Is the final opinion of value ____________________ rounded? This means appropriately rounded for that magnitude of numbers. It might be acceptable to leave a final opinion at $54,500; but a figure of $554,500 or $1,234,000 might be rounded to the closest thousand or closest five thousand dollars.
You go along with the way the market thinks. In negotiating, would someone typically offer to pay $554,500, or would they make a bid of $550,000 or $555,000?
The same practice goes for rents. Tenants don't usually pay rents of $888 per month; they pay $850, $875, or $900.
