Claim 4: “The tax... covers people who own but do not live full-time in a house worth more than $5m or a condominium or cooperative unit worth at least $1m.”

DISPUTED

There is a contradiction in the value thresholds. Some sources (AOL, Mamdani admin. sued) state the tax applies to properties valued at $5 million or more. The claim mentions a $1 million threshold for condos/co-ops, but the evidence provided for this specific claim consists of general NYC Wikipedia pages that do not mention the tax thresholds. However, other evidence for claim 7 mentions a $5 million threshold for homes, condos, and co-ops, contradicting the $1 million part of the claim.
