Because you don't have a primary residence elsewhere, you could establish whatever place you buy as a primary residence, which would likely allow you to Airbnb (or short-term rent) your place while you're on assignment.

@Peter Schaub  as it relates to most of the BP wholesalers I think they fall into a two categories.. ones that are established and can close if they need.. and the beginners who have no hope of closing unless they resell..

Its taken me a few years of doing this to establish relationships. 

You must establish a specific set of search criteria.  

But keep in mind you will need to establish US credit using an EIN (this will take 6-12 months) and have a US bank account.  

Or just wait until at some point when her credit is established, have her buy the house for the remaining amount she owes? 

If you establish a reputation of taking advantage of agents and people in general, you won't be considered a reliable buyer and when competing, will often lose out to a buyer offering a little less money.

I completely agree that being specific with who you're targeting and knowing at least the basics of their facility goes a long way in establishing credibility.
