@John Zhang If your wife qualifies for Real Estate Professional Status (REPS) and materially participates in managing rental properties, there is no limit on the amount of rental losses, including depreciation, that can offset your W-2 income.

I do have a third goal, but too much will happen by the time my second goal materializes that my third goal will likely change drastically.Also, I tend to find myself wanting to ask market-specific questions to agents/lenders/investors/contractors/etc. a lot.

Sales Tax Breaks: Construction materials and services may be subject to lower tribal sales taxes—or exempt altogether.4.

I know lots of installers don't do it, and I personally prefer the unimpeded look, but anything installed outside of the requirements of the material is probably going to be limited, i.e. the insurance company is not going to pay you because the material was not installed according to flooring requirements. 

When I first got started I didn't officially join any coaching programs, but I did buy the materials at mobile home university.

I know they are compensated per unit for the inspection, do you think it would be an issue if I just registered a fifth unit and made sure it met all the requirements?

The changes that have occurred in the past year is making sure the comps are truly there, getting the material costs down (or accurate) number with changes all the time on costs. 3.

I'll go with @Greg Scott line set metal cover idea and @Chris Seveney idea for painting the copper white.Thanks folks!
