@Robert Adams There's a lot of fail in your posts on this subject. You and @Casey Powers could start a traveling "Opendoor Misinformation" roadshow.
Again, for the record, I'm an employee of Opendoor and I will happily answer any questions I am able to. Frankly I hope there aren't too many folks on here falling for the FUD being pumped out by real estate "pros" with ulterior motives.
Also for the record, I want to reiterate the process for selling a home to Opendoor: Request initial offer > Accept/deny offer > Home assessment > Revised offer (typically with repair credit ask) > Accept/negotiate/deny revised offer > Closing.
Negative comments typically come from two camps: realtors, and sellers who have had a negative experience. Of the latter, they can be further broken down into two groups: those with an unrealistic idea of their home's value, and those who didn't understand the process (namely that we're coming out to verify the information they provided).
Regarding values: OD goes to a lot of trouble to research and value properties accurately. It's not foolproof; it doesn't work every time with 100% accuracy. But for someone to say, "They offered $295k and I know for a fact my home is worth $325k," is just hogwash. There is no way to know for sure, and realtors know it can't be verified, it can't be proven, and by the time their clients realize it, they're already locked into a six-month listing agreement. At that point, the realtor simply shrugs and says, "Well, the market dipped." (Opendoor, by the way, tracks properties where the seller declined to sell to us after requesting an offer. When that home eventually sells, we compare the sales price to our offer. If the delta is above a certain threshold, we'll go back and adjust the AVM for that area so it doesn't happen again.)
The reality is, Opendoor provides a side-by-side comparison of the numbers involved in selling to us vs. selling traditionally. It's much easier to understand than a HUD statement. There's zero obligation to request an offer and see this comparison. Realtors don't mention this because it shows that even with fees that are "higher than a realtor's 6% commission," the end costs are about the same either way. Don't believe me? Try it and see.
Got questions? Reach out and I'll do my best to answer them (until OD marketing/legal shuts me down, anyway). (On that note, these are my opinions, not those of Opendoor. Any mistakes are mine and mine alone.)
