Typically because they felt their tax professional was fine, but not in tune or up to date with the real estate investing portion of their return. 

Same as @John Underwood @Madheshwaran R..Usually it is to check if they are interested in bookings that I couldn't meet due to either no availability or the rare occasion when and AirBNB and VRBO booking for the same dates at the same time.

Include the date, duration, and a brief summary of what was discussed (e.g., "Discussed renovation plans with GC for STR property").

I seriously thought the op date would be 2019, or 2015. 

The windows, roof, electricals, plumbing systems, and gas lines all need major upgrade to bring the property up to date. 

If you rush to get more properties and more cash flow, you generally acquire more headaches so you want to make sure all three of those assets are up-to-date and will appreciate more.

So typically depreciation and expensing of costs usually happen on the placed in service date.

It helps to prevent a tenant from doing what this tenant did and to give you remedies in case the tenant revokes the notice prior to the notified termination date.

When is the latest date we have to provide the notice in order to not have to pay their moving expenses?   

Or pickup dates on Maui.
