It shows in the public record the current owner purchased for $140K but that might just be 1 of 2 mortgages on the property. You should consult the sellers disclosure statement which this property has. Everything is fixable, it just depends on your financial position & the individual needs of a property. I don't know if there's mold in the property but mold can be remedied, you'd have to consult with a licenced mold remediation company to discuss the how's and how much $$ for different methods & needs.
Start with the property disclosure statement, then engage the services of a professional home inspector to get the best evaluation of the current status of the property. They'd be the next level of investigation, you could also check with the town building/inspectional services dept. for recent permits etc. also check with the board of health & zoning to check for any issues as well.
Hope that helps,
