Hi
I'm sorry to hear why you're moving. Have you spoken to a manager at the bank? I think it's really worth pressing the issue because the way things are, they're going to have to make allowances.
It's a nice wee house.
The photos are atrocious though. I presume your kitchen is actually white, not a peach /pink?
The lounge definitely needs rearranging & look at the colours on those photos. They're very different. The one that's green is unpleasant. (And yes, move some of the baby clutter fir the photos. Lots of people completely lack the ability to see past stuff).
I'd definitely paint your bedroom wall, a Navy will relatively easily cover the green and get a more neutral throw. Though that one might look ok against the navy.
The bathroom is a bit dated, but that's ok, it looks clean & totally serviceable and I'd far rather that & put my own choice in later than pay more for a house with a 'done' bathroom I'm not personally keen on.
You need a nicer weather photo of the garden.
You NEED. a photo of the downstairs shower/toilet. Lots of people will look through the photos & discard houses that don't appear to have what they're looking for.
But as I say, I think you'd be far better off talking to the bank, looking in MSE, calling a few brokers & doing your best to get a better mortgage on it & staying put. Selling & buying is expensive & you REALLY don't want to end up renting.
Best of luck
