Are you only searching to expand in Miami Gardens or all of Miami / Broward?

All of my projects I bought the land first with cash, then used it as part or all of my required 20% equity in the project.  

You can buy a home, one that one needs work or one that doesn't and rent out your extra rooms to recoup some or all of your mortgage.

Putting a single number on a property is a little flawed in itself when you factor in flexible/stubborn sellers, adequate/inadequate marketing, etc. but a single number is required by most lenders.

Currently the Florida Supreme Court is hearing oral arguments on the Bartram ruling.

The down payment on any property would use up a good portion or all of that amount leaving you with very little to work with. 

For the most part it  seems the rent control bills being pushed these days (at least west coast) are somewhat less draconian than earlier designs,   so maybe possible to do OK with it in place as long as you take most or all of the allowed increase annually and don't fall behind on capital maintenance.     

If they disagree with your strategy then ask if they would waive any or all fees for permits to add a parking space at the front of your house.

The strategy I am pursuing is buying multi-family units that are underperforming and improve the property so I can raise the rents, making that property more valuable so I can refinance and get most or all my money out of that deal so I can use it on another.  

The seller can carry back part or all of the sale price.
