Goodness, I hope you’re up for all the criticism, we’ve all watched countless house makeover programs we are all “ experts”
Your house makes a great first impression, the lilac could be trimmed a little.
Clearly a conversion at some point, has removed the sitting room door, and amalgamated two rooms into one, leaving only the dining room door, but you have made a good use of wall space in the hall, with pictures, and the sitting room looks good with the sofas and pictures.
( the other house in Grantham someone posted, well the owners have astonishingly great taste, and are excellent home designers) but yours is good.
Unfortunately, as people have pointed out, your kitchen has a strange layout, with a rather plain back garden.
You can get away with your garden, with a few tall planters, and some lower planted colour, so you could take them along to your new home.
Instant drama and colour.
I once created a false flower bed for my sister at short notice with compost and bedding plants over lawn, to give a more balanced effect at the first view, so it can be done.
Ive no idea about pricing in your area, but think about how best to dress and furnish your kitchen, as this is often the deciding factor.
You have a long kitchen, just embrace it.
A long rug at one side and some judiciously placed side tables to cordon of one area for prep, may make all the difference.
You might even cut off the table part, finish the edge and add a dining table at the end of the room.
Best of luck
