There's another new one out there called "OfferPad"
https://www.offerpad.com, you put in your information and within 48 hours you get an offer.
I ran my house through it just for grins all while knowing what it's market value really is and was not surprised at the result. They make their offer and then subtract 6% commission AND anywhere from 0-6% concessions to the seller that THEY deem as normal in your market area.
Their offer before the deductions was about $25k lower than the lower end comps in the area.
So basically what they wanted was $25k profit on top of 6% commission
and 3% seller concession to buyer. Not bad if you can con someone into paying $25k PLUS 9%.
Oh, but they'll pay for your move if it's within 100 miles...
