You will find resources here from blogs to pod casts and forums.

For some reason I thought a 95% would have a EC motor w/ mod gas valve, and a zoning controller could simply integrate into the units control board.  

I took time the other day and listen to my first BP pod cast.

WVBK did a loan mod and I got the property with zero cash out of pocket plus a loc to do the work.

My goal is to someday being invited on the bigger pockets pod cast, showing that if someone who works a 15 on 6 off schedule and 16 hr days can pull it off...anyone can.

As I said, many of the mod's in the market have pushed those rates down to 1% and 2%, so even from a rate stand piont, it benefits the lender, which is the same reason the legislation was created to begin with.  

Exactly, multitasking with the pod on is my jam! 

As @Gorden Lopes mentioned, fourplexes come in pods in Huntsville.

(from a Roofer) For a residence (duplex), it's probably best/easiest to go with an asphalt type material (as Eugene mentioned), like Mod Bit (Modified Bitumen). 

If in a residential neighborhood, and most of the houses have shingles... your flat roof may be just fine with using Mod Bit materials (Modified Bitumen).
