Reviews

Former tenant·Over 2 years ago

4G Realty, the old owner as of 2021, was awful

Pros

Generally responsive via email, even if nothing was done about an issue in reality. Good rent in a nice area, and other building neighbors were/are great.

Cons

Gave an illegal and confusing, convoluted lease and tried to illegally raise stabilized rent. Did not clean the place when we moved in. Lied about fixing issues and never got back to us after our apartment flooded (and this was before the citywide flooding), so it will likely happen again. Did nothing for mold problem prevention. We finally put in a lease violation with DHCR and the next day found out they sold the building.

Advice to the owners

Fix your issues with your buildings and take the health of your tenants seriously. Oh, and stop illegally trying to destabilize apartments!
