Like the fee simple estate, isn't that just basically becoming the owner of the property?

Simple. 

The best way to explaining this is for you to download an IRR calculator spreadsheet or build your own simple one and play around with one.

My 2020 goals is simple and I want to buy 2 multi-family properties.

I secretly miss the days of notebook style planners, but I also really enjoy technology and keeping things simple with electronics/apps.

I don't quite follow your story, but real estate and all sorts of other disasters often boil down to one simple thing: not enough money in reserve.

I am currently looking for properties in Manayunk/Roxborough as I see a high rent demand, relatively lower prices and a good opportunity to do simple cosmetics to outdated properties. 

If that doesn't  do it for you, it should be fairly simple to google the calculations and put them in a spreadsheet you put together.

You can purchase a property yourself using your capital gain, you set up an LLC to take title,  then you self certify at the end of the year designating The investment  as an opportunity zone fund  It’s actually a pretty simple process.

Try collecting on that judgment--it's simple in theory but definitely not easy.Go ahead and put whatever you want in your lease (as long as it's non-discriminatory) but also make sure you take steps to make your units as tenant-proof as possible.
