Within a few years, I was able to pay back every penny I owed my family.

The loan is 12 months, pulls twice a month, the interest is minimal because I'm paying it off so fast. 

As long  the tenants pay the rent each month, increasing their rent will be very tough and getting them to leave will be extremely tough. 

The nice thing about the arbitrage business model, is the companies usually pay you a monthly rent, and then they handle all of the AirBNB stuff. 

HI @David SohnSituation 1: You don't pay for your brokers fee:In this situation you are not paying for a buyers agent and they would be paid via the seller.

Second, if you want a nice house in a nice part of town, you will have to pay for it, so will likely need to raise your purchase price.Third, if you want to go off-market, just know you are trading a lot of time for the possibility of maybe finding a deal.  

Make sure the tenants are paying market rent or above, otherwise your loan will be DSCR constrained.

Booking.com people pay a premium pricing and are good guests.

I have found that they worked really well when it comes to getting better tenants and better rents, and having less hassle, less headaches, and then getting a higher sales price; without paying closing costs or realtor fees.

Now, you need to figure out how to find deals and pay for them.
