I have had an interest in real estate from a young age.

I would love to be able to retire at age 50 or 55 and I think investing in real estate could be the way to get there. 

Their lease ends on 8/31, and they have the option to resign or become TAW.The problem comes in because I am moving since life (career changes and aging parent).

Last month, his daughter, son-in-law, and their five kids aged approx. 12-1 yr old moved in from out of state temporarily while they look for a more permanent place.The lease prohibits guests for more than 30 days without my permission.

I am very young, 19, and have a very well paying job for my state and age.

These are two commonly culprits, especially depending on the pipe material and age of the sewer.

I like medical buildings given the ageing population with Fortune 500 tenants.

@Eamonn McElroyFor ages individuals and businesses have bartered to get services and goods they want or need.

The age of the property would put it in a safe harbor, however of note you would need an "intrusive" or sometimes called "forensic" addendum to the needs assessment (PCNA) that reviews major building components like the breakers and sewer lines for adequacy. 

Maintenance and capex 8% is pretty close depending on age and condition.
