@Kimberly T. just further emphasizes get a engineer and price to fix.

It is a cool property for kids with all kinds of places to play hide'n'seek, nice back yard and all.When talking to your guest, acknowledge that clicking the button to indicate the property was not suitable for kids was clearly not enough of a note and that you will emphasize the issue for future guests.

I alway make the point of emphasizing that our properties (not just the buildings) are non-smoking and that our policy is a $100 fine on first offence and, on a subsequent offence, they will be required to move.Depending on the legislation, its quit probable you cannot prevent your tenant from smoking on the street or pavement in front of your property.In the future, you are well within your right to deny a future applicant because they smoke  - just make your non-smoking policy very clear up-front.

Emphasize that you want to invest for the children's future.

You've been given a lot of great advice on this thread.One thing I'd emphasize to you is a key reason REI is such a great tool is leverage: you put as little into a house as possible, especially with the current low interest rates, in order to get leveraged returns.

I’m torn...I want to keep my cleaners happy, but I don’t want to set a precedent...especially since this is such a subjective thing.Again, I want to emphasize that she has been awesome so far as a cleaner...always on time, I constantly get reviews on how clean the place is, etc.

I think this was also emphasized in the book, and clearly spelled out the factors that may be most important. 

Change your story each month as different stories will resonate with different people AND use each story to emphasize one of your “who do you know…” questions.
