“They did a fabulous job on a big renovation. We called them at the last minute and they were able to be there immediately. We got a good price with them. They were on time, they did a great job, and the girls in the office were great.”

“They assist you and keep an eye on our properties. They give us reports to make sure we are aware of current activities. I send them an email, and they take it from there, providing me with a proposal. Should I have any questions, they answer. If I need to cut costs, they can help me — they'll send us pictures of certain things that need to be done for our tenants. They are our eyes and they know the property more than you do, so they are very helpful.”
