OP your house has so much potential
but its tired and needs a lot of tic which is going to cost, so the price is important and when I can buy a house round the corner (so to speak) for 25k less..
I would want the master bedroom to have a loo on the same floor, so would wonder why their is a shower but no loo? not enough room or another reason? As the window could be changed for a Juliet balcony
the kitchen lounge and sun room could all be open plan and give a feeling of space - at present there are no clean lines when you look at the phot from the front of the house to the back. You may think this doesn't matter but it leads to the house looking tired and for a house that is 20 years old doesn't give the modern look or add character
The house hasn't been cared for, the downstairs loo (yes I did notice you do have one) is really sad looking.
what would I do to sell it
paint the house and doors, all of them off white (including the louvered doors in partial blue) replace the carpets
make the kitchen look like its used
paint the utility door to the garage and dress the utility
or reduce the price by 30k and get it marketed as a projected
get planning for an extension across the back of the house
really like the dinning area vibe
