I was thinking about doing an inspection before leasing to reduce the risk of walking away from the option money.
I have looked at zillow. The initial value is low 1.1, but if you adjust the age (House originally built in 42, torn down to foundation in 2002 and rebuilt) The value is close to the lising price. Before reading all the housing bubble news I was thinking of offering 1.25, now I would feel nervous offering 1.1
