Today, I am a licensed Physical Therapist here in Arizona on a temporary work visa (F1 CPT) with hopes of obtaining my H1B lottery selection in the next year or so.

I'm currently going for my nurse practitioner license, being paid for by the hospital I work at, and it's just busy work (so far).

Now onto the real estate...If you truly want to protect yourself against STR regulations only purchase property with the intent of  operating as an STR where these three principles apply: (1) the use is allowed, (2) the use requirements are protected by in place permitting and licensing and (3) the permissions are transferable through a sale.

Also make sure they have proper license and insurance and name you as additional insured for liability.

I double "co-hosters" in most markets are getting 25-30%.If property management interests you I would suggest you become a licensed and insured PM company to increase your credibility. 

Let me guess - you never verified if they are a licensed PMC or if they have proper insurance.Do they even have a website with an Owner's & Tenant's portal?

@Eric HemplerIf you are not employed by the sponsor then yes you must be a licensed broker-dealer.

What is the best and most cost efficient program to earn a real estate license in Texas?

Last year, the city required a bank statement, which was not overly difficult for me to produce; however, this year the city of Chicago required either a homeowners exemption or a state license showing the exact address and unit for the listed AirBnB. 

Does this person have any professional licenses?
