I keep in touch with the guy I sold it to (10 years ago) and he has had no issues with it ever since.If you are unsure, you could always get an inspection by a foundation specialist BEFORE purchasing.

Also, see if the inspector could explain or walk you through what he or she does during their inspection or what they look for.

I've owned and operated my welding business for 10 years now, and not having quality people in your corner, such as an accountant, can be pretty costly. 

These units were build in 2007, and the pictures of the units look fairly good, but again, until I physically get to inspect it with an inspector and my contractor, this is just an estimate.  

If they pick out certain items that would require a more detailed inspection they will note it in the report.

A non-exhaustive list of closing costs includes loan application fees, points, prepaid homeowners' insurance, appraisal fees, inspection fees, transfer taxes, escrow fees, attorney fees, recording fees, prepaid interest, prepaid private mortgage insurance, title insurance, and title search costs.Hope that helps.

Best bet is to get inspections and or professionals out to assess the systems and provide estimates.With the roof 20-50 years depending on the climate, area, type of shingle and type of roof.

You could make an offer with a due diligence period to give you a chance to get inspections, and check for any environmental issues (cars leaking fuel, oil, etc... could be an issue). 

I would want to add an inspection contingency to the mix. 

If it won't pass FHA or VA inspection it will be tough to get a buyer who has financing.
