We did it in December of 2017. Went to an open house on a whim 6 months before we were ready to market ours, fell in love with the house and decided to make it happen. Since the plan had been to finish the upgrades on the current house before selling we found a flipper to purchase it instead. I didn't need to clear a bunch off of it (and wasn't going to anyways by the time the upgrades were factored in), I just needed to make it go away for more than I owed on it. We talked to 4 investors, and got offers, 2 of them were insultingly low (offering 25-30% of the comped value), 1 was from my realtor who was a personal friend and did some of his own investing, and the offer we went with was a local investor we didn't have a personal relationship with. In the end we went with the 4th offer, as it was about $10k over what I needed to get, and since my realtor was a friend I didn't want him to loose money on the deal, as from the numbers he and I both ran the margins were tight.
We went through it on an open house after the flippers had finished, and it was clear why they could offer what they did, their costs were lower than mine or my realtors would have been, as they cut a LOT of corners, and hid a bunch of stuff we were going to fix correctly...
