Househack - everyday details and rules for housemates?

[Charles Moore]

Hi, all.

I'm in a position where I will soon be living alone in my 4BD, 3BA 2500 sq. ft house in Seattle's north end -Lake Forest Park - which is one of the more sought after and expensive areas around Seattle. I've decided to pursue a househack strategy with this to cover the mortgage and other expenses I have. I'll offer the three upstairs  bedrooms - including the master with private bathroom and walk-in closet - to three different tenants/housemates, while I take the least desirable downstairs bedroom. I'm an experienced landlord holding other properties and will be applying the same principles to this, but I haven't had housemates before. So my questions are about day-to-day living. What are the best practices for the following:

1) Are groceries and meals individual or collective?

2) Are dishes individual or collective?

3) vacuuming common and private areas?

3) consumables like toilet paper?

I already know I'll charge the tenants a fixed monthly amount for all utilities, internet, and cable.
