For me, the opening shot doesn't look great, tbh.
Way too much grey foreground. I can't do it on this computer, but you could try it yourself - just crop the left hand side of the frame so you include the greenery and the bottom up to there lavender bush and you'll have a much nicer first pic for ppl to see.
Ideally, take it again with your car on the drive, but so you can still see the garage.
I think you'd have attracted more interest with that as a front-of-house pic.
Is it a 70s house? I like that kind of period, tbh - I know people who've added wood and other things to the exterior to give it more of an aesthetic appeal - you might mention that as an option to people who perhaps don't appreciate the plain/clean optics...?
You have some nice stuff in there - love the colour of the sofa. Like the garden too.
Fridge freezer a bit odd as other ppl say, but...aside from what I've said about the first photo, it's only ever about the price.
Change the pic and see what happens in Feb/March - but enjoy your last Christmas there though...looks like a nice family home for a nice family to enjoy.
