The HW will need to addressed right away and you need to be prepared if the town inspector just happens by and notices the roof...

A couple of thoughts from a curmudgeonly old home inspector re Redfin and R.E. sales in general. 1) Judging from your excessive use of exclamation marks you're a natural for real estate sales!!!! 

I’d love to connect with local real estate guys who deal with this kind of thing (investors, realtors, appraisals, home inspectors) feel free to send me a connect request, would love to connect with you.

The inspector believes it may be a leak from the bathroom.

And selling for 69K There are pictures and it is in decent shape  Would you reccomend and appraiser  , inspector  to help me make a better choice  and PM company to run it smooth.Any advice appreciated  Nikolay Voronovich 

I was going to add a clause that the house has to pass inspection, but the longer I think about it if there’s is a damage behind the walls my inspector will not be able to tell.

@Wesley B Williams I would get a home inspector and a general contractor in there.

Try and catch pre-construction so you can have an inspector conduct a three-phase inspection (foundation, frame, and final) throughout the time they are being built.

What has your inspector said about repairs needed? 

Contact your local building inspector to apply for a building permit and your insurance company to inform them of the specifics.
