I just negotiated an extension to a lease in Boston. The landlord eventually conceded 2 free months of rent on an extension of less than a year, but absolutely refused to budge at all on the monthly rent amount.

Their adamant defense that the unit was already at "market price" was just such absolute bullshit that I nearly moved just on principle. Lucky for them, I hate moving even more than I hate the landlord.

The average monthly price on my extension is about 11% below my average monthly price on the old lease.
