Contractors are in high demand right now and some trades like framers are in short supply. 

This time we're buying from a contractor supply house rather than from the big box stores.

In prior years, I listed them as "supplies" and split the cost equally among my active properties on Schedule E, but now I am wondering if they should have been "assets" instead.

The house shutoff (versus the main shutoff) should always be after the water utility meter (referring to before and after from the supply side). 

As with any market Supply and Demand play their role.

@Bryan ChampHere're a few points to consider/analyze:1) Just like with multifamily, you need to evaluate supply and demand in the area2) What is the MHP size (in other words, how many pads)?

Cordless and Battery powered for those projects where only a small amount of paint is needed and power supply is an issue.  

In California the max deposit that the contractor can ask for is 10%.For me, it's most common for us to fund work on 30/30/30 schedule.  30% at the beginning to order supplies, 30% at a midpoint, and 30% after final walkthrough.As far as who pays who and when, it depends on your lender and scope of work. 

. $1050 a month is too much for most, you want to find an equilibrium price where supply and demand meet for max profit. 

Not mentioning your budget, making sure the bid separates labor from supplies, paying up front, etc.
