There will be a big push to eliminate gas connections in the coming years.

For example, when the power goes out during a storm and a tenant buys a generator, do you pay for the generator and the gas?

Quote from @Matt Lewis: I'm purchased my first commercial property this year and just had a water leak from a pipe going into the water heater in one of my tenant's space.

This was the most high risk investment I've ever seen, and keep in mind I've done oil, gas & mineral exploration investments so that's really saying something. 

By installing our own, we remove the wear and tear and damage the tenants do by moving W/Ds in and out and hooking them up wrong (which is common) and using cheap components that cause leaks and destroy floors and walls.

We drive two Tesla EVs, so if we count in the $ delta we saved from gas $ to charging at home, our projected ROI on the total system (~$40k post rebate) is about 8 years.

Fortunately I was able to add a 30” model...so I got to spend $400 on a nice whirlpool stainless gas range that looks decent too!

If you want to make it easier, look for one where it's all direct replacement meaning the water and gas and appliances are staying in the same place - less permits and less cost.

Hot water heater, furnace, gas, electrical box, HVAC, oil tank, plumbing pipes.

After the tenant moved in the repair calls starting coming in 9 times in 12 months - backdoor was stuck again (that was part of minor repairs), heat went out, AC not cooling, kitchen sink leaking,  etc.
