I know federally backed loans are required to give 30 days notice but I believe that because it is a triplex and the other two units aren't owner occupied it allows me to do a 3 day notice. 

What I am trying to better understand is at what pointy that restaurant owner able to either delegate or reposition so he / she doesn’t have to the restaurant every day. do they need to obtain more restaurants or keep offering more to their current customers?

They have been incredibly transparent but they are currently deciding on a capital call or selling the property at a major loss (70-80%).

I don't know if that is included in the total rent numbers the owner supplied. 

Or are you actually talking to a bank about buying the note so you can see the notes and credit on the owner of the property?

Pricing - If you cannot check your competitions price and adjust yours daily you may want pricing software (PriceLabs probably best for single listing owners/operators). 

I do single family "off market" that I take over with owner financing, subject to, wraps and lease options.

It is similar to you renting a hotel room and deciding to stay.  

For example I know many who are now just lending because they are getting 10-12% short term which is far better than any cap rate on real estate. you do not have the equity upside as you do real estate but its a way to play the short game to see what happens over the next 12-24 months and decide when you want to buy.

No syndication experience but there are about a dozen quality RV/Mobile home parks on market in Oregon, several with owner carry options that can be passiv-ish with management in place.
