60 Day notice and extension to this rule

[Mike Flora]

I gave a 60 day notice, which is up Nov 15th, and tenant wants to stay and pay for all of November and possibly longer. Property is vacant and he does not live there and using it for storage. This is going to be a fix and flip property and I have a year note with principal only payments which tenant rent covers for me every month. So I don’t mind him staying and paying for now, but I need to know what can be written up to extend this situation where I would not have to write up another 60 day notice and continue after the 15th of Nov and still have the opportunity to start an eviction immediately if need be. Is this as easy as writing something up ourselves and both signing off on it. Don’t want to waste too much time on an eviction if need be but him paying my principal only payments of $1,000 a month also helps.
