I've been running strs in the Poconos area for 5 years now, one of the hottest markets in the US.
I no longer tell people it's easy money. I tell them it's a full time job, housing prices have doubled, and competition is so high that I've seen houses come onto the market 2 years ago, rent for 2 years, now they're trying to sell and ditch them.
I used to make a good living without any real knowledge or effort. My houses looked like prison cells. I didn't have to hire an interior decorator or a professional photographer, I didn't have to make bedrooms look different from each other, I didn't need a hot tub, or pool table, or arcade machines.
I see people struggling to enter the market now and I wish them the best, but they're facing people like me who have evolved dramatically and spent the last 5 years perfecting their craft. Unless they can quit their day job and devote themselves to it, it's not going to be pretty!
