How on earth can a prior first month rent be retroactively adjusted higher to today’s market rent. That would in essence leave a renter with unlimited loss potential. Your landlord could (in theory) tell you that your rent was now $6,000 a month and that you owed the difference between the market rental price years ago and what s/he decided to charge now (for the first month paid.)The retroactive adjustment is nonsense. Last month I get, but first month is garbage.
