They are a discount buyer, so it is generally a bad deal to use them and you basically shouldn't unless you have no other option. It is similar to getting a pay day loan, or selling stuff to pawn shop or keeping a balance on your VISA. You are going to get a bad deal. I don't really know what to do about it. How can you ensure people are educated enough to know that a discount buyer is a buyer who will under pay for…
Legislating away discount buyers would be like legislating away payday lenders. The only thing accomplished would be to leave a hole in the market which will be filled by shady loan sharks.
2) Professional buyers contracts must allow a 30 day cooling off period in which the seller may back away from the agreement without punishment.
3) The 30 day cooling off period is initiated by the buyer prominently posting the offer in the local MLS service or similar prominent and accessible system. The buyer is responsible for ensuring any alternative offers during this period are conveyed to the seller.
4) The buyer and seller may avoid the 30 day cooling period by having a certified appraiser conduct an appraisal of the property and executing the sale at no less than 6% below appraised value.
I could throw in a couple other clauses in there to take care of people "brokering" regular sales to straw buyer or about requiring disclosures that recommend sellers consult with family and/or homeowner advocacy group within the 30 day cooling off period, but that is the crux of it.
This wouldn't eliminate the industry, but it would limit the actions of the worst offenders. Offers dramatically below market value should get counters. The worst consequence seems like it would be that the seller will get absolutely swarmed by realtors trying to convince them how much more money they would get with them.
