up to $50-100k I believe. They collect 0 interest and require 0 monthly payments from the borrower. Then, when you sell your house, they take the money back, plus a fee based on the % increase in your home value since the loan was issued. If your home has lost value, they claim they will suffer that loss with you and you owe them even less than your borrowed in the first place. On top of that, they pay in as little as 14 days. I chuckled and threw it in the trash. Too good to be true. But now curiosity has set in and I'm trying to find out more. Has anyone heard of this company or this type of loan?
