A red flag in real estate is when a property has undisclosed issues or defects that could affect its value. This could include structural damage, plumbing problems, electrical issues, water damage, mold growth, and other hidden hazards. It’s important to thoroughly inspect any potential property before purchase to ensure it meets your needs and expectations. Additionally, be sure to research the area for any zoning changes or restrictions that may impact the use of the land or building. Finally, if you are purchasing an older home make sure all necessary permits have been obtained for renovations and repairs.
