Thanks Joel and Jake_D.
I have panicked and missed a house because it had asbestos roof. So needed a rough estimate to replace such roof to factor in the costs when deciding on any future offer amounts. I know that just because it is asbestos, it doesn't need a change. Just wanted to be prepared for worst case scenario.
My rough estimate is that it will cost around 40-50K. Correct me if I am way away from a realistic figure.
Thanks again
