I do Zillow rental manager (which posts to a handful of sites) and FB marketplace.  

We can meet at any of my sites or yours.

This can be done by using sites like AirDNA, or by clicking on Airbnb/VRBO and seeing what similar properties are renting for and how booked they are at what rates. 

@Matt Rodak runs the site and I have met him a few times and had a number of discussions with him (more from the investor side not from the flipper side).

Its a gamble to go the permit route or not in Philly and absolutely matters the neighborhood/your neighbors as they are usually the folks that will call L&I on you OR if your property is near other construction sites where inspectors would be traveling to/from.

Quote from @Tyson Thompson: Your best option is to use a data site like AirDNA. 

Provide four to five copies of drawings size 24"x 36" and 11 each Site Plan/ Boundary Survey.

Hey everyone,Are there any sites you would recommend for market research on an area other than looking at census data?

Locally, I know an investor that runs a crazy profitable trailer park where he is probably pulling in a 20%+ annual return on his investment - but he has to self-manage because no one will touch it, collects rent and deals with evictions armed, and has several "overseers" living for free on site to make sure no one burns the park down.
