If you can lower the sales prices and get out this is the easiest solution.

I’m not an expert on this matter, but I don’t think those labels are 100% accurate..so I think it’s possible properties can get this label and not actually be in this status, or maybe it’s a label that’s been stuck in the property from before she inherited it.You’ve already checked taxes and mortgages.

Savvy listing agents know these are toilet paper.Honestly there just isn't a great solution for folks starting out with deals that Fannie won't touch... maybe that says something about just how risky it is to start with 202-level deals instead of 101-level. 

If suspected/in doubt, I would terminate rather than stand the chance of something hitting the fan and having my property labeled a "nuisance property."  

I like the “you can add a window unit” solution provided the AC is working to its best ability.

The problem to the solutions of having a window AC or portable on standby is that if your portfolio is large you will have to have $10s of thousands of dollars of ACs for "just in case" moments.

I personally prefer to be more on the advising and relationship side so I can give my clients more tailored solutions, help them avoid pitfalls, connect them to people that can help them grow and structure their portfolios and I treat this industry more as a relationship business rather than a transactional business.

Simple solution: Inform them that unfortunately you can’t accept ESA letters without being able to verify the validity of the letter by speaking with the local licensed mental health professional who prescribed them their ESA, so that you can verify that they have a legitimate disability requiring an ESA as well as that whoever prescribed it to them is a real licensed mental health professional who has an ongoing relationship with them beyond just receiving a one-time payment to “prescribe” the ESA. 

There are a few issues and solutions that I can think of, and some were already mentioned by the other investors:1.
