There are a few common mistakes sellers make. We are all pretty much familiar with them. The big one is I am priced here $$$$$$$$$ so I can negotiate. This is the biggest mistake I think . Seller overpricing leads to the home being overlooked.
However there is one mistake that sellers make that they really know nothing about. Many sellers think OK now is the time to fix up my home. So they put the home on the market and start "sprucing" it up. This is the cart before the horse. What most sellers are genuinely surprised at when we do listing presentation is the traffic trends. The first 2 weeks generally get you 80 percent of the showings. So if the house is not right then guess what !!!!
I find repairing while listing is the biggest problem area where sellers just don't get it. So show your sellers the numbers and if you have to wait a week or two before you list a property while the seller makes repairs then you are really enhancing your chances to sell
