Last time I was looking for a house, my dealings with FSBOs went like this one:
(Modest home in middle class neighborhood. Surprisingly priced way above other homes in the same area. I call to check it out
Me: How many square feet is the house?
FSBO (addled sounding redneck woman): Uh ... about 17,000 square feet
Me: seventeen THOUSAND
square feet? Are you SURE?
Her: Uh ... yes
Me: Former aircraft hanger? Remodeled Home Depot?
Her: Uh ... no
Me: Bye now!
The house I bought was another FSBO that stayed on the market for months priced way too high. Then they got an agent and I was able to bargain the price down to $20,000 less than their original price.
I would think about selling my current home myself now because I've been through the process a couple times, and because my husband has worked for the county in deeds and records before and knows how to research property values, liens, etc.
