And they'll get a cell phone and you can text them.  

@Charlie Fitzgerald, unfortunately, i only have her cell numbers and her email address.

If the problem is really bad, I would be willing to say consider a "car wash allowance" of say $10 a week which translates to say $40 a month of rent reduction...to me is easier than a car frame or self car washing.Speaking of particular tenants, I once had one who complained that her cell reception while inside is 2 bars instead of 4 bars as if this is something I have any control over. 

I know, I was a cell biology grad student.

We do not have such a thing since we use our cell phones for personal and landlord purposes. 

We only manage 2 ourselves, and when we're out of the country or on vacation where cell phones don't work well, we ask a family member to take the calls and give the tenants their number.  

I would be signing necessary documents/Lease at thepoint of my arrival because i have got no printer and scanner herewith me.HERE ARE THE DETAILS NEEDED***Full Name:***Street Address,City,State,Zip Code:***Cell & Home #:***Total amount for move in: Kindly get back to me with the details requested so that i can getit across to my father to issue out the check for the deposit andmonth rent upfront asap, with that you can hold on the place prior myarrival.Thanks for your co-operation.

Classic mistake is the owner will hoard cash and live fat for years and make good bank.

Even if it's actually true, why should I care when my mortgage company, cell phone provider, etc doesn't care if I lost my wallet.

Everyone has a cell phone now, so unless it's required by law, I'd just put in cable and I bet no tenants would complain about that.
