Controversial Real Estate Topics

[Dillon Alder]

Hi! I am a landlord and am taking my final writing class in college and want to do a research paper on something real estate related (Might as well research what I am interested in). I need your help finding something that is argumentative and can be researched fairly easily. Any ideas would be appreciated. 

Some ideas I have:

Landlord/tenant laws by state- but not sure what I would argue. 

Zoning laws/issues.

Eviction process and related laws per state. 

With these ideas I don't know what kind of thesis I would make or what kind of argument I can bring. English is my weak subject.

Thanks in advance.
