Is it suitable for other types of tenants?

You could find a  CPA  that is suitable and call your friend and  tell him now that you are getting bigger you feel you need a specialist in real estate.

I will let you know should I come across a suitable use case.All the best to you.Sandro

While FHA may not be suitable right now that doesn't mean there are no other options.

You do not need a work permit or a green card to buy property in the US, it will be tough to get a mortgage without either but I'm sure the IRS will welcome the extra revenue from an alien filing taxes.Your biggest problem IMHO is that you are not guaranteed entry at the borders and the activities you say you want to engage in when you come are almost certainly  not permitted on a visitors visa because I think they will be deemed as working. 

I am currently residing in Lincoln Nebraska on a visitor visa.

One other thought is that rather than trying to eat up your 1031 all at once and find three suitable replacements you may want to negotiate with your bank for a commercial line or commitment to fund your purchases but use only the first purchase to complete the 1031. 

6) Thoughts on the sister city Las Vegas Multifamily real estate investment considering that it has some good economic growth projects coming up (AMAZON fulfillment centre , SWITCH supernaps, FARADAY, Strip projects such as Genting Berhad’s $4 billion Resorts World Las Vegas, the $350 million MGM-AEG arena, and the Las Vegas Convention and Visitors Authority’s $2.3 billion Las Vegas Global Business District.)I am also looking for networking with other investors in this area including investor-friendly real estate agents.

She took out a reverse mortgage in the amount of $273,000 which needs to be paid off within six months.In short, it's a beautiful 17 acre property with a 3 bed 3.5 ba log cabin built in 2012 with a barn suitable for horses/cattle.

Yea I think I'm going to just keep looking for the best deal possible and if it's more suitable for flip, I'll do that.
