This is considered self promotion and is prohibited in the forums.

You could consider airbnb but you would need a good STR manager for this and I'm not sure the margin would be worth it if you don't self manage. 

I self manage my properties, and that's my preferred method.

May do other areas but not yet because I self manage.

Are you going to use property management or will you self manage?

I accept a lot of those issues are both self induced and partially inherit. 

With a little self reflection, you will begin to learn your strengths, weaknesses, limitations and preferences.

Plus, you are probably talking $1,500,000 to 2,000,000 purchase price to buy a 20 door apartment with $300,000 to $400,000 down... so while I imagine that thought was just conceptual... start small... 1 property... maybe it has 1-4 doors... its often more about what you can find, that is at a good price, that you can afford, that will rent the best.We are at 40 doors in 3 years, and it's a number we have been trying to hover at, because it is a size we can self manage, and that is what we are trying to do for the moment.
