1) keep in mind that a homebuyer will see many other homes besides yours, if your home is overpriced they will find a better value elsewhere. Your overpriced home will help sell other homes.
2) A buyer willing to overpay for your property will have problems financing because your home will not appraise.
3) Your home will stay on the market for a long time and will make homebuyers ask themselves “what is wrong with that property?”. If that happens you should expect offers well below your asking price.
