I think it is risky to estimate a fair market price without seeing a home. Livable is a term that can mean a lot of different things to a lot of different people.
If you are interested in selling this property, or if you are interested in purchasing it (you didn't say which), I would be glad to help you. As well as being a realtor, I am a certified real estate appraiser so my knowledge about value is greater than that of most realtors. Because of that, I am able to give you a very detailed competitive market analysis on this property without doing a full appraisal.
If you would like to get together to show me the property, I would be glad to give you an Adjusted Competitive Market Analysis in writing. Let's talk soon.
