Over priced properties

[Quentin Hamilton]

I got a offer under contract yesterday I put it in about a week ago at 70% of asking price which was 129900 at the time I offered 90k but after it was accepted I looked on the bay county appraiser site and the just value was only 68k it seems like almost every deal I get now I got to cancel because they were overpriced to begin with and 70% of asking price just isn't a big enough spread what should I do?
