Financing rental property

[Horacio Gutierrez]

Hello, I heard that banks want you to have 6 months reserves to be consider for you borrow money for a rental property. Say I have 4 rental property already with banks loan with postive cash flow or break even and when I go to the portfolio lender for my sixth loan for rental property will i need 6 months reserve for each rental property or is it only 6 months reserve for the home i would buy the bank dont care about have 6 months reserve for the rest of rental properties?
