How to Sell Your House with Foundation Problems

Selling a house with foundation problems can affect home value, buyer interest, and financing eligibility, but you still have options. Whether you repair the damage or sell as-is, understanding disclosure laws, pricing strategies, and marketing approaches will help you make the best decision.

Understand the Scope of the Damage

Foundation concerns range from minor home foundation cracks to severe structural instability, so assessing the extent of the damage is crucial before listing. Common signs include:

• Wall, floor, or ceiling cracks, particularly stair-step or horizontal patterns
• Doors and windows that jam or fail to close smoothly
• Floors that appear uneven or sloped
• Gaps forming between walls and ceilings
• Noticeable foundation sinking or settling
• Moisture buildup or water damage in basements or crawl spaces

A professional home foundation inspection, which includes damage assessment and repair recommendations, generally costs between $300 and $1,000, depending on home size and location. The larger the foundation, typically the higher the cost for inspection.¹

Know Your Legal Obligations (Disclosure Laws)

In the U.S., sellers must legally disclose foundation problems to prospective buyers. Failure to do so can lead to lawsuits, contract cancellations, or other legal consequences. Each state has specific disclosure laws. Here’s an example of how laws vary:

• California: Requires a Transfer Disclosure Statement listing known structural defects.
• Colorado: Sellers complete a Property Disclosure form, covering structural, plumbing, and electrical concerns.
• New York: Sellers provide a Property Condition Disclosure Statement or pay a $500 credit to the buyer—an option for those who prefer not to disclose defects.

Concealing structural damage can result in fraud claims, sale reversal, or financial penalties. Sellers should review state-specific real estate regulations, especially in states with stricter mandates. 

Consider Repair Options

If the damage is minor, house foundation repair can be a cost-effective way to increase home value and attract buyers. Common repair methods include:

• Slab jacking (leveling sunken concrete slabs by injecting grout or foam beneath them)
• Piering (installing steel piers to stabilize and lift a sinking foundation)
• Sealants (fixing small cracks to prevent water intrusion and further deterioration)

The cost of fixing a house foundation varies based on severity, usually ranging from $2,200 to $8,100, with major repairs costing upwards of $30,000.²

Ask Yourself If Selling As-Is Is Right for You

Selling a house with foundation issues as-is can be practical, especially for a quick sale, but expect lower offers as buyers factor in home foundation repair costs. Investors and distressed property buyers are likely to purchase homes with structural faults.

Structural concerns can reduce a home's value, with the exact impact depending on the severity of the damage, local market conditions, and buyer demand. Severe issues often restrict financing, as lenders require inspections or costly repairs, reducing buyer interest. This makes cash buyers the most dependable option for a quick sale.

Be Strategic With Pricing and Marketing

To attract buyers, price your home competitively and consider:

• Getting a professional appraisal to determine fair market value
• Highlighting strong selling points, such as location or recent upgrades
• Targeting investors or buyers seeking fixer-uppers

Companies specializing in buying homes as-is typically offer cash deals, helping sellers avoid lengthy negotiations and financing delays.
