On average, a concrete foundation lasts 100-200 years. However, an extremely well-built foundation could last 400+ years, and a poorly-built foundation might start to deteriorate after only 25 years.
Yes, you can live in a house with a foundation problem, for a period of time. However, you shouldn't. Foundation problems worsen over time and will cost more to repair if you wait. In some cases, a foundation issue left unrepaired can develop into a problem that costs tens of thousands of dollars to fix.
Foundation issues are fixable for the most part, but they may become irreparable if the problems have been going on for a while. Since every situation is unique, it's hard to make broad generalizations about when to walk away from a bad foundation.
While you may see potential in a property with foundation problems, there are circumstances where the wisest decision is to walk away. For instance, if the foundation issues are associated with a severe structural problem, such as a sinking or shifting house, the repairs can be quite complex and expensive.
It is generally considered safe to continue living in a house with foundation problems. However, it depends on the severity of the issues.
It may make a lot of sense to walk away from foundation issues in a home if the cost of repairing the issues is more than what the seller is willing to compensate by lowering the home's price, or if the scope of damage and repairs is over your budget and time-consuming.
Basic Structural Damage – $5,000 for minimal structural repairs like small cracks, shallow foundation cracks, or loose stones. Average Structural Damage – $10,000 for more advanced structural repairs, including major crack repair or foundation repairs with underpinning.
Foundation repair costs can vary widely, but on average, homeowners spend around $5,017. However, the typical cost range is between $2,180 and $7,854. These numbers can fluctuate based on several factors, including the type of foundation, severity of damage, and local variations.
While foundation issues can cause major problems, the likelihood of your home collapsing into a pile of rubble is extremely low. What's most important to understand is that foundation issues can cause significant structural damage to your home.
If the house needs significant foundation repair that you don't take care of, you're likely to turn away a large pool of buyers and attract a group of house flippers who want a deep discount on the price. Foundation issues can reduce the sales price by 10% to 15%.
If ignored, foundation problems lead to severe structural damage. As the foundation shifts or cracks, your walls start to crack, floors become uneven, and doors and windows stop functioning correctly. Your entire home becomes out of alignment. And over time, this can compromise the stability and safety of your home.
Dwelling coverage, or Coverage A on your homeowners insurance policy, will likely cover foundation damage caused by covered perils. If the foundation damage is due to negligence, your insurance won't cover the repair cost.
The Bottom Line: Your Lender Won't Ignore Foundation Issues, And Neither Should You. Foundation issues are serious and can't be ignored, no matter how minor they may look and how much you love the house you're trying to buy. Even if you're willing to overlook them, your lender won't be quite so accommodating.
Yes, usually, you can live in a house during foundation repair. Minor repairs don't require you to leave your home. Homeowners often don't even need to vacate their homes during major foundation repairs like underpinning.
Using this simplified model (30-40 years of essentially no losses, followed by a constant decay rate), we get an expected house lifespan of 100-300 years. There were around 27.5 million homes in 1920, around 9 million, or 33% of which still exist. This is less than the bottom of our lifespan range implies.
Cracks wider than 1/4 inch. Foundation settling or sinking. Structural issues such as bowing walls or uneven floors. Water intrusion problems.
Here's some good news: Foundation issues don't necessarily mean you need to walk away from a home you're interested in buying. However, you should exercise caution and not rush into a sale.
Houses with foundation problems usually aren't in danger of collapse. Most houses become unsafe to live in because of a sudden and catastrophic event, usually a natural disaster. If that happens, you'll know about it. The truth is, many people live in houses with foundation problems without realizing it.
Water in the soil around a home puts pressure on the foundation that can cause cracks, leaks, and structural damage.
Ultimately, foundation repair is an investment in your home's value and marketability. Foundation repair may not directly increase your home's value, but it does enhance its appeal and helps sell it closer to its actual market worth.

Home Equity Loan or Line of Credit
Home equity loans and home equity lines of credit (HELOCs) are two popular ways to finance major home improvements, such as foundation repairs. But in order to be eligible for these financing options, you need to have enough equity in your home to serve as collateral for the loan.
Home insurance may cover some foundation repairs, but whether there's coverage depends on what causes the damage. Sometimes the event that damages your foundation isn't covered by your home insurance. When that happens, you're most likely going to have to pay for repairs out of your own pocket.
Conclusion. Lifting a house to replace the foundation is a major investment, often costing between $30,000 and $100,000 or more, depending on the size of the home, foundation type, and local conditions.
