Acquiring Existing Tenants upon purchase

[Michael Sontheimer]

Hi. I purchased a duplex that has each unit rented. I would like to make some improvements to both sides and up the value of the property. The renovations would probably take a month and I need the property to be vacant to make those improvements. 

Is there any way that I can legally end the current leases early? Or maybe someone has experience with possible 'rewarding' the tenants to leave early?

Otherwise I will continue with the same tenant(s) for almost another year until their lease simply expires and not renew it.

Thanks for your comments!
