Not a Realtor, however I have bought and sold a lot of rental property through the years. At the end of the day, it's all about the comps ( comparable properties sold) in your area. In addition, the mortgage lenders are only going to lend so much on the property so if it is wildly overvalued, the purchaser won't get a loan.
I just sold a condo in June and had multiple offers and the sale price was $20,000 over asking. It is all market and demand driven in this Sellers Market.
As they say, asking is free so go for it. You never know who really, really wants your house.
This is an easy way to test the market -
