@Tyler HenryIt could be a special exception or like you said grandfathered depending on when ordinances were put in place or changed. 

My goal is to gain enough financial freedom to supplement what I currently make so I could leave my desk job and work on my own hours so I can be home with my family.I currently have an opportunity to invest with an investor who is to my understanding very successful in multifamily, but it seems to come at a hedty cost $10-15k.

I get about 4 notices a year for special sales, but I only buy about 8 to 12 a year. 

Hey BiggerPockets,I'm interested in starting my real estate investing with small apartment buildings (around 5-12 units) in the Pittsburgh area but am having a tough time finding real estate agents who excel with these property types.Any suggestions on generating leads and finding agents who specialize in this apartment building size?

Getting a special and start off with low down payment is not as good as you think but if the  the location is important as a consideration, the demand for what you buy property and tenant screening, it's in  growth area, is it located within a diverse area, the parking that is available, do you have deep enough pocket if funds are needed, Do nearby amenities exist, is there any nearby retail stores and what are they and does it fit your ideal tenant, and are there any existing tenants. 

So Dan, I got on the phone and found a local attorney that specializes in real estate law.

You will provide one to the tenant and keep the other one.The reason why it is important to revise the lead certificates during your inspection contingency is due to the fact that number 1, kids specially babies can get sick and number 2. if the seller did not  do a lead inspection then he might not be doing the City's rental inspections either. 

Diversify when you don't have knowledge...specialize when you do.

Most people tend to specialize.

@Alex Howard we specializing in structuring purchase money mortgages...and I do a few of these a year...my personal play is a little different.
