Mortgage Cash Reserve Requirement

[David F.]

For a landlord who has properties that are finance and have been rented out for 2 years and who is applying for a mortgage to expand his/her portfolio, is that landlord required to have 6 months cash reserve on hand for the new properties, or for the aggregate of all the properties in the portfolio? Let's assume for the purposes of the discussion that the existing rentals are very profitable, 100% occupied.
