I have lived here 2 years now in a 1 bedroom. This property was just purchased by Knightvest. I enjoy that it is quiet community, the availability of living in townhome setting and the pool area...However as my lease is up I now need a 3 bedroom and I am having trouble getting returned phone calls or emails in regards to my supposedly new lease which should be in 3 weeks. I am afraid to hire movers only to be told my move in date has again been changed. They are not honoring a special they offered my roommate when he spoke with the leasing agent.
Just very disappointed they don't seem to care about keeping me as a customer.
I would like to stay here but all these negative remarks and no response from my email or them answering the phone has me very nervous.
