How to finance my next live and flip/house hack

[Jacob Casarez]

I am just over a year into my first house hack/live and flip deal. My brother and I owner occupy the property and rented out 3 rooms in the home for a total of $1,250/month utilities included. Almost cashflowing out the mortgage of $1,371. We would like to move out of our existing property into a new owner occipied house hack. Therefore renting out our two rooms and cashflowing out handsomely on deal one. Do we have to show months of rent rolls? How can we do this? Any information helps. Thanks!
