I suppose that maybe an app would show what day/time the record was created...

Its best to ask her when is the best day/time, and then mail her a notice or post it on her door that you will be entering and taking pictures for prospective tenants.Like @Max Tanenbaum said screen screen screen.  

I've walked around Four by Four looking at houses and never felt unsafe (during daytime, of course). 

Think about how each property will photograph and how best to present its desirable features.If it photographs extremely well (Hire a professional with great lighting, and have it photographed at day time and at night time), has desirable features and you promote it those 3 ways, you should have a strong occupancy rate through the year. 

If the possessions is given up earlier, then the 21 day time clock starts when the landlord gets possession. 

I allow vaping but not smoking. 

This way I can update people on what day time and what to bring thank you.

Here is the bottom line, noise during the day time is allowed.

She has also vaped in the house in front of me when the lease clearly states no smoking or vaping of any product.

When one tenant wants to leave, I want a very clear day/time of their departure.
