what are the other aspects of real estate

[N/A N/A]

I am new to real estate and got my first home - I am interested to further learning the real estate aspects, but real estate has been known for the following: flipping, rental

I do not want to do either, I am not a handy man and I do not want risk of not being able to pay for a mortgage because of the fact that there are no tenants

What are the other aspects of real estate that does not include the above or what are the alternatives do the above? instead of me being a property manager maybe another can manager the area?? not sure

I went to a seminar and heard there is a paper side to realestate? not sure what that is as of yet...but again what are the other aspects that are rarely mentioned about real estate that does not include the above
