@Nathan Simons I wouldn’t kick them out so quick, but that’s just me. In Florida, 5 day grace period is standard. Not sure about your area. Once you learn the local law, make sure to post a 3-day notice to pay or quit as soon as you can, even if you suspect they are going to pay you by the 8th. If you don’t post the 3-day and wait till the 8th, if they fail to pay, you can’t just start the eviction right then. The 3-day has to come first, then the waiting period. It starts the clock in your favor. This is why it’s so important to do that part as soon as possible.
As far as the eviction goes, I would post the 3-day ASAP and then wait until the 8th to collect. If they are playing games, start the eviction on the 9th. If you give them a chance to pay on their promise date and they were being truthful, you will have avoided a lot of time and cost associated with filing the eviction and then cleaning/fixing up the unit, marketing, and not to mention vacancy. If they do pay this month, be sure to remind them firmly that if they are late the next month you will not give them a second chance, and you will start the eviction process as early as possible. Just me.
