<prompt> Human: Im in a city that has certain apartments that are rent controlled, meaning that rent can be raised only once a year, at 3. Im looking at a new apartment, and while it is a very good price, it is not an apartment under the rent control ordinance. This means that after the lease is up, the landlord could literally raise it as high as he wanted. Speaking to the landlord, he gave a verbal assurance that rent increases wouldnt be unreasonable - that, for example, they usually wouldnt be more than 50. However, as I understand it, hes under no legal requirement to limit the increases, and as long as he gives sufficient notice he could raise it over and over by any amount any time.Would it make any sense to try to put a line into a lease limiting rent increases - e.g., just throwing an idea out there, to propose a clause similar to the citys rent controlled apartments, limiting him to one rent increase every 12 months, no more than 3 each rent increase? Conceptually this idea aligns with what he verbally says, so this could be a way to hold him to his word. But I am not a lawyer so I wonder if this would hold up, if this makes any sense to try to do, and so on. Would love to hear thoughts.  <response>: As long as the lease is active, he cannot modify its terms. When the lease expires, he can set a new price to whatever he wants. You can either agree to this or a rate you negotiate or leave. The landlord will not agree to rent control. No landlord would, thats why its imposed on them by ordinance.
