I bet you could sell your three homes and take whatever money you get from it and buy 3 homes with the cash and accomplish your goal. 

Honestly, your best bet is to reach out to a mortgage broker in the province you’ll be coming to and let them know what your plans are.  

Your time is even more precious than money; money can be replenished but those "six/few hours" are gone forever (bet you could have found something better to do than clean up his trash). 

I bet if I asked 100 agents in my market what a wholesaler is MOST of them wouldn't know the term.

Like anywhere, avoid crime ridden neighborhoods and the Class D stuff, but generally I think the Greensboro and Winston Salem metro markets are good bets.

Your best bet would be to buy a house that needs some work (undervalued to market of course), rent the rooms out to offset your payment, and save cash to rehab the property in steps over the course of a year or two. 

I bet you'd be underwater by $200-300/month when all is said and done.

If they got the flu the week before the first you can bet they won’t have all the rent money .

The only way around that would be a short term rental like Airbnb, but I bet the “average rate” is over $1.70 per day.

Your best bet is to get a steady job so you can qualify for a loan, buy a multi family home and live in one part and rent out the other(s).
