Is it just that much of a killer deal that you can't resist?

Im thinking I have to rip up all the old tile and replace the drywall around the shower and install new water-resistant drywall.

Roaches can live for months off wall paper paste , cardboard, anything ... you won't be able to starve them out but if you want to get rid of them useDUPONT ADVION GEL BAITThey can't resist it then they die, their friends eat them, and then they die too :)It will work.

Is it any different for a bay window - should it be expected to resist the pressure of people leaning against it ? 

  $50.00 less per month over 12 months works out to $600.00.Also, hind sight being 20 - 20, you might have met less resistance if you tried to bump them 8% each year. 

Get something with a 12 mil wearlayer WITH A SCRATCH RESISTANT FINISH like Aluminum Oxide.

Most people who grow don't want anyone in the property so I think you will get resistance but you need to keep pushing.

If they resist, I'd give them a 3 day notice to cure or quit.

You can get some good stuff nowadays that looks like hardwood but is water resistant, etc., making it more tenant-proof.Oh, and my issue with the recessed lighting is trying to replace the bulbs. 

I am also working on an SCRA article/video, along with a "are military towns REALLY recession resistant" thas t discusses pros and cons to military tenants!
