Rental income from a rented room in primary sfr to qualify?

[Joe P.]

If I rent out a single room in my primary home can I use that rental income towards my 2 years of landlording experience and use the rental income to help qualify for a mortgage on another house?  I am interested in house hacking and buying a new owner occupied place every year or two.  It seems as though if I buy a sfr I would have rent it out for two years without living there before I can get another house unless I can qualify for a second mortgage.  Am I correct?
