When you're buying a home with a propane tank, confirm first whether the tank is owned or leased. An owned tank conveys with the house and lets you shop suppliers; a leased tank stays the propane company's property, locks you into their pricing, and needs a transfer or buyout. In Montgomery County — mostly Potomac and outer areas without natural gas — verify ownership in writing, check underground tanks against county permit and setback rules, and make it an inspection-period item so you can negotiate before closing.

When you're buying a home with a propane tank, confirm first whether the tank is owned or leased.

Most homes in Bethesda and Chevy Chase run on natural gas or electric, so the propane tank in the side yard catches a lot of buyers off guard — especially in Potomac, North Potomac, and the outer pockets of Montgomery County where the gas mains never reached. If you're under contract on one of these homes, that tank is not a dealbreaker. But it is a due-diligence item you want to handle deliberately, because a few questions answered now can save you real money and a real headache after closing.
Buying a home with a propane tank raises a predictable set of questions — who owns it, what fuel will cost, whether an underground tank is sound and permitted — and every one of them is answerable well inside your inspection period. Here's how I walk buyers through it.
The first question when you're buying a home with a propane tank: who owns it?
Before anything else, find out whether the tank is owned by the seller or leased from a propane supplier. This single fact drives almost everything else about the deal.
An owned tank is treated as a fixture — it conveys with the house, and once it's yours, you can shop suppliers and buy propane from whoever offers the best price. A leased tank is different: it stays the property of the propane company, even though it's sitting on land you're about to own. That means you either continue service under the existing lease, sign a new agreement with that same supplier, or arrange a buyout.
Under Maryland law, fixtures generally transfer with the property, but a supplier-owned tank is a specific exception — it doesn't come with the house just because it's bolted to a pad in the yard. So don't assume. Ask the seller for proof of ownership: a bill of sale, the original installation invoice, or a purchase receipt. If the seller can't produce paperwork, call the supplier whose name is on the tank and confirm the status directly. I've seen buyers move in convinced they owned a tank, only to get a lease invoice weeks later.
Leased vs. owned: why it changes your costs
The reason ownership matters so much comes down to pricing and freedom.
When a propane company owns the tank, the lease almost always requires you to buy fuel exclusively from them — and companies typically charge a premium per gallon when they own the tank versus when you do. You lose the ability to shop around, which in a volatile fuel market can mean paying well above the going rate every winter. Other suppliers won't refill a competitor's tank, so you're effectively locked in.
If the tank is leased, here are your realistic paths when you take over the home:
- Assume the lease. Continue with the existing supplier under a transferred or new agreement. Watch for a transfer fee, and read the term length and price terms before you sign.
- Buy the tank out. Ask the supplier for a buyout price so you own it outright and can shop fuel. This often pays for itself within a couple of years through lower per-gallon rates.
- Switch suppliers entirely. This usually means the leasing company removes its tank and a new company sets theirs — and you may owe an early-termination or tank-removal fee.
One small but real detail: whatever propane is left in a leased tank at settlement generally becomes yours as the new owner, so a nearly full tank in January has value worth noting in your negotiations.
Underground vs. above-ground tanks in Montgomery County
Propane tanks come in two forms, and the difference affects both your inspection and your paperwork.
Above-ground tanks are the visible ones you'll spot in the yard. They're easy to inspect, easy to prove ownership on, and simple to replace. Underground (buried) tanks are tidier to look at but harder to evaluate, because you can't see the tank body or its condition. Buried steel tanks can corrode over time and need proper corrosion protection, and a leak is a safety issue rather than the soil-contamination problem you'd worry about with a buried heating oil tank. Propane is a gas that dissipates, so the environmental profile is different — but you still want documentation on the tank's age, material, and last inspection.
In Montgomery County, propane tanks are regulated through the Department of Permitting Services, and underground tanks carry setback requirements — Maryland generally requires a 10-foot setback for an underground tank regardless of size. If the tank was installed without the right permits or sits too close to the house or property line, that's something you want to surface before closing, not after. For an underground tank, ask whether there's a permit on file and when it was last leak-tested.
How to handle the propane tank during your inspection period
Your inspection window is exactly the right time to deal with all of this, because it's when you still have leverage. A standard home inspector will note the tank and check the connected appliances, but a general inspection is not a full evaluation of the tank, the buried lines, or the regulator. Treat the tank as its own line item.
Here's the checklist I give buyers:
- Get ownership in writing. Confirm owned vs. leased and collect the bill of sale or the current lease agreement.
- Read the lease terms. If leased, note the supplier, pricing, term, transfer fee, and buyout price.
- Ask for the tank's history. Age, above- or below-ground, last inspection or leak test, and — for underground tanks — the county permit.
- Confirm the disclosure. Maryland's residential property disclosure (RP §10-702) is where a seller should note a leased tank or a known issue; a latent defect must be disclosed even on an "as-is" sale.
- Fold it into your strategy. If something's off, you can ask the seller to buy out the lease before closing, credit you for a buyout, or address a tank that's past its useful life.
Because this all lives inside your inspection contingency, it gives you room to negotiate after the inspection rather than absorbing a surprise later. Buyers looking at homes on a well and septic system in Potomac often find a propane tank in the same yard — these rural-edge properties tend to come with a cluster of private systems, and it's worth evaluating them together.
The bottom line
A propane tank shouldn't scare you off a house you love. Plenty of excellent homes in Potomac and the outer edges of Montgomery County run beautifully on propane, and buying a home with a propane tank comes down to knowing what you're actually buying: who owns the tank, what you'll pay for fuel, and whether an underground tank is properly permitted and sound. The buyers who get burned are the ones who assume the tank conveys and never read the lease; the buyers who come out ahead treat it like any other system in the house — inspected, documented, and negotiated. Answer those questions during your inspection period, and you turn a yard-side surprise into a routine part of the deal.
