Getting your rental back from tenants. Question.

[Jay Mayer]

Hello, 

I am a newbie landlord by chance. Please bear with me. 

Tenants have lived in what used to be my primary residence for the past few years. They have been good and can't complain. 

I am about to renew the lease, but due to uncertainties that came up in my life, I "may" need to move back to my home. This may happen in the middle of their lease, if they sign another year. 

I know I can make the lease shorter than a year, but I am not sure when I may need the home back. 

Is there any way to add something to the lease that I can use in order to get the home back for "any" reason as a Landlord? 

Or how can I work this out now that I need to draw up the new lease again in order to help me get the house back when I need it?

Any advise is super appreciated!

Thanks
