Most college kids don't have anything saved so you are building the right away.

I’ll give you that AI can drive machines that one day can build houses to some degree.  

The sharks at the meetups will be obvious avoid them and build relationship with everyone else.

I started in financial planning at 24, started my own firm at 26, got my CFP at 27, sold my firm at 37, while building up real estate along the way.

Your understanding of the depreciation recapture process is almost correct, but there's a minor error in your calculation.When you buy a house for $300,000, with $100,000 attributed to the land value, you have $200,000 allocated to the building or improvement value.

I took on 4 buildings - 2 of which were highly distressed.

Unless you also had plans for new builds in the near future, in my opinion, there's much better investment options available in the immediate area

My question is while I was looking on redfin, I found a big 14-unit buildings that is for sale around $3 Million.

The main thing you will need to do before renovating any house or building is to make sure you have a good team in place (an administrator or a licensed care home manager).

You don't want to rush to partner just to get your next property.If I was new again now and didn't have the capital to get my second one, I would go to every meetup in my area, meet other investors, and build relationships.
