Quick math for the rest of you out there: That means they paid 1000 in 2009 and now pay ~3500 in 2019.
Also, yes, I feel you there. Our rental agreement states a mandatory 10% increase if you rent from year to year. I've no idea why the company is this stupid though. The rents around us are falling or staying steady these days. So we just move to the block over every year and the old place stays empty for 3 months before then being rented out for the same or less than we paid. I'm sure there is some tax thing involved here that makes it so they don't have to care all that much.
Also, yeah, we don't have a lot, and we can just move houses in about a weekend in my 4-door.
