Does Prepaying the Last Month of Rent Lock in the Rate?
<p>Suppose A rents a property to B for six months. Initially, the rent is $500 per month, but A requires first and last upfront, so B pays $1000 plus deposit to move in.</p>

<p>During month 4, A raises the rent to $550 (following proper procedures). Does B have to pay the difference ($50) for the last month?</p>

<p>Assuming this is rental of a residential property, the situation you describe can't happen.  Oregon Revised Statutes 90.323(3)(a) prohibits raising the rent during the first year of tenancy.</p>

<p>If this is a non-residential property, it will be spelled out in the rental agreement.</p>
