Even if zillow did know how much to subtract from value, by internet is&nbsp;no good. You need help with a contractor to give estimates on all this work and materials. I'd get two estimates and compare and go with the contractor I trusted the most if they weren't too costly.

They would ask the questions for you and would help you make an informed reasonable offer since there are no offers. I am assuming this is a conventional <a href="http://www.zillow.com/mortgage/">loan</a> since <a href="http://www.zillow.com/fha-loan/">FHA</a> would not likely approve the loan since it doesn't have the basics. Please feel free to email me should you have further questions.<br/> Sun, 31 May 2009 05:23:00 GMT http://www.zillow.com/advice-thread/Do-zestimates-assume-the-house-to-have-standard-features-of-homes-in-area-such-as-a-c-unit-and-sink/220435/ 2009-05-31T05:23:00Z
