When will my first mortgage payment be?

lowesm

Hello ladies and gents
Some help please if you can!

I'm also with Nationwide and I am due to complete on Friday 30th September! I've been having a little debate with my sister about the first mortgage payment as she completed on the 23rd September, so we're not sure when our first payments will be coming out and how much.

For me, I am on a 3 year fixed rate mortgage at 4.14%, our mortgage is for £115,150. Over 30 years
We paid a 15% deposit to get this. As I can see, LKMC01, you have your first payment coming out at the end of this month, 28th September.
When we applied for our mortgage, they asked us what date they would like our money to come out and we said the 1st of Every month, so am I right in assuming that our first payment will be the first of November.
Also, I cannot figure out how much our first payment will be.
We were told our monthly payments would be £559 a month, so on 1st of November, will it be £559, plus interest for Friday 30th....or as 1st November is a new month, will it be £559, plus the whole of October's interest and the one day?

We have enough money to cover the payment, whether it will be high or low, but I just want to get prepared! Anyone help? Sorry for the long winded post!
