You, as the new owner, have to provide those same sleeping arrangements.  

What other options might we have to complete this type of project, and accomplish this type of arrangement?

We've arranged for funds to pay for the property.

From my experience so far, this can be a very painless (and profitable) arrangement if you put the work in up front.

If you're comfortable with everything and just need help to negotiate a fair arrangement, then hey, it is your money and your decision.

I've arranged a tree magician to make it disappear next month.

Legal Zoom and Rocket Lawyer can put together a bare-bones agreement, but they usually don't hold up well in court if there are numerous partners or special arrangements, which is what it sounds like you have.

I agree...not sure about your state, but, if you don't have a payment, partial payment, and/or specific payment arrangements with explanation of when and where the money is coming from by your due date or grace period, let alone 2 weeks into the month, you have to start the process....In CA we give them the 3-day notice to pay or quit, that has to be non-responded to before we can actually file for the eviction, that cost another $500+ depending on if they dispute it.Of course, you should try and talk to them and gauge their intentions and let them know yours before any action.

When they contact you ( and even the tenant that’s gone dark will call) to make arrangements to pay you can negotiate whatever deal you want wave or keep late fee, (if they can’t pay rent a late fee is useless.

Most room renters are that just to get cheaper living arrangements.
