should I walk away from this deal?

[Por Ataxic]

I recently offered and got a property under contract. It is a single house divided into 2 units. The listing price was 225K however The seller is currently out of town and agreed to sale it for 217K. After thorough professional inspection, there are a lot of minor issues which may cost me up to 8500$ to fix it.  The seller offers me just 1500$ credit. The house is renting for 2450$ per month. It is an old wood house and was built in 1929. Should I accept this offer or walk away from this deal?
