When staging our house for sale I did the following:
Bought new bedding for each bed making sure that bedding matched the decor of the room.
I then bought new cushions & thows for the beds, I did the same for the sofa.
I cleared the kitchen sides of ALL clutter and kept only essentials out. I bought fresh tea towels that matched the kitchen and hung them over the oven door for a warm homely effect.
Bought matching towel set for the bathroom, this set was not used and only put out for pictures and viewings.
I boxed up and stored all unnecessary clutter, and binned or donated anything we weren’t going to keep. If you intend on moving there is no harm in getting some stuff boxed now, in fact you’ll be glad you did. Store this either in the loft or elsewhere that is out of sight.
I had a set of hooks on my bedroom door that usually had all sorts hanging from it, which made it look like we didn’t have enough space. I cleared the stuff and hung just my old summer straw hat so it didn’t look bare.
Bought a nice candle for each room which I lit before each viewing, but also blew out before the viewing, that way it’s not obvious and the smell isn’t too overpowering as you can never be sure what one person will like yet give another a headache.
Always put bleach down the loo and plot holes before viewings and opened windows just a tad in each room.
I did my pictures myself, agent did crap ones first so I ended up taking them myself and asking for them to be changed. Even when taking pictures during the day I put my lamps on and it made it look cosy and inviting.
There is nothing wrong with your house OP, it’s just in need of a bit of staging to make it extra tempting and stand out from others. I would declutter, hang curtains, get new matching bedding etc and I would pain those dark doors a nice crisp white.
