Was this from the agreement of purchase and sale? It sounds like the seller has the right to back out if he discovers that you intended to buy this property for personal use, not investment. But once the sale closes, the place is yours, and the seller can't do anything. Now if this house is a condo townhouse, there could be a condo board that has rules. Even if it's a freehold (i.e., standalone and not part of a condo and subject to condo association rules), there could be a homeowners association with rules you are subject to. I would confirm whether your house is a condo townhouse or part of a homeowner's association.
