This house is 1626 sq ft. I think most other homes in this area are around 1450 sq ft. 1626 sq ft is probably the minimum that I would buy for a two stories home. Like you, I also think that the bigger ones will be around $450K and the smaller ones will be around $420K in 2008.
Although I don’t think this house will ever go down to below $300K ever. Actually I like sdrealtor method of calculating the “fair” price based on inflation of 4%.
