While becoming an agent can help you logistically, it is not absolutely necessary as an investor. 

If you want good ratings/reviews, be prepared for being available at all times via text/ phone calls about bus lines, transportation logistics, where the best brunch places are etc.

Keep your requirements firm and clear and if those requirements can't be met, make considerations carefully and add fees/deposits/last months rent etc. as necessary.What concerns me more than the demographic is the financial aspect and logistical aspect. 5 tenants 'jointly and severally' comes with a lot of extra baggage; friends, cars, parties etc.

The logistics of such a feat much be phenomenal.

I will be doing all logistics, so we plan on splitting the profits on sale.  

Some of the questions relate to legal compliance, but others are more logistical (who do know that might invest with you)?

Yes my lease does allow me to enter and to show the house, but logistically they have a dog and a busy work schedule, so showing it will take some doing.

What we find with young kids is as soon as they become young mothers they would prefer to stay at home & raise their children rather than the drudgery (& logistical nightmare) of working to pay the ever increasing expense of daycare & after-school care until one of the parents rushes home.

As a logistical matter, keep in mind that property records are not always updated.  

I would think that largely, the same logistics still apply for both.
