&gt; Old hands remember a time when Facebook offered a few hundred dollars for employees who lived within a few blocks of its old offices in Palo Alto. Landlords got wind of the situation and quickly raised rents to match, they say.<p>There&#x27;s a big difference between &quot;within a few blocks&quot; and within 10 miles (which includes 3 separate counties). Landlords would be foolish to raise rents just because one employer is giving a housing incentive.
