You'll need their lease, tenant ledger, copy of 3 day notice, proof of posting/mailing to prove your case.Suing broke people in Texas is a waste of time.

Right now I find that I can easily find properties but have been finding difficulty showing proof of funds making people  willing to  wholesale their properties.

The student requests no proof of the mentor's success in the industry but instead gets easily sold on the rainbows and pixie dust.

I see no rationale where they deserve an STR permit over a STRs that provided proof of paying transit occupancy tax and being good hosts (few complaints/issues, etc).  

Why can't you start with some smaller residential or small multifamily commercial properties to get your feet wet, show proof of concept and possibly try to take on larger deals.Or possibly find a local syndication group and become an employee under them learning the trade and finding a mentor in the space.

I was able to STR our first home after moving and it has been a great success.How were you able to use STR income as proof if income for the 2nd and 3rd property mortgages?

Bank statements for last 3 months and last years taxes should show proof on stability of rent payments. 

Standard down payment for a new primary mortgage typically range between 3%-5%If you need the rental income from the home you are departing you typically will need a fully executed lease and proof of 1st payment and security deposit

You see it when the ignorant state that banks are scamming everyone by charging COMPOUND interest, and their “proof” is the amortization table showing all the interest being paid over 30 years.

It’s a fairly sophisticated operation, with an unusually long time lag between first identifying the unclaimed funds, tracking the beneficiaries, obtaining a contract from said beneficiaries, gathering all the documents needed for “proof”, dealing with numerous government agencies, and finally hopefully having your client receive the funds and you getting paid.
