I just declined an applicant who were a family of 4 adults, parents and 2 children for a 650 sq ft $1700 2 bedroom.

Maybe have an adult, someone you trust work with you. 

While there are things you can do to control local crime in a neighborhood such as extensive camera use, building relationships with neighbors, when you have young adults selling drugs in the neighborhood and carrying guns around you're in trouble.Distance from my base is the next consideration.

You should run credit and background on all adults living in a property. 

We're seeking a mentor in the area that would be willing to help 3 young, successful adults kick off their real estate investing career!

.- Each adult occupant must submit an application.- Your gross monthly income must equal approximately three times or more the monthly rent.- Your debt-to-income ratio should be within FMCC/FNMA guidelines.- A favorable credit history.- Be employed and able to furnish adequate proof of the required income.- Good references, housekeeping, and property maintenance from your previous landlords.- No history of evictions or broken leases.- No criminal background.Is there a clause that I can add to indicate that preference will be given to the most favorable applicant as defined by the above criterion?

Make sure to get an application from every adult that will be staying in the home.

Many cities have implemented a law that states "a maximum of three unrelated adults may occupy a dwelling unit".That means you can't legally rent a huge 5 bedroom, 3 bath house to four students or, say, two gay couples.

What if there are too many kids, not enough adults... or adult gets sick and kids end up on their own for even a minute?

Bill Gulley, I too did not go as a kid, so I have a full appreciation of what life looks like as an adult on both sides of the education coin.
