The company name in the fine print of the lease is probably something generic like UDR or AMC or Essex or "Home Properties, Inc" or "Equity Residential". These REITs are brokers: they manage multiple apartment complexes in multiple cities in multiple states: http://www.rednews.com/2014/01/top-10-u-s-apartment-reits-as...
These REITs are constantly merging, acquiring and/or swallowing each other whole, consolidating into bigger and bigger conglomerate brokerages. The bigger they get, the more they can throw their weight around and control rents. Especially in "trendy" markets.
They tend to spam craigslist. They tend to require lots of fine print and have fees for everything, with contracts that are far too big and lengthy w/credit and background checks, excessive deposits, always always pet fees, and always at least a year when you sign the dotted line.
It's pretty scary what's happening in this niche: it's like they've figured out the trick is to steal any savings you might be able to build (rent hikes ~8 percent or more per year), thus trapping people in rental hell.
