With some damages you need to take into account normal wear and tear, or even depreciation, such as on a depreciable item like carpet.

This summer they asked if we could replace the worn out carpeting on the first floor before winter came, as there was no padding under it and it was the coldest room in the house.

I would have to fix it up a little (dog chewed up my baseboard) and probably replace the carpet.  

The remaining expenditures were paint $2K, carpet $1K and new appliances $1K.  

Supplies are like buying a big box of light bulbs or 9-volts or carpet shampoo solution for future use.  

I called to get the price and they are asking $150k each. 4 of the 6 units are rented for another 6 or 7 months and agent said should only need carpet and painting and the kitchens and baths could be updated so you could increase the rent.

Anyone in the Chicago suburbs who can give me just a rough set of numbers for things like a kitchen gut, bathroom gut and carpet and paint for a 3 bedroom 2 bath house?  

The carpet was still stained and she refused to surrender the key saying that she will leave it in the drawer of the apartment when she has a chance to clean the carpet. 

Some of teh REI talk about spending some more on upgrades (ie wood flooring versus carpeting) so it is easier to maintain  and less for them to damage.  

I have two condos in the same community, one of them I bought as a bank REO and I had the carpet torn out and replaced with tile (very common in florida homes) so for $5k + the $20k I paid for it, I got a place that appraised at $40k a year later.
