Conventional Loans on 2nd, 3rd, 4th SFH Rental

[Ned Outtadebter]

Loan officers lately tell me one thing, then call back "oops, I was totally wrong, the underwriter told me something else..."

Anyway, I'd like to get a straight answer from BiggerPockets:

I've owned/rented one SFR for five years now, with rental income exceeding expenses each year by about $5-10,000. I would like to purchase several more houses in this style, but I'm concerned with funding.

How long is needed to establish the second rental house income for use on a third rental house? Is it two years per house or two years per person for just the first house?

As I understand it, typical underwriters want atleast two years experience before counting any rental income. After that it's 75%.

Thoughts?
