I had a new 4-plex being built in Point Loma while I was living in Cabo San Lucas. CoSine Real Estate not only went the extra mile to coordinate with the contractor to handle the final construction issues for me, but quickly filled the building with great tenants.

I rented a property that Jeremy managed and he's great! Exceptionally professional, always prompt and courteous, and a true pleasure to work with. Not only would I work with Jeremy again in a heartbeat, I'd also recommend his services to friends as well.
