You might not be able to find a single educational source for all of it.

I have owned one single family home for about a year, which I bought with owner financing from a man who owned it as a rental, and I am currently negotiating on a four plex with the same seller. 

I know many say it’s too much of a hassle but I was an on-site leasing agent before for a 12 floor apartment building across from a large college so I have had SOME experience with it.I’m currently a single federal employee hoping to cut some expenses and do more in real estate.

I've secured funding for single family investments, but have yet to pull the trigger.

Single-family?

I am in the process of closing my first single family deal.

I'm always nervous about single-family just because the scale is so small that if anything happens (replace an AC unit - $3,000) you wipe out a whole year of cash flow.  

Both participant accounts can be invested in the LLC which would be deemed a single member LLC since just one solo 401k plan is being invested in the LLC. 

As someone who also had a real estate background and got into notes I would suggest to start in single family and buy a performing note first.

All single families, all in Missouri.I'm about to have a 5-unit apartment complex under contract.
