@Alan Brown The insurance issue you mentioned actually is a huge problem in all areas with significant new multi-family development (FL, CA, AZ, CO, NY, Etc.) due to class action lawsuits alleging construction defects.

As others have said, the only reason to need an NDA on a SFR is because the party allegedly selling the property doesn't have it under contract and wants to protect themselves from a smarter investor who will actually get the property under contract so he/she has something to sell. 

However, my problem (or maybe its not and I'm making it one), is that the roof was allegedly replaced in 2018 by the previous owner of the property (not the current), and was not permitted.

Sarah Palin did not quit to make money, she quit because of all of the unfounded 'ethical allegations' were just too distracting for her to fulfill the job of governor.Here is THE question.

If you have a decent lease, it should include a provision that the tenant cannot use any alleged problems with the condition of the house to offset rent.

The allegations are suspicion of sub-leasing back in 2006/2007.

Allegedly, all were rented at one point, but the owner has been working on them as the leases ran out.4x 1BR: $425, 425, 500, 5002x 2BR: $6001x 3BR: $750Total Rental Income: $3800Revenue: $3800less Vacancy (10%): $380less Electric: $40 (Common Area)less Snow Removal: $80less Gas: $40 (Common Area)less Fire/Liability Insurance: $227less Water: $260less Sewer: $67less R/E Taxes: $533less MGMT Fees (8%): $274NOI/mo: $1900Debt Service: $831Cash Flow: $1069

If you can prove your allegations, it seems that you were negligently misled and relied on her misleading statements to your detriment. 

Even if it is very, very clear you would win if you found yourself in some legal trouble over an alleged violation, its still annoying to have to deal with so err on the side of caution I suppose haha
