Yes, this is a very popular method among investors. 

What's even more befuddling to me is a popular "guru" who has a dedicated thread on BP of worshippers, is telling people with as little as a $1,000 to $5,000 to their name, that it is profitable lending in 3rd position on a property he is paying full price for on the MLS. 

But then, as short-term rentals became ever more popular, Americans tourists started thinking wait a second "We're paying so much for staying for a week at that short-term rental.

With short term investing too, if you have a popular property, I would say that rates almost do not matter because you are making so much money!

For instance, the Poconos have remained a popular option because of its year-round tourism draw, with skiing and lodging in the winter, hiking in the fall, and camping around lakes in the summer.As others have said, going into markets with one draw is risky.

Subject to sales were a lot more popular when interest rates were 15% +( 1979-1983), there were no “due on sale” clauses, and few real estate transactions were occurring.However, there are still some benefits to the seller in particular situations if (1) the seller understands and accepts those risks and (2) certain safeguards are utilized to modify some of those risks.A few possible seller motivations for selling subject to1.

Have good customer service?

Just like everyone out their who are  Big company's like Walmart, Target, etc. have daily issues with customers that need to be resolved in person or online or complaints with the BBB. 

Got the same, poor customer service.

that I think likely you can outdo Google customer service, haha.
