If you do buy a pre foreclosure and follow all the rules and sell within 36 months any profit 80% has to go back to the original owner  who was in foreclosure.Since I made living doing foreclosure rescue prior to this . the new laws removed that activity from my business..

Centralized Document Storage with Access ControlHave a secure, centralized system to store, organize, and share all company documents (e.g., contracts, blueprints, reports, scanned records, etc.) while managing access permissions for teams and individuals.2.

A 1031 Exchange is also known as the Tax- Deferred Exchange, which allows the different shareholders as well as different depositors to reinvest the profits that these people had acquired as well as earned, most particularly when it comes from the different financial transactions of the property that the investor had advanced without acquiring different taxes from the government.

Can you net a solid profit, without having too much risk?

Nobody knows so what I do is making sure I'm profitable, even at rock bottom rents.

You'll need to make sure the ROI spread is large enough that you can still turn a healthy profit if you have to sell under what your projecting for ARV. 

What makes it slow in this case is that you don't really start seeing real cash flow until after year five but it's more effective than rentals in that there is little to no maintenance.Sure you can live in a home while fixing it up with the intention of selling it for a nice profit later but I think many people are already doing that and the buyers of slow flips now also have that opportunity without having to qualify with a bank.

Some investors have found that working with the right team even in challenging markets can be a pleasant and profitable venture.  

Fully occupied, the property grosses $5,570/month with $4690 net profit after expenses.

Quote from @Evan Polaski: @Jay Hinrichs, while I wasn't going to call them MLM, I did attend an Armando Montelongo (A&E's Flip this House from mid 2000's) seminar at a hotel conference room in 2007 or 08, which was the free funnel to spend $1,500 for a three day seminar or $25,000 for an in-person mentorship.I have seen similar promoted with Christina and Tarrek from Flip or Flop more recently.I didn't start realizing how profitable education can be until the last 5 or so years.
