This should be illegal. I lived in apartments like this as well, they would increase the rates for existing tenants while giving lower rates to new tenants. I’d also move out when they tried to pull this, just out of spite.
I have always heard that it’s cheaper to keep an existing client than to acquire a new one. Apparently these places don’t realize that. They don’t need to pay for advertising when they are filly booked up with people paying the market rate, nor do they need to do all the extra work invoiced in signing someone up or moving them out. I don’t own or operate a business, so maybe I’m talking out of my butt, but these people strike me as bad business owners who are chasing the wrong metrics.
I've very late to the discussion, but this seems relevant anyway -- The issue isn't just the cost of getting/retaining customers. Businesses don't charge solely based on cost, they charge based on what customers will pay. Existing customers also are willing to pay more to not have to move. If customers are willing to pay more, then it makes good business sense to charge them more. For the owner, having an empty apartment is the worst, so it's worth it to do extra work and give discounts just to get somebody renting.
It isn't nefarious, and you do your part by being willing to move instead of pay the higher price. It's all just the way the capitalist market works.
