Don’t be afraid to fail and if you do treat it as an education! 

In a typical home sale a sewer line has either failed or not failed.

I have seen many REIAs fail because the leaders set them up to feed off new investors.No, this is not fair.

You can make either work or fail as an investment.Personally, I would think doing a remodel from a distance would be hard.  

Such a simple concept so many fail to do.

As far as making too much, 80% of agents fail in year 1 and 80% of those left fail in year 2.

Gurus who teach pre-foreclosure investing often fail to mention "where" to get the money to cover back payments if one does not have the money out of pocket to cover the debts.

The main component in a CFD is the forfeiture clause which states what happens if the borrower/buyer fails to make timely payments. 

I imagine that the legalities are complicated and if the building fails to cash flow at the expected amount or the owner needs to sell and cannot get the assumed equity out of the building then the investor might be unhappy.

It's up to the tenant to ensure they have sufficient funds, if a Cozy payment fails or a check bounces I then charge the tenant a fee (assuming this causes it to be late).If you're really concerned you can take what @Jonathan Cope does one step further and require payments on, say, the 25th in your lease.
