One thing to be wary of with new builds OP is that they really are absolute bare bones and it’s not always true that they throw money & bundle deals etc at you!
We also bought a new build thinking similar, ready to move into (neither of us are very handy/DIY at all, so a reno would have cost us an absolute fortune in paying for labour), thought it would be exactly as we wanted it from day one etc. Seemed perfect! Online adverts showed some offers they had on, so we went for it. I don’t regret it because I do love our house BUT it cost us another £10k to get “our house” like this. They don’t come with any flooring, so where with a second hand property you could just live in it for abit and save for new carpets if you wanted to, you need to buy flooring straight away- that was £3k.
It didn’t come with any appliances, so that was nearly £2k for integrated appliances.
It didn’t even come with turf in the back garden, the back garden was literally a pile of mud, and to have the turf in was £900.
Not to mention the bathroom comes with no tiles (who would have a shower with just paint on the wall?!!!), again that was £900ish.
You only had a choice of 2 kitchen cupboards and 2 bench tops which would have been “free”- both ugly- so that was £1.3k to upgrade to ones we wanted.
Our bedroom & living room came with 1 plug socked as standard, we had to pay for more😂
And you have to pay all of that in advance, cash, so you need it on top of your deposit.
I still don’t regret it and I still love our house but it’s important to realise that a new build can still come with another £10k of payments on top of deposit x
