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. 

With setting up custom rings you do not have to even look to know it is a call to your Google Voice number.During regular hours you can have it forwarded to your cell or office phone.  

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.

Only issue I'm looking into is max number of unrelated individuals in Renton, haven't found code for it yet, but most cities seem to allow only a max of 4 unrelated individuals to a house.Cool thing with this method is I'm still close to Seattle, and have all my living expenses other than food and cell phone paid for via the rents. :-)

Sure, there may be some who have to fight with the credit bureaus to fix errors, but I doubt that a credit report that you would deny a tenant based on, would be that big a mystery.For instance, judgments for cell phone and cable bills, or one for a previous landlord.  

Most apartment buildings have phone numbers on the internet, so I call those numbers to verify, not the cell phone number a tenant gives me.

I will add though that landlords are also required to have keyless deadbolts or similar device on all exterior doors so a tenant does have the ability to restrict enterance to the property while they are home

Whats nice is that there are NO balconies so people arent outside on the balcony talking loudly on their cell phones.

I ended my contract with AT&T cell phone and internet and uverse.

He and I get to talking and we end up exchanging cell phone numbers.
