I would like a warm mushroomy gray with darker brown/charcoal for the trim and window framing. Also, trim the bushes out front so we can see where the front door is...

Hi Geonin, the first thing that I would do is go through your house and de-clutter everything then ensure that everything is spotless and in good condition (pay special attention to the things that you know buyers will look at and things that are touched/handled every day as well as things like appliances and doors - make sure that nothing screams "repair bill"). The second thing to think about is paint and flooring - if your carpet is in good condition have it cleaned otherwise think about replacing it (expensive but poor carpet is seen as a big expense to buyers - particularly if its their first property). Paint your walls a colour that is as light as you can to make your property bigger but remember to tone it in with the carpet and keep your trims neutral (white/black) that will compliment your walls and carpet. Remember lighting and soft furnishings can change the whole look of your home too. During the open house/inspection phase - touches of home will help: smells like fresh perked coffee or baking are always inviting (you can boil some water with a stick of cinnamon and orange slices - just hide the evidence before you leave the house); if your inspections are late in the afternoon, turn on table and floor lamps inside and outdoor lights that'll add warmth.

What colour scheme did you end up picking?

Yes to all those ideas. I believe your cladding is unpainted concrete bricks (is it called Summerhill Stone?) in that (boring) fawn colour. My house is same but was painted by previous owners. It looks so much more up to date and the surface is lasting very well; no signs of peeling or flaking. So despite needing to maintain a painted surface, I think painting is the way to go. Alternative is a costly plaster job. Then the entrance - yes, wide generous steps onto a wide deck or patio, some vertical or horizontal slatted panels for protection or privacy as needed, clear roofing for protection and to allow light to the rooms. And paint the front door a vivid color to indicate the entrance. Just make this area feel generous! Dependent on the adjacent rooms and which direction the house faces opening up one or more of those windows into sliders or stackers would be great. Plants in big pots are good too, add colour and texture - and you already have some there. Good luck - I love the idea of turning an ugly duckling into a beautiful swan!
