You got me thinking, gas is getting expensive :).   

If you don't have furnace gas lines already ran, then you can install a heat pump which does both heating and cooling.

I'm about to go under contract to purchase a SFH with an extra lot that happens to have an old oil/gas tank underground.I've done some preliminary searching and all I could find in terms of cost to remedy is anywhere from $2,500 for a basic removal, all the way up to $100k for a major contamination problem (replacing all the contaminated soil).The sellers are selling the property as-is, but this is an item that has a massive range of risk so I'm wondering how to better mitigate and reduce that risk.Thank you!

Figure out utilities (water, trash, electric/gas, wifi, lawn service)5.

Maybe unorthodox but possibly see if you can advertise at the local gas stations for cleaners, handyman, and maybe even a manager who can watch the place for you and accept your packages.

As Zorya said you will have other bills (phone, gas, electric, etc) that you are paying and those will help with your credit score.

Owner pays water/sewer/trash/gas. 1900 sqft- 6 Bed/2 bath (4/1, 2/1) for 285k off market, no garage.

Talked to an original owner neighbor, they mentioned they had the same and it would come on by itself somehow but they didn't know what triggered it.Before digging through our attic - I figured I'd ask here...Could this be part of the overall heating system (gas furnace / forced air)?

I’m considering a capital improvement on my five unit building which would primarily yield on the expense side Specifically I am considering converting my oil steam boiler and hot water heater for the entire house to individually metered Hi efficiency gas and on-demand water heater’sThis would mean that each unit would be responsible for its own heat and I would save on oil as Well as potentially the water bill with individual meters for each unitWhat do you consider an acceptable return on investment for such an improvement?

There is high traffic in this location and there is Walmart close by and 2 gas stations in close proximity of the lot.
