What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

Banks often have higher fees and less favorable rates, while online services like Wise offer more competitive options.As @Ryan Konen mentioned, other alternatives include Revolut for multi-currency transfers and OFX for large transfers without limits.

(Couldn’t really afford the place, didn’t have good enough credit to be worried about an eviction, etc etc..)2) They should have posted a 5-7-10 (depending on local laws) to “pay or quit” as soon as the ent was late and started eviction.

Agree that it is better to stop the bleeding, rent it at the lower rent with a term to end in a hopefully more favorable renewal time.  

For HELOCs without W2 income, look into local credit unions or community banks, as they often have more flexibility with alternative income verification and rental portfolios.

Due to a severe housing shortage for locals, Truckee is more favorable for long-term rentals.

The ability to do what you want, when you want, and have money coming in to support that.Things to work on: savings, credit, going to local real estate meetups, listening to podcasts, reading books.

If you chose to do the tenant a favor, its beyond me why he expects you to pay relocation also.

Since your involvement is primarily as a passive investor in syndications, you’ll need to evaluate if you meet these requirements, as REPS generally favors those who actively manage their properties.
