I'd definitely do autopay.
Anecdotally I haven't really heard of a financial department person who's been able to correctly explain the discrepancies in the first month's billing on a resale contract. It also seems extremely laborious to try to get an accurate breakdown of various contracts or program vs HOA fees in one's account - so my solution is to wait until the second month and see if the monthly payment drops to where it belongs.
So from your past posts, it looks like this is a CWA contract. For 2025, maintenance fees ($8.13/k) plus resale program fee ($.73/k) are $8.86 per 1,000 points, so around $221.50 a month. If it doesn't come in around that number in the second month, that's when I'd get on the phone and not stop until I get some answers. But it might be a lot of wasted energy in the first month.
