I have 18" light porcelain floor tile with a light colored grout.

Have you tested vs. other colors of signs to see if they pull better?

If you can get the smell out but not the stains, refinish the floor in a dark color to help hide the stain.I have not found Nature's Miracle to be of much use,

I had read on another forum (sure can't find it now) about some landlords who had amazing success dying carpets a more tenant friendly, darker color (I'm thinking brown).I could absolutely replace it with some cheapo HD entry level stuff.

But I will second that motion David.

I wonder if anyone has any experience with cameras with motion sensors?

Second that motion.

What they're doing is a horse of another color.

The motion or application shall be made with at least 30 days' advance written notice to all persons who may be affected by the order, including lienholders, and shall be granted unless the interests of justice would not be served by such an order.

An owner who is really motivated to doing everything needed to complete a short sale will increase the odds of a sale ten fold from the seller who is unmotivated and just going through the motions.
