⚠ Cap rate of 251.9% is above the 20% sanity ceiling — verify the underlying price, rent, and expense data before trusting this. Cash-on-cash return of 924.5% is above the 50% sanity ceiling for a standard buy-and-hold — verify inputs before trusting this. Monthly rent is 24% of the asking price — this "sale" price looks like a monthly rent figure that was miscategorized as a sale, not a real sale price. Verify before trusting this listing.
