Should we buy a house with mold and foundation issues?

This situation comes up frequently. The first question is: does your agreed upon purchase price reflect that this home needs this level of repair (~$30K)? If so, that puts your seller's offer of $5K into a bit more perspective. However, if you asked for $30K and they agreed to $5K, you can potentially counter at a different (higher) number or even counter at your original $30K request - in fact, I would recommend that approach. $5K - $30K is a significant gap. These are not minor issues you are describing. They are material in nature and adversely affect the value of the property. If you have not already done this, I would also try to slow down your process and get some professional opinions on these areas particularly the foundation. You should also be trying to dial in the cost - is it "closer to $30K" or is it $30K or is it more? The real question is whether you are willing to tackle these issues at your agreed upon purchase price minus the $5K. One other thought is this: In Ohio, sellers are typically expected to provide inspection reports from past buyers to subsequent buyers as a part of disclosure. The onus is on the seller, but generally if you have provided a professional inspection report noting these concerns and you terminate your purchase, the seller (and/or agent) should be disclosing that inspection and related findings. This affects your negotiation position - in other words, they really can't move on to another buyer if you walk and conceal these issues.

Mold and serious foundation issues are not minor repairs — they’re structural and environmental red flags. If the true repair cost is closer to $30,000 and the seller is only offering $5,000, that’s a significant gap. Foundation problems can worsen over time, and mold remediation needs to address the source — not just surface cleanup. The bigger questions I’d ask are: • Has a structural engineer evaluated the foundation? • Is there a written remediation plan for the mold? • Will you be comfortable financially if costs exceed estimates?

That’s a tough spot to be in, and I’m sorry you’re dealing with that kind of pressure. Situations like this can feel overwhelming, especially when you have a timeline because your current home has already sold. Issues like mold and foundation problems can sometimes be manageable, but they’re definitely things you want to understand fully before moving forward. The key is figuring out how serious the issues are, what caused them, and what the true cost of repair might be. With mold, the cost and complexity can vary quite a bit depending on how widespread it is and what caused it. If it’s a small, localized area from something like a past leak that’s already been fixed, remediation can sometimes cost $1,500–$5,000. However, if the mold has spread into drywall, insulation, HVAC systems, or structural areas, professional remediation can run $8,000–$15,000 or more, especially if materials need to be removed and replaced. It’s also important to address the source of the moisture, otherwise the mold can return. Foundation issues are often the bigger concern because they can affect the structural integrity of the home. The cost depends heavily on what’s happening—whether it’s settling, cracks, drainage problems, or movement in the foundation. Minor crack repairs might be $10,000–$25,000, but more significant repairs such as foundation stabilization, piering, or major structural work can easily range from $100,000–$1500,000+, depending on the extent of the problem and the size of the home. Because of that range, many buyers choose to bring in a foundation specialist or structural engineer for a more detailed evaluation before making a final decision. That kind of expert opinion can help confirm whether the estimate you received is realistic and whether the issue is something that can be reliably corrected. As for whether it’s a red flag, it really comes down to risk tolerance, the quality of the repair plan, and whether the numbers still make sense for you. Some buyers move forward with homes that need repairs if they understand the scope and feel the price reflects the work required. Others decide it’s not the right fit, especially if the costs or uncertainty feel too high. The timing pressure you’re under is very real, but it’s still important to make sure you’re comfortable with the long-term investment. A home is a big purchase, and unexpected structural repairs can become stressful if they’re larger than anticipated. If possible, it may help to pause and gather one more professional opinion on the foundation and mold remediation costs before deciding. Having clearer numbers could make the decision much easier—whether that means renegotiating, moving forward with confidence, or choosing to step away and find something that feels like a better fit.
