any suggestion gas to what nitch would produce the best results?

I would like to convert to Gas to save money on utilities and to look better to long term tenants.  

Unless he lives very close to it, he'll probably consider it "too much work and too much gas" to travel there just to throw a rock through a window.

Average it out over 12 months and increase the rent plus 10% as "utilities included".It is preferred to spend the money to split the utilities and add second meters (hydro, water, gas) to be able to put utilities in the tenants names.

4) Does anyone here have an issue with landlord-paid heat that uses natural gas to boil water?

Added refrigerator and new stove (converted from gas to electric stove).

Any strategies, don't have much gas to drive for dollars much less drive to those counties.

The county condemned it because he change the gas to electric and never pull permits to do so. 

Prices are a moving target and here in Calif, the change quickly due to the prices of gas to transport wholesale to retail. 

If you have gas to the water heater and the furnace, I have to imagine 150A is fine for most SFR, but again, the electrician can do the load calculations.As for price, I don't know the prices in Phili, but I can't imagine $1900 is too expensive.
