I feel like the negative reviews here are for a different management company. They dont match up at all with any experience I have had. I've rented all my life, and I've never had a better experience than here. Their response to any repair issues I have is quick, I mean, I can place it at midnight and get a response at 4am. What is that? They have been incredible with anything I need, our property is well maintained, and not a single time have I had to bother them more than once for anything. I love everyone I talk to, they are so helpful and responsive. Honestly the best renting experience I've had. Love my rental!

I gave four stars only because the property wasn't renter ready prior to me moving in. However, Paula has been very easy to work with. Any repairs needed have been made in a very timely fashion! In fact, my water heater was old very old and not allowing the water to stay hot more than 10 minutes. Not only was it replaced but the company came out on Christmas Eve to do so. Although, that was not so good for me.but the fact that my property owner and this management company took my concerns seriously was appreciated! Not sure why they're getting such bad reviews? I can personally say I appreciate them very much! Hopefully, this will remain a positive rental experience!

We've been contracting with Cornerstone for more than 5 years. I've worked with many management companies over the years, but Tom and Cornerstone are bar none the best in terms of responsiveness, professionalism and ability to deal with complex site problems. Cornerstone manages our property for a relatively low rate, and yet still goes above and beyond in terms of site work, emergency response, tenant relations and contractor bids.

They even spent a great deal of time dealing with our insurance company, ensuring that we got a fair settlement. If you want to protect your investment and be assured that the rent money comes in and the tenants are safe and well-served, sign up with Cornerstone. Tom is a real professional.

Never got a call back to clarify the reason for denial, even after appealing. half a million liquid in a bank account and credit rating of 740. Which they sent a letter verifying that that was fact. Waste of money and of course I know, no refunds on apps. let alone the fact I drove from Palm Springs to view the space, the agent blew off our appointment no call back or explanation, still I was cool and really interested in rental. Sucks.

I was a property owner and hired this company to be my property manager. It was the worst experience and makes me not want to deal with property management companies. They have gone through at least 5 different property managers in the 2 years that I have been with them. It has been 7 months since the property has been rented and their attitude is that they don't care. It went from summer to winter unrented and they didn't send anyone to check and make sure the property was properly winterized. Needless to say a pipe burst and the whole place flooded.

I then was charged material that I did not approve and since they had changed managers once again they told me there was nothing they could do. I definitely regret ever hiring this company and would highly suggest anyone looking at them be prepared for the worst.

I have no problems with this company. It took two days to get approved and its been a month less than a year. Not sure why they have so many bad reviews. They are professional and have reasonable price rent.
