Hi Roee, right now the fastest growing neighborhoods of Pittsburgh are Ambridge, Bellevue, the Hilltop neighborhoods (including Allentown and Mount Oliver), North Point Breeze and Etna. 

@Michael WagnerAlso, have you ever thought about motor home parks?

Resources out there in the motor city would be great!

Places like Kitrell, Wilson, Rocky Mount, Roxboro, Sanford, Oxford, and towns with a similar radius are all interesting places to consider. 

I would deal with it as abandoned property, sell everything off, recover as much as you can, then move on.Contact the Department of Motor Vehicles.

You also want them to explain which parts are working fine so that you know they checked all the sensors, blower capacitor, blower motor, exhaust motor, and burner. 

You probably don't even have ceiling fixtures but if there are a new box and conduit can be mounted right on top and down the wall to a switch. 

If you don't want to go to the expense of a security system, they have fake cameras with flashing lights that you can mount around entrances.

Heard a lot about Huntersville, Mathews, Mount Holly etc but have no ground level understanding So far I am relying on Zillow, Redfin only to find properties so also wanted to check what are other reliable local / online MLS sources to look for prospective properties.

i have a basement where i used cassette mini split which throws air in all 4 directions as its a long 20ftX40ft space. in the other adjacent room i placed a wall mounted split. both of them have one condenser unit outside with a heat pump. its easy to maintain but its double the cost of the typical HVAC unit. for me a typical 1.5 ton unit costs around 6k unit and duct and labor. but with the ceiling mounted 4 way and wall mounted one way Mitsubishi costed me around 12k.
