Regarding materials, it's not just the units.

As a GC I can advise try to retain control of your finishing material orders (anything where you need to make a choice ((tile, flooring, lites, faucets, tubs)) vs. construction materials (2x4s, mortar, shingles)) because we get those discounts on the finishing items and we keep them!

What information or materials would I need to file one?

Not saying I would abandon this if I can't qualify for the material participation, but it is a factor.Any input is much appreciated!

Even if the bias isn’t political or socio economic, writers NEED something to write about, and if there’s no new and thought provoking change in lifestyles, let’s promote one we want to be true.  

The labor and materials cost varies widely in different markets.

An idea we have is, I am burnt out from W2 life, and wife makes great money (+$300k) , and I could take the year to repair/renovate, manage, rent, repeat the units in the MF qualifying for REPS status (50%, 750hrs, material participation, etc). 

"We are sorry that we cannot continue this insurnace therefore your policy will not be renewed...Material increase in hazard as evidenced by the fact that the residence is not owner occupied as required by our policy".

I am wondering if anyone would recommend any real estate investing courses, podcasts, books, or any other educational material that has helped them in their own career? 

I’m sure my post will be drowned out by a bunch of turn key operators, Realtors and lenders promoting markets with C/D properties but hopefully you will take some time to consider what I shared because most who focus solely on the BRRRR method work harder, not smarter in their real estate business.
