@Ashley Swansend If you go the route of putting mobiles on land, you'll need to check with the local zoning department regarding restrictions (if any).

@Doug Pretorius City Hall has a department called Assessment Rolls, and you can sit in front of a computer terminal there for hours, taking down property owners' names to your heart's content.

I would expect that most benefits would be with the building department. 

If not than most states have on the State's State Department Website (or something similarly titled) a list of banking institutions who are legally registered as banks in the state you're in.

Rather than calling the departments of real estate and asking if something is legal (they're not going to advise you on the legality of what you are calling wholesaling) READ the regulations on who needs to be licensed in that state.

There are a lot of questions that need to be asked with the zoning department.

I found someone at the DMV investigations department that was very helpful.

Now as @Dave Foster will concur, Pennsylvania is the only state out of the 50 that will not allow the capital gains due to the state to be deferred; that means when you sell a Pennsylvania property, even as part of a 1031 exchange, there will be capital gains tax due to the PA Department of Revenue.So that is a drawback if you get a property in PA as part of a 1031.

I would start with calling the HoCo Department of Housing and asking them directly: 410-313-6320Or call the HoCo Department of Licensing, Inspections, and Permits: 410-313-1830In my search, I did find this useful link that does give some HoCo-specific rental information, although not the answer to your question:https://www.howardcountymd.gov/LinkClick.aspx?

We spoke with city water department and he said don't worry about it.
