Don't approach, definitely stay as far as possible from cubs, don't leave food out. 

However, I'd rather cater to families than large groups of adults that might have bad intentions...

Problem is the second I do that I can kiss decent school districts and modern amenities (restaurants, movie theaters, stores other than the dollar variety) goodbye, plus some of these places would even be considered food deserts.

It ranks areas based on the following data points, obtained from the American Community Survey- Median Home Value- Median Rent- Median Household Income- Poverty Rate- SNAPS (Food Stamps) Rate- College Graduation Rate- Vacancy Rate Hope this helps! 

We always had food on the table, but the topic of money was a big 'no-no', later come to find out that we were just like so many other families out there just trying to 'Keep Up With The Joneses'.As for your sister, she's young, and I would think could be more of a visual learner.

The hotels I focus on buying are those that cater to the business traveler and those attending business conventions.

We have a small/mid sized group of local investors meet up every week anyone is invited to come for free, free food as well. https://www.biggerpockets.com/forums/521/topics/739100-am-mastermind-every-thursday-morning

It is called moving up in the food chain.

Pick good locations that cater to the better schools (and decent freeway access) if you are doing single family.  

Consider this food for thought..
