Rhode Island has more oil-heated homes per capita than almost any state in the country. That means oil tanks — and the financing problems they create — are one of the most common complications in RI home sales.
New England — and Rhode Island in particular — has historically relied on heating oil because natural gas infrastructure expanded later than in other regions. An estimated 40–50% of Rhode Island homes still heat with oil. Many of those homes were built before 1980, when underground storage tanks (USTs) were the standard installation method. Those USTs are now decades old, often made of single-walled steel, and many are corroding or have already leaked.
The problem for sellers is that modern mortgage lenders have become acutely aware of the liability an underground oil tank creates. Heating oil contamination in soil and groundwater can cost $10,000 to over $200,000 to remediate — and in some cases, that exceeds the value of the property. Most lenders refuse to underwrite mortgages on properties with active USTs, which instantly eliminates the largest segment of the buyer pool.
| Factor | Above-Ground (AST) | Underground (UST) |
|---|---|---|
| Location | Above-ground; visible in basement or utility room | Buried underground; may not be visible at all |
| Lender approval | Generally OK if in good condition and properly permitted | Almost always blocks financing — FHA, VA, conventional all refuse |
| Environmental risk | Leak risk limited; easier to detect and contain | Heating oil can leach into soil and groundwater; major liability |
| RI regulation | RIDEM OIL-10; registration if >660 gallons | RIDEM Underground Storage Tank Management Regulations; all USTs require registration + management |
| Buyer options | Financed or cash buyers possible | Cash buyers only (until removed and cleared) |
| Removal cost | $500–$1,500 to decommission | $1,500–$4,000+ without contamination; $10K–$100K+ with leakage |
| Disclosure required | Yes — § 5-20.8 | Yes — § 5-20.8; known leakage is a critical disclosure |
Above-ground tanks in good condition rarely block a sale. Underground tanks almost always do — until removed and cleared by RIDEM.
The Rhode Island Department of Environmental Management (RIDEM) regulates oil storage tanks through two main frameworks:
All USTs in RI must be registered with RIDEM. Tanks must meet tightness testing requirements. Leaking tanks trigger mandatory reporting and remediation. Owners of tanks that have leaked face liability for cleanup costs regardless of whether they caused the leak.
Governs above-ground tanks over 660 gallons and spill response requirements. Smaller residential ASTs may have fewer requirements but are still subject to disclosure law and lender scrutiny.
Sellers must disclose known environmental conditions, including the presence of USTs and any known leakage. A seller who knew of a leak and failed to disclose faces post-closing liability for damages.
Hire a RIDEM-licensed contractor to remove the underground tank. The contractor will perform a Phase II environmental assessment of the soil and groundwater. If there's no contamination, you'll receive a clean report. If there is contamination, you enter RIDEM's remediation process — which can take months to years and cost tens of thousands of dollars. Once the tank is removed and cleared, your buyer pool opens to financed buyers again. Cost without contamination: $3,500–$9,000 all-in for removal + assessment. Timeline: 4–12 weeks minimum, longer if contamination is found.
RIDEM allows a UST to be abandoned in place in specific circumstances (limited access, structural risk, etc.) rather than removed. The tank is filled with concrete or inert material and capped. However, most lenders will still not fund a mortgage on a property with an abandoned-in-place UST without a RIDEM No Further Action letter, so this option rarely opens the property to financed buyers without additional environmental clearance.
A cash buyer purchases the property knowing the tank's status — no removal, no Phase II, no RIDEM letter required before closing. You disclose the tank under § 5-20.8, the buyer accepts it, and you close in 7 days. The offer reflects the tank's presence and estimated remediation risk. For sellers who can't afford $50,000+ in remediation or can't wait months for RIDEM clearance, this is often the fastest and most financially viable path.
No tank removal required. No environmental assessment. No RIDEM clearance needed before closing. Cash offer in 24 hours.

Most require removal and a Phase II environmental assessment or RIDEM NFA letter first. This eliminates financed buyers until the tank is cleared.
$1,500–$4,000 for straightforward removal with no contamination, plus $2,000–$4,000 for Phase II assessment. If contamination is found, remediation costs $10,000–$100,000+. The clean path takes 6–12 weeks minimum.
Yes — if you sell to a cash buyer. No lender means no environmental requirements. We buy RI homes with USTs and ASTs as-is, disclosing the tank status and factoring it into our offer.
Yes. Under § 5-20.8, you must disclose known environmental conditions including the presence of USTs and known leakage. Failure to disclose known leakage creates significant post-closing liability.
