How to maximize your buying power with a line of credit?

[Chas Drost]

So I've taken the steps and established a line of credit w my local bank.  I want to buy some housing rental properties. 

My question is, do I purchase 1 house at a time with the line, then refinance into a mortgage and rent?

Or do I use my line as the down payment portion and try to buy 3 or 4 houses at a time?

Trying to figure out how to maximize my buying power?
