What the comparison can answer
The tool compares closed-sale counts, median sale prices, source-defined days on market, sale-to-original-list ratios, five-year median changes, and deduplicated Updegraff brokerage participation.
It cannot determine which neighborhood or property is the better investment. Rents, expenses, legal use, condition, financing, and the specific block still require separate evidence.
