Also, rather than taking a large amount of money and investing into one single directly owned property, I can split it up into much smaller chunks across many different passive investments.

This could be a single person who has their brokers license or a larger brokerage like Keller Williams.

I have had single women rent the place and then bring in their deadbeat boyfriends as live in until they are caught. 

I think that is their largest single asset/stock allocation actually too. 100k sounds lofty.

Selling plexes isn't quite single-family residential, and it isn't quite commercial.

Only luxury single family houses will be built. 

For your primary residence, you can exclude up to $250K (single) or $500K (married filing jointly) of capital gains if you’ve lived there for two of the last five years.

Please see the rough numbers below :Tear down house price 350k,Construction cost 165 sqft * 2 build=627k too much for the land unless your exit is 3 million. don't reinvent the wheel. no single family home builder is paying 300k for land. that's miami florida prices where I live. we buy land 50k and under in Columbus Ohio. keep land at less than 10% of after built value.

Single family long term rentals has been working for me. 

We have couple turnkeys, and couple of BRRRs that we did so far (all are single family residential properties with long-term tenants).We are interested in exploring commercial real estate, and wanted to get all of your help in getting started.
