First, verify the phone number as a business number and not a friend's cell number. 

They all get my cell phone number and the office number with the extension to the property manager and emergency maintenance.

I think right now is a good time for you to go on a 7 day cruise where your cell phone will not work. 

As I’m driving in Mass Pike with no traffic which is beautiful having the road to myself  and feeling like a road warrior (HA) i noticed cell towers after cell towers after cell towers on all the building and houses and churches.

We have programs that we readily pay your; grocery bill, rent, cell phone, internet, spending money, health insurance, Rx coverage, day care AND to boot not only do you NOT have to pay diddly-squat in income tax's that the rest of us subsidize (pay) for you but we even send you a big fat check each year if you have kids. 

My portfolio is small and I self manage, so I am still able to give my cell to all my tenants.

They may need to start posting cell phone numbers so investors can get in touch with them. 

I also notice cash for gold and prepaid cell phone stores in questionable areas.

lol with real estate, I am always working... even when I was in my honey moon away in the mountains(I was in the middle of a deal, my new husband had to drive me around to find internet and cell phone receptions) He has planed our honeymoon months before the wedding but he changed the honeymoon plan so I can have my deal.

But what stuck with me also was the statistic on cancer meds (where a huge amount of pharma development money is moving).
