My questions is, which size floor tiles should I use, 12 inch or 16 inch?

Likely not immediately, but could it inch us toward that slippery slope?

It could be that the alarms are mounted within 12 inches or so of the ceiling on a wall, and all wires fished up from below (or from receptacles in the walls).

Having double the cash flow in property located elsewhere could buy a lot of hand off management though;) imagine a trip to a warmer climate once or twice a year to visit your property during Jan when there is 6 inches of snow on the ground.

This way you are inching toward increases but not slapping a good tenant in the face.Also when I do rentals and they move in outside of the first of the month I just prorate the rent so they pay on the first.

The house is built on a slab with city water running underground in a 3/4 inch copper pipe.

I visted the home myself and walked through every inch of the house.

They are looking for you to create a unit of measure for the permeable of the soil in MPI (minutes per inch) by filling the hole with 12-18" of water and after a certain time period measure the waters depth to see how much the ground has absorbed.

(The thinner the boards, the more expensive. i.e. 5 inch 3/4 is easier to rip up than 2" 1/4 (3/4 inch wood).

So its off to HD to get 1 1/4 inch screws.These screws seem to be the size used with every 4 in metal electric box in the nation, but aren't really the same at HD's #8-32s pan heads.
