How long do you have to live in Primary residence before renting?

[Jeffrey Suarez]

 I want to rent my home in about 2-3 months, move 30 miles closer to family. 

I will be keeping part of the home for my personal belongings. garage and RV storage. ( I started another thread about building adu so I could be there part time in the future)

I currently have a primary residence loan funded by fannie mae. 

I refi in Nov 2020. I have lived in the home 4 years.  I am in the middle of a home equity loan, but need to know if there are any reprocussions. I don't want to be accused of mortgage fraud. 

Should I stop the home equity loan, or at least let them know the situation? Lender is US Bank so I am dealing with a lot of robots there that don't really have answers. .
