(Your chance to rescind your offer is based on your conditions).what evidence were you provided that the rent roll was what the seller made it out to be?

One recent addition to this body of evidence is a July Government Accountability Office report showing that federal government agency offices were typically operating at about 25% of capacity in 23Q1.The slow recovery of utilization comes against the backdrop of a surprisingly resilient labor market.

If so, the smell would also be more evident at times of high humidity...

I also want to qualify for another mortgage soon, which means I need to provide evidence of legitimate long-term revenue, ie LTR lease etc. 

Generally a better use of the Memberships funds would be a high quality security camera system that provides evidence quality videos and screenshots; has remote access that offsite management or security remote guard services; or Board Members and Resident Manager can access and review at any time; is easy to review recorded video; and has storage for over two weeks worth of continuous video for all, or most, cameras. 

That would be the highest cap rate in DC, making this property unusually cheap...and theres a reason for that even if its not easily evident.

Not to mention if you do it wrong - you die, literally or at least burn your house down and when it's investigated (and it will be) and your insurance company finds evidence of arson (and they will) you're not only going to get your claim denied, you will be liable for the damage you did to the tenants contents and endangering their lives.

If a tenant flips out on such, that's evidence right there of there inability. 

Contact the manager immediately and demand he provide you with evidence of income/expenses within one business day.
