Let’s say for example, If you purchase a rental property for $250k, but get an approval letter for $300k.

You'll have to contact the PR (Personal Representative) and make sure the PR has Letters of Administration.This gives the PR legal authority to sell the property..

-Rent due on 4/1-Tenant texts me on 3/30 asking whether there are any "adjustments on rent"-I sent her an email with the suggested letter on Bigger Pockets, with resources to help her pay rent, and requested she provide what she can pay and for letter from her employer proving she is impacted.

Yes, I am kidding.I might have my stories mixed up but I heard the CEO of AirBNB or some new company saved his tanking business by gambling their last couple thousand and winning big.

I would still send the registered letter. 

Anyone else getting a surprise escrow letter from mortgage providers that you have a shortfall due to "utility/irrigation" and I'm talking $500, $1000 or more per property that you owe?

Even if you plan to stick to the letter of the law and live separately for at least a year, any lender is going to look at that with a lot of skepticism. 

What about a mix of the two?  

Mix that with, what I consider, a poor decision that required all hosts to refund regardless of policy, and you have a lot of hosts that are doing what you say, going LTR or selling.

I'd probably respond with a "we're all in this together" letter...
