Financing multifamily unit while occupying one unit

[Wesley Robirds]

How hard would it to be to finance a four plex while occupying one as a first investment and would also be my first home loan in general? The more information I can get the better on the possible down sides up sides or issues anyone sees with this plan also advice on where to find this kind of financing would be great I was told I could possibly have 75% of the potential income to be considered for the loan and the last off my w2 income.
