They are a real estate law firm, who, it appears, has preferred relationships with brokers that they work with and farm the business out to.

I have used state farm and have no real complaints, but I wouldn't mind working with a smaller local company.  

I actually have three separate lists - one for residential properties, one for commercial, and one for vacant land, farms, and ranches.

I am a fan of the Hope Valley (not Hope Valley Farms) area due to location and the lovely homes in the core part.  

I am told we can easily put a truck stop, a feed store, a Tractor Supply type place would be easily allowable, Even a legal marijuana farm is allowed.

Like others, I highly recommend it.If your focus is Chester county only, I would add Downingtown to your "farm" area, you may have some luck finding small multi-family (2-4 units) to house hack.

You should know every property that comes up for sale in your "farm".

I also have six local long term rentals in my hometown and a 9 ac. farm in Costa Rica I'm developing (that's a whole other story).I don't aspire to own tons of properties, I feel what I currently have is enough to tide me over.  

Once I got my head around this I now have to problem farming out nearly everything I can while I focus on what I do best [acquisitions/sales and Call of Duty...].

Most real estate investors are better off with an independent agent rather than a direct writer like State Farm, Farmers, Allstate, etc.
