Recommend requesting the seller’s existing ALTA Survey, building plans & floor plans, site map, seller’s prior Phase 1 & environmental reports (easy for them to ask lender for copy), full rent roll detail (including renovated/classic unit indications by unit, sqfts, building #’s, full detail), aged receivables report (will allow you to identify hidden delinquency / bad debt yet to be reflected in T12’s), general ledgers / capex ledgers back at least 3 years to ID major capital projects or damage that wasn’t disclosed initially.

Different age group people and different background.

I would love the buyout approach but given his age, in his 80s, I believe he wants to cause us harm in any way possible.

Given the age of the roof, is it necessary to get this fixed?

Replaced the aging roof, renovated kitchen, bath and mud room. relocated laundry to basement freeing up precious space in the home.

Listen to http://biggerpockets.com/show65 so you can see how I lost money and have more gray hairs than my age because of a having 20 tenants like yours in a 30+unit building in a war zone of Cincinnati.

What age did you say the roof was when you purchased the policy? 

There is so much here at BP, you can immerse yourself for ages.

Quote from @Jacob Sherman: ground up construction is always much cleaner . in a fix and flip there are many unknows that may pop up after the demo stage is complete  this guy knows what he's talking about. forget fix and flip. new construction also appraises 20% above at least existing depending on age plus land cost is cheaper and less competitive, especially in markets like columbus 

It probably would have solved your problem unless it was just an aging/untrained animal.
