I looked at HomeVestors (and some similar ones) when trying to sell a house in AZ a few years ago during a slump.
Basically they didn't want a sale, they wanted a long term lease that they in turn could sublease. If the house sold I basically got nothing, just that they paid my mortgage for me until it sold. They made the mortgage payments and advertised the house for rent. They never rented it and we ended up terminating our contract. I wouldn't use them again, left a very bad taste in my mouth. I'm thankful we didn't sell it, I have a feeling I would have been taken to the cleaners.
