I have experience with cellular concrete in a commercial application as mass-backfill (15,000 cubic yards) for a newly constructed building where existing soil bearing pressures were poor.

They seem so complicated but if they work for you more lower to you  This is what a properly set up funnel, that has a great lead generation system to feed the funnel gets you:We bought this green house now worth $320K, for 10 dollars.While you are scouting the MLS, or Zillow, and doing a search  spending time and effort relentlessly trying to find a deal, and when you finally do find a house, you probably pay market value or close to it....we do absolutely do nothing, no time, no effort, no money, and the leads poor into my inbox, When dealing with true motivated sellers like I do, there is no need for funnels.

The positive thing here is that there isn't a poorly written lease that you have to adhere to for months down the road.

With the way landlord / tenant regulations are going, I would bet that it will be revoked.

That’s the best bet.

@Daniel HanWhen asked about what could go wrong, I mention rents not being paid, poor underlying financials at the outset, unexpected expenses, to name a few. 

This is probably a dumb question but have you read Rich Dad Poor Dad - by Robert Kiyosaki?

Seeking out poorly marketed rentals for owner financing opportunities would be the other faster option...maybe checking craigslist or yardsigns in the area you want to buy.  

@Peter Amendola - Hey man your best bet is to either plan on working remotely for a week or two up there after you close, or take some vacation and go up there and get it set up the way you want.

Some of it is finished and some is not and most in poor condition.
