Instead of physically to your property to help troubleshoot, you could have had a quick video conference (cellphones) where you could ask your assistant to operate the door entry, while you see it on your cell phone.

My house Is paid off and the rent covers all expenses you mentioned plus electric, our cell phones, internet and auto insurance.  

Typically a contractor provides their own tools, which in the case of a property manager means their own vehicle, cell phone and computer.

My gf & I have both had our current cell phone numbers for over five years each & have been at our current address for over two years...

sell your car, watch, cell phone and blood. 

In an economic downturn, nobody cares about your ego, your multi-million dollar producer status, your new BMW, or if you look like a mover/shaker talking on a cell phone in your marketing photos...let me repeat that: NOBODY CARES!!!!

These entrepreneurs’ already depend on cell phones exclusively.

My tenants know where I live, they have my cell phone number and I see them around town every day.

My history is in cell phones, 5 years in retail (including management) and about 5 years being self employed buying and selling.

@Elijah Brown congrats, love your story man - I also closed on my first deal while out in the field for IBOLC at Fort Benning last summer - can definitely relate to the excitement of sneaking a cell phone check to find out you are now officially a real estate investor!
