Can I still serve my tenant a Notice to quit since I have collected the last month’s rent.

What sites/software does anyone recomentd to collect rent, anyone have like a template of an excell sheet I can use to get organized?

I want to occupy one of the units, my preference would be the 2/1 so I can collect more rent from the 3/2 to go towards my mortgage.
