I do see many investors incorporating a similar strategy with new construction builds, heavy rehabs, or in instances where the property was bought far below market value (usually a wholesale type transaction).

However if you are getting the buyer yourself and need an agent to draft paperwork and work as a "transaction broker" - I charge 1% or $3000, whichever is greater. 

Without knowing your transaction history I stand by what I said.

Being a transactional RE broker in my first 15 to 20 years nights and weekends were a must to be a top earner.

If you think about it in any industry less transparency and more friction in the transaction will increase fees/commission vs reducing them.I like the idea as an investor of having different agents, a team of agents maybe 3-4 bringing me deals, but I think less of that will happen now as all will have to have you sign some kind of agreement up front. 

What is your source for 99% of transactions are above 2%?

I do not have experience in commercial real estate transactions.

Don't trust what ANYONE tells you about a market without solid data to back it up - this includes claims about how many transactions they've done or a single example (that's often from several years ago). 

This brings me to now, I've taken this approach and have used my own money in lending, but am also bringing in friends and family to take part in these transactions so they can earn way better returns than with CD's.

You will have a leg up on the language, transactions, inspections etc.
