What Homebuyers Should Know

When evaluating homes in St. Tammany County, the purchase price is only part of the total cost of ownership. Safety-related remediation costs — including water filtration, lead pipe replacement, radon mitigation, and flood insurance — can add thousands of dollars to the first-year budget.

Homebuyers should request a water quality test and review the ZIP code safety report before closing. Properties in ZIPs with more violations or older infrastructure may require higher remediation budgets. Check your specific ZIP code on ZipCheckup for a detailed cost estimate.

Understanding the Equity Trap

An "equity trap" occurs when required safety remediation costs consume a disproportionate share of home equity — typically above 15% of the home's value. This is most common in areas where home values are lower but environmental risks are elevated.

In St. Tammany County, remediation costs range from $1K to $3K depending on the specific issues found. For a home at the county median of $254K, these costs are manageable. However, homes at the low end ($184K) may face equity trap conditions where remediation represents a significant financial burden.
