I would suggest you take out the cabinet that is to the right of the stove and use it elsewhere in the house -- perhaps in the bathroom or dining room with a hutch above it. Then, I would suggest you have someone install a lazy susan cabinet in the corner between the sink counter and the stove, meaning you would move the stove down a bit and have a small cabinet/counter top to the right of the stove. I would suggest you have the cabinets refinished in white and then paint the walls a pastel you like. If you would prefer white walls, then add white-painted crown molding and paint the ceiling a light neutral blue, such as Sherwin Williams Niagara Falls Blue. Then, I would suggest you choose a favorite accent color and use this sparingly in accessories like towels, pot holders, small vases or floral arrangements, and a valence above the triple windows. For a genuine 1940s look, you might have white ceramic square tiles with a rectangular red border installed as a back splash behind and above the stove. If you are replacing counter tops, I would suggest a light color such as white with a beige or light grey vein or striation for some sort of pattern. You might be able to find the same color and design in floor tile OR opt for a wood floor as another poster suggested.

If you are seeking a truly open feel to the floor plan you have shared, then using one material in the mail living area is the best approach to making this space feel truly open. Using a variety of materials on flooring chops up the space and decreases the visual footprint. I would suggest using wood, tile, or if you are on a tight budget laminated flooring for the living/dining/kitchen. Then use carpet in the more intimate spaces; bedrooms and possibly hallway. Save the tile for the bathrooms.

Low ceilings = flush lights. Before you purchase carpet get 5 or 6 agents round to value. Ask each for their opinion on what they think will appeal best. Ask them if you could get away with just laying underlay. For the wow factor make sure your budget is spent on items that you can take with you - think a huge 6fx3ft mirror, a bright modern art print, a mirrored console table etc. No need to splash out much just one item in a room or two to indicate wow. A patio table and chairs in the garden are also needed for the selling photos as they will help the buyer to see scale and the garden will appear more homely. A bowl of fruit in a chrome wire bowl in the kitchen will also add wow - stage with green apples and yellow lemons for example. So, to sum up the spend on 'wow' should be limited and only to what you take with you. As for the estate agents some of them do try very hard to give good sales advice so when you book them to value explain that the property is being flipped and you would welcome any ideas on how to present it. You may be surprised at what they suggest.
