Answer:
A "blot" on a house title refers to a restriction or encumbrance that affects the ownership of a property. It can limit the owner's ability to use or transfer the property freely and may cause difficulties in accessing financing or refinancing options. Potential buyers face risks and uncertainties when purchasing a property with a blot, as they would inherit the legal complications and potential disputes associated with it. It is crucial to resolve any title issues before entering into purchase agreements to ensure a smooth transfer of ownership.
