Is it okay for me to ask for proof of death?

I have three years proof of income. 

His social proof is all about name dropping.  

If they choose to stay, they must show proof of income so you know it's affordable.

Then in my bigger unit I decided to use the $1.98 a sqft LVP and I have had nothing but problems. thought if I spent a little more and got the water proof stuff it would be better.

Not having to go find a good cleaner and handy person, proof of regular maintenance on the hard systems (A/C, Furnace etc) helps.

I've also taken pictures of each room so I have proof of the state of the furnishings etc.

However, communication issues with Lacey began almost immediately—she took two weeks just to send me a contract and was frequently unresponsive, blaming weather-related issues.She advertised the property as highly profitable, but when I asked for proof, she never provided any.

I’m specifically looking for responses with factual supporting proof whether it’s a criminal offense or not and what it could mean for the lender, less about my litigation.  

STRs are recession proof, I thought?
