Think of all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

When I think of some of my most cherished memories as a kid, they involved pizza picnics on the lawn (my mom makes amazing pizza), going berry picking in the bush with my parents or grandparents and time at the lake.

It's pretty much completely hands off where they do all the renting, calls, money collection, maintenance, lawn/snow care, etc... 

That tends to keep up with increased costs of taxes, insurance and lawn maintenance.  

But if I hire a lawn guy to landscape around the office, I could call him an IC... as long as I don't instruct him on how tall to prune the hedges...

Now, figure vacancy, repairs, utilities, lawn care, snow care) is there anything left over?

But the carpet was not steam cleaned ...full of stains and bubble gums everywhere... the lawn was now even maintained...full of weeds...grass almost dead... so we had to put some fine for carpet and lawn...And also for the lease breakage...

Although tenants will take care of the routine lawn mowing, they will not care for the landscaping adequately.

If you are not a licensed entity without a managing broker you cannot: write ads of properties (owners must write ads), you cannot negotiate leases terms with the applicant, you cannot collect rent in office (regardless of whether it is made out to landlord), you cannot operate a trust account, and finally you cannot enter into contracts for services (i.e. hire a plumber, lawn service, trash company) on behalf of the landlord. 

Don't forget to figure in annual expense for trash pick up or lawn care.
