NS = no subham
WS = with subham

kim:
total paid: $2000
total outstanding: $1200

nick:
total paid: $5200
= 4.33 NS months = 6.5 WS months

>>for 2 months we owed $1200 per month before subham
**NS months**
total paid ahead - two months of $1200
5200 - 2400 = $2800

*it's been ~1 months since subham moved in
**WS months**
$2800 remaining - $800 = $2000
= 2.5 WS months remaining
=you've paid until the start of december (lease goes til mid jan)
="pretend minus" the month i owed from the first month when i got fired and couldnt pay
=the real estate should think weve paid up to the start of november so fuck knows how but theyve fucked up their numbers and turned my outstanding $1200 into $400, unless you've made a payment you don't remember, so check that.
=if you pay 6 x $200, that's your lease done and dusted, bar a few extra days on the end (i think, check my shitty maths lol)
