TIA The petroleum products leaking in the ground may be the best way to get results.

Orange is communications (red=elec, blue=water, yellow=gas, green=sewer, forgot what white is).  

I don't know if this makes it easier or more complicated, but our upper level may not have any gas services at all (husband is going to the property tomorrow to see if upper water heater is gas or electric, and whether washer/dryer in each unit are gas or electric).

Your guests are not going to notice or care about the leak under the sink or that the hedges need to be trimmed.

Loosing deal for the bank, water, sewer, gas, electrical, lawn care, and trash added up to more that they collected. 

Besides a central gas heated inside almost new home.

Recently, they engaged a plumber to investigate a gas leak and the recommendation was that the gas line needs changed in one the units at a cost of $3600.

@Kev PitoIf you purchase a gas station, get a Phase I Environmental Site Assessment performed.

I own RE (STVR), fix and flips, RE notes, stocks, parts of businesses, land, oil and gas wells  and other things in my SDIRA's.

For instances if there's a leak that were to occur within your unit while vacant, I do not beleive the master policy will cover this.
