As a buyer, I've had a terrible experience. I put an offer in and details were given in writing over a WHATSAPP account with a screenshot of DiP. And then I was checking frequently to see if the owner has replied if they accepted it or not. The very next day I'm having a text message saying they have accepted another offer and they won't even tell me what the next offer should be to top it and says the owner would not be accepting any other offers. What if I am willing to pay higher than the market price. If I am seller I definitely wouldn't want to miss that opportunity and would expect them to earn the maximum I can earn for selling my property and not shutting off people who would be willing to pay more. Really terrible experience.
