How did you finance this deal?

*Soon after, I will be moving to the South, where I will purchase a relatively moderate-priced home (less than $350,000), likely a single-family, possibly a duplex.~ I will most likely purchase the first home (multi-family) using a bridge-DSCR loan combo or a FHA203K (3.5-20% down). 

It is possible to get 90% of your purchase price and 100% rehab funded as a first timer in 1-4 units.  

If you’re offering $450K, then you could offer to take over the $120K payments and seller finance the remaining $330K.

I would love to know whether it is possible to apply the BRRRRR method there or other creative financing over there as a foreigners.

Exactly.  20% down financing for investment property will not be easy but if you have a W-2, maybe it's possible. 

I even considered owner financing it to somebody more ambitious or at least has more time than me.During pondering what to do with the property it crossed my mind, it could make a good mail drop store.

Conventional financing will work for this just fine.

Start networking with other investors to increase your access to real estate deals.Put your house on the market yourself on Zillow and Facebook marketplace and see if you can sell it yourself as a seller finance deal on what is called a wrap mortgage; especially if you have a low interest.

I am a realtor and wholesaler, and I get some buyers looking for owner financing, some sellers need/prefer getting cashed out and there are some lenders I work with who can provide the financing however they run out of funds sometimes.
