Here's some nice new tile, new hardware, and a brand new toilet.  

Which in turn mean for net income on average, which in turn means my wallet gets fatter.  

And no dont do pink tiles becasue that is what one person wants for their 7 year old daughter - that is too limiting.genrally people want clean and comfort and ease - so if one item is not going to look clean with usual wear get one that will (usually black shows the dirt, as does stainless) - an as has been said, the inexpensive touch ups like nice hardware, a better countertop finish that wears well are the things you will want - think back to your life as a renter to help.

Fortunately I only have one house with a size filter I can't buy at a hardware store.

My advice is not to waste your money on testing clean with bleach water and buy a mildew mold suppressant from hardware store it's a chemical you put in a pump up sprayer keeps mold from coming back if on a painted surface get a fungicide paint additive and repaint area.

I've had tenants use Google wallet.

If you are right - that they took advantage of you - you will always feel ripped off and the taste of your purchase will continue to be bitter in your wallet.

i kind of want a service where people dont have to create a special account just to send us $40 one time (assuming they dont get the house).I think google wallet will work if they already have a google account. that's free and they can send $40 through their email as well.I hate to inconvenience people by telling them "go to cozy (or erentpayment), create an account that you are never, ever going to use and pay the screening fee".

now where did I put my wallet... 

The result is that getting trained in Hardware and networking course, one can be a technician, technical and also system administrator.
