But my goal was to pay it off before my son graduated high school, and it will be paid off after his junior year.

You'll now have a bunch of hits on your credit history as all of these various banks due their checks on you.

@Jerry Padilla There have been recorded times in history (90s, GFC) that rents dropped.

I intend to dedicate every waking second to REI until I leave for school in about 7 weeks, do you guys have any suggestions for the best way to go about this?  

Even if you verify that the dad makes plenty of money, if they suddenly decide to pack up and go home without telling you, you likely won't be able to collect a judgement anyway.You can ask for things like:- Passport, Visa- Verification of their enrollment in the school- Local ID like DL- Pay stub from DadAnd do your own digging.That being said, a lot of my friends are either landlords to Chinese student renters or are themselves Chinese student renters and they seem to all be happy with the arrangement.  

I got inspired to become a real estate investor after reading a book from a powerful man in history.

It's an awesome property 3 bed 2 bath, 1,300 sqft, tax value is $110,000, the house next door is for sale for $135,000, and it has long term tenants who have perfect rental history.

I don't see why you couldn't sell it now as there are many investors who buy knowing a property has tenantsAs part of the agreement a purchaser may request background check and credit history of the tenant.

Below I will provide an overview of a property that looks to meet most of the underwriting criteria I've established for a viable investment e.g. 75% ARV test, affluent neighborhood, great school district, strong resale market, etc., but thought this information would be useful for those who might answer. 

My first property was close to a new medical school in an area with a relative lack of housing, so I knew students would drive plenty of demand.
