What is the best route when renewing a lease???

[Samuel J Claeson]

Hello,

My current tenant has agreed to stay an additional 14-months (great tenant!) and I'm curious what the best route is to renew a lease?  My first thought is that it would be the easiest to amend the lease end-date...?  If that's the case, does any one have an amendment template that they'd like to share? If not, I'd love to hear what others do.  

FYI The current lease ends March 31, 2019 and it is the MINNESOTA STANDARD RESIDENTIAL LEASE.

Thanks in advance!

Sam
