Good Afternoon, thanks for your question. You may have already found your answer, however, I am happy to help if you haven't. Does your property have a gas water heater or electric? Do you have a condo or a single family home?
From past experience, the price can range from $250 to $3,000. I'd be happy to get you taken care of, you may reach me directly at 713-397-1999 or email me at Sibel@kw.com. I have affiliated partners that can also reach out to you.
First look if you have a gas meter, and if you do, look behind the electric stove many times it has a gas valve and all you have to do is to buy the stove.
A lot of this cost will depend on the current location of the gas meter relative to the location of the range in the kitchen. I had a client who wanted to convert the electric range to gas in a property she was purchasing and my contractor quoted her around $350-400. But, again, the location is going to be a key factor.
I'd be happy to send my contractor's contact info if you'd like it.
