Is it worth it for a couple hundred dollars? 

It has no life: it is simply an expense that is necessary to do the rest of the work, so you can write off the $25,000 demo & disposal cost immediately, then depreciate the rest.I have heard some investors will break out the cost of individual materials, such as roofing nails, and say those only have a useful life of 10 years and depreciate that component at a faster rate compared to shingles, but most of my projects are too small to bother with a few hundred dollars worth of nails.

You'll be able to walk through a house and go "5k for this, 2k for that, 3k here...etc"Till then, you could visit your local suppliers of cabinets, granite, flooring, roofing and see what kind of prices they charge including installation.

Our first duplex had what I am sure would have been considered mediocre numbers had we asked for input from BP, it more or less was a couple hundred dollars in cash flow/month when I did the model.

Walls, ceilings, cabinets, doors, shower, etc.

Capital Management manages a few hundred units in Tacoma and surrounding areas. 

If the flip only takes 2-3 months, you would probably pay a few hundred in interest but also get a nice profit. 

I suppose your area does play a part (especially if termites are bad) but I do remember a BP podcast where a woman had invested with her significant other in Salem, MA and they had at least one property that was many hundreds of years old.
