AITJ for not splitting the rent discount I got with my roommate?
My roommate and I moved into an apartment earlier this year. Rent is $2,400 total and from the start we agreed we'd each pay $1,200.
When we signed the lease, the landlord offered a discount if several months were paid upfront. I had enough money saved to do it, so I paid my half upfront and got around $900 knocked off what I would normally owe for the year.
I never mentioned the discount to my roommate because our original agreement was still $1,200 each and the discount only happened because I was willing to put a pretty big chunk of my own money down at once.
He found out a few days ago when he logged into our tenant portal to submit a maintenance request. Apparently the portal shows the full payment history for the apartment, and he noticed a credit on the account from when I paid upfront. He asked me what it was and I told him.
Now he thinks the $900 should basically be divided between us because it's a discount on the apartment, not on me personally.
My argument is that he didn't want to pay anything upfront and I was the one tying up my savings for months. If I hadn't done that there would've been no discount at all.
At the same time I kinda understand why he's annoyed because we're technically not paying the same amount for the apartment anymore even though we agreed to split rent evenly.
He says I should knock $450 off his rent over the next few months. I told him no.
AITJ?
TLDR: My roommate and I agreed to split rent evenly. I used my saved money to pay several months upfront and got a discount, but didn't split that discount with him. He found out through our tenant portal and thinks I owe him half.
