No comps just as good as bad comps?

[Tyler Meade]

Came across a property in the mountain that is a potential deal but finding comps nearby is nearly impossible. Seeing that it practically sits alone and no sold comps within a 1-2 mile radius, a local agent said “no comps is just as good as bad comps” how do i take that? Its a ranch style home, 1100sqft, roughly 40-45k in repairs with mold that overtook the basement and black mold in the upstairs bathroom from a roof leak!! Anyone with mold experience, kind of making me shy away from it. Thoughts?
