By diversifying, but still investing in the most promising deals, you limit the possibility of a devastating loss without limiting your upside.  

Lincoln Place: Still somehow in city limits but more suburban neighborhood.

I limited each season to 20 people. 

But unlike a Roth, there are no contribution limits.

The city wants to tear the property and surrounding properties down Zillow said it’s worth 38000The city offer me 13000.I could use some adviceHard to give advice with limited information, but as a general rule, the longer you wait and the further down the line their project is the more valuable your property will be to them.Zillow (and all automatic online) estimates are very unreliable, so don't base on that.

Most institutions have a 70% limit. 

So, you are not at limiting your self when buying a new property.

Credit cards have the same limitation on the amount you can borrow and will likely end up costing more than private lenders.

I am okay with limited cashflow while I'm in my prime W2 working years but not negative. 

That limit was recently bumped up to a $100M maximum.
