You are defintley on the right track in terms of your thought process.Just a point of clarification/semantics:Short Term Rental - Usually a nightly furnished rental with perhaps a 2-night or 7-night minimum stay. 

Are you looking to stay focused on your businesses and spend minimal time on the real estate?

.- Only allow MAX 3 days for them to make payment or you send to attorney3) Do a polite, but firm call the day before court to see if they plan to pay to stay.4) Once you receive eviction judgment, do another polite, but firm call to see if they plan to pay to stay or are moving.5) Payment Plans: desperate people do desperate things - require the TENANT to put in writing specific days & amounts.

Sometimes it’s about finding the option that fits best for the homeowner’s circumstances.So here’s what I’m curious about:Have you seen examples where a foreclosure situation ended with the homeowner staying put?

Where STRs differ (and why people talk about them more)Short-term rentals sometimes qualify as an “active business” (if the average stay is under 7 days or you materially participate).

looking to house hack a duplex is it ok to have negative cash flow while staying there and if so how much negative cash flow is too much 

Some states have limits on how much you can collect, so it is worth double-checking California law or consulting a local attorney to stay compliant.It sounds like you have done a great job keeping tenants long-term.

Trying to keep expectations realistic and stay consistent.... even on the slow days.

Pat, I have been managing my properties for a long time and stayed away from management companies for the reason of them not being diligent and prompt with everything from leasing to maintenance, etc.

The larger and/or more unique the stay the better you will do.
