Questions- Renting my current home and buying another

[Michael B.]

Ive been on bigger pockets for some time now, learning a lot about real estate. I want to get into buy and hold real estate to build a strong retirement for the future. My family is ready for a new home so naturally I thought about renting out our current home.

Will the bank want to see this house rented out for x amount of months before they approve me for a new loan so I can move?

Will they require me to have a certain amount of money set aside in the bank as a backup for this house?

Is there any other information you guys have that I might not know before moving forward with this?
