Being an out-of-state investor, I've had to rely on property management companies. In the last 6 years I've been through 3 different PM companies. One larger firm didn't care about my property, didn't market it aggressively and yet charged extremely high fees. They also weren't responsive to my tenants or me. I tried two smaller firms and they ended up not being honest, transparent and one actually stole from me.
I was lucky to find Red Hawk. They set themselves completely apart just on their customer service alone. They ALWAYS answer the phone, they communicate regularly (discussing marketing strategies for my properties regularly); they manage the properties as if they are their own. I also like the fact they are transparent. I can log onto their system and see all of my monthly bills, current rent rolls, etc.
I've also partnered with them to buy properties. Jerry, in particular, has worked with investors for years and understands the needs. He is direct, honest, and a heck of a negotiator. I highly recommend them!
