If you installed the wrong house, act immediately to verify legal ownership and rectify the error. Contact a licensed real estate attorney to review property deeds, title records, and boundary surveys. Negotiate with the affected parties (e.g., seller, neighbor, or contractor) to resolve the issue through mediation or buyback agreements. If disputes persist, pursue legal action or file a complaint with the local real estate regulatory board.

The primary risks of installing the wrong house stem from legal and financial repercussions. In the U.S., approximately 5-10% of real estate transactions involve ownership disputes, with title defects being the leading cause (American Bar Association, 2023). A 2022 National Association of Realtors study found that 3% of buyers face significant issues like incorrect property descriptions or boundary encroachments, averaging $15,000 in resolution costs. For example, boundary disputes often arise from outdated surveys, with 30% of such cases requiring legal intervention (National Conveyancing Association, 2022). Proactive verification of property records and professional legal review can mitigate these risks. Additionally, state-level real estate boards report that 70% of post-sale conflicts are resolved through mediation when handled early, reducing litigation expenses by up to 60% (U.S. Department of Housing and Urban Development, 2023). Therefore, prioritizing legal and technical due diligence is critical to minimizing financial and legal exposure.
