As I attempt to buy my first duplex/triplex/quadplex, and seeing as I currently have no frame of reference, I'm having a difficult time knowing if my expense estimates are accurate. 

Unnamed businesses vaguely referred to that make lots of money don't say legal income to me.   

Pet fees (whether one time or monthly rent) are not legal in every state, so I suggest you refer to your state laws as well.

For reference my process typically goes as follows: 1) Lead comes to me from aparments.com 2) I send out a template I have been refining, outlining the specifics of the rooming house and some FAQs I get a lot.

Here is what I learned for future reference and in case is useful to others:1) When buying a property that has Section 8 Tenants, new owner will process the change of ownership one the sale is complete.

@David Lewis I don't really know if I have enough knowledge or not but I'm gonna keep trying to make things happen and reference my books for any problems that arise.

I take notes while reading and listening to reference back to. 

I only refer my handyman to people I know, not random people.
