I’ve completely rehabbed multiple primary residences trading up each time.

After that, mom did not give tenants permission to paint.But then there were these college students who didn't care about rules like that, and they "painted" - I have to put that word into quotes, because when you see what they did, calling that painting would offend the members of that trade.

Specifically the current competitive rates for new construction trades and materials (e.g. foundation, framing, plumbing, electrical, drywall, trim carpentry, painters, tile work, brick layers, roofers). 

I drove out there ASAP with my chainsaw and trailer, apologized, cleaned it all up really well for her and we traded insurance info.

ROI,  means return on investment and does not consider down payment, equity percentage, or if funds used for investment were borrowed, stolen or gifted or traded for equity.

An IRA is an individual account and is not sponsored by a business.A business, for the purpose of sponsoring a 401k, can be any type of trade or business that is carried on.

Did my research, found a few sources and built up a portfolio of publicly traded REIT's with a small modest size of around $20K (and growing of course) producing div's. 

Short term trading and refinancing RE is Expensive on multiple levels.   

And outside the exchange you now have a note for $80K which you traded $80K for so it is tax free except for the interest payments.2.

You are not wrong that the margins are thin, if you follow any publicly traded solar leasing company you can see why they call it the “solar coaster”.
