My parents struggled really hard (and still do) financially so my sister and I are trying to really break out of that mold as adults. 

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

I have tried asking guests to invite every adult staying into the Airbnb booking. 

Seminole for Example has a lot of great traffic and tons of spots to eat, drink, socialize for adults and kids.I know Cape Coral is picking up in terms of STR's with the complettion of the 7 Mile Island and more construction lately. 

If something horrible happens (like your handy man who you have given the keys to all the properties rapes your female tenant (you didn't know he just got out of prison for rape) (no insurance coverage for you by the way because intentional torts are uninsurable) you will lose everything you own.

adults=1&am...Thanks in advance,Aaron

Disregard the male female split.  

Look I was a "troubled youth" and I unfortunately tacked on 5 ADULT f5 felonies and nearly 5 years of lock up time by the age of 17!

We have had people try to move into a one bedroom with two adults and a baby.  

This is because, as adults, we ALL have *some* familiarity with cars and money and we know how the business world works!
