@Ben Granja - Depending on the bank, they'll most likely give you up to 80% of the lesser of the value of the property and the purchase price. 

(yes I can get data a recent as yesterday, no i will not provide it, i do have some semblance of a conscience, so please do not ask)My pricing is negotiable depending on the county and your requirements.

completely depends on your state/city laws.

I want to know the cost to design and build  (3 bedrooms 2 bath) two 10 units   5 up and 5 down building in clairmont, Florida and how many square foot of  land i need, I got a group of investor to get this done Average rent depending on design, 1400-1750.

Depending on whether you have plumbing and wiring chases, doing it later can be disruptive to the units below, like cutting out a chunk of wall.

It really all depends on your goals and what you want out of it.

Depending on how much your looking to tie up why not partner with a flipper, you fund the deals and take a steady interest payment.

It all depends on the specifics of the property and the level of build out.

Congrats being debt-free @Elsa M.This will completely depend what type of assets you are buying for what price & terms and who will be managing it. 

But it all depends on your goals.Take this advice with a grain of salt.
