Full service property management would have been a great asset to save time and headache.

Quote from @Tramaine Robinson: @Chris Bounds you still retired?

These can be fairly automated for you as well to help save you 10% which on 2 units could be well worth it. 

Direct access to MLS data, multiple solutions for sellers (off market cash deal or listing), ability to rep. yourself on your own deals (saving on commission), and of course, education & networking.Having a license costs $$$ though.

Do you have a nice amount saved up for the activities you enjoy(I assume yes given a 30+ year in Tech plus you mentioning making lots of money already in real estate).If that is the case, what are you looking to achieve now within real estate?

A massive transfer of wealth in the next 4 years: 40M Boomers are retiring.

While every IRA must have a custodian creating a special purpose LLC can allow you to bypass the custodian when making investments and performing transactions which can save time and money. 

You have paid for that monthly savings on the front AND back in that case. 

I listen to people who are doing what they are saying, with their own hard earned savings.
