Thanks for the replies.
This is where working a half-century or more directly in construction prior to becoming a home inspector will pay dividends. If you have the expertise to add defect cost estimating and building code specific language comments to your reports you will no doubt be able to command more money for your services which should offset any implied risk
I have been a construction professional for 25+ years. As a specialized subcontractor, I know how varied estimates can be which is why I shy away from them in my
inspection reports. This particular caller made me even more wary.
