Has anyone used Unison or other similar type company to pull cash out of their primary residence for investing? They refer to themselves as "investing alongside of you and your home's potential appreciation" I won't go into details about the program and really only did a tiny bit of research when I first heard of them back when I was looking for a primary residence.

Essentially they will give you up to a certain amount of cash without any debt payments in exchange for a percentage of the gain in your home.

My thought was some folks who are looking for cash to invest but don't want to mess with Heloc's etc could use something like this to get the needed cash without adding additional monthly debt. It seems as though you may be kicking the can down the road because eventually these companies will get their money back from you somehow but was curious if anyone has looked into it.
