There was a story recently about how large landlords use salary data to raise rents. If they see you got a raise, they’ll increase your rent accordingly. And pretty soon, retailers will do the same. Your personalized price for a gallon of milk at Walmart will reflect your annual raise. I love living in the future!
Large institutional landlords use Equifax data, TWN, and other 3rd party financial tracking systems to dynamically price renters across the board; new rentals, security deposit, renewals, etc. These are pricing strategies insurance companies use to their advantage, often partnering with landlords to ensure they're getting risk-reduced renters.
Presumably this also means if you don't get a raise, they don't raise your rent as much, knowing it would make you more likely to move. They no longer have to guess about your ability to pay.
