Remove the skirting and have it installed over the floating floor. For the little amount of work it takes to patch and paint / touch up the skirting, it gives you a professional job not a DIY job.

Scotia would not be my choice either! In kitchens the trim/bead is a dust and grime gatherer and just makes the task of cleaning that bit harder. I use a second/new kicker to cover the gap and tuck the new board under the end panels where possible. Having said that the jointing they have done looks very tight! Hard to change it now unfortunately.

I think you first need to look at your general area and the size and style of homes there. Attend open homes and check what others have done or not done and the price they sell for. Even look at returns on leasing according to the style and condition of the house - Estate Agents will happily help you with this. Depending on movement in the market around you, this can take time, so be patient it will be worth it in the long run. You can be a little adventurous with any upgrades when people are upgrading and renovating all the time, just don't to too far with what you do or how you do it to avoid overcapitalising or limiting your market. I'm also finding a lot of buyers are resisting ultra modern homes, they like modern but not too OTT so beware of adding features that may not appeal to everyone. Again, studying the type of people in your area will give you clues as to the type of people who will want to buy into the area, the type of lifestyle they have and what they want in a home. The trend to putting ceramic tiles in kitchens and casual living areas is fading and they are much more expensive to take out and replace. Definitely not a good idea if you decide to lease as they can be broken or even pit if not cared for properly. I'm presently looking to buy a new home and I'm seeing too many homes where tiles have been destroyed which is going to be a very expensive exercise to replace. If you are going to lease, keep things simple. I think Oklouise has nailed a very simple plan although I would take the toilet from the laundry, some space from both the kitchen and living area and put a separate powder room beside the laundry so you can make it more attractive for guests. One slide-in door from the hall opening to a lobby with the laundry going off one side and the power room the other, would take care of any odours or noise. The washing machine and dryer will make noise too. I don't think I would attempt to create a master suite downstairs, I know many who agree with me on this, but dividing bedrooms over two levels tends to create "fractured" families. You certainly won't want to be running up and down stairs all night to a restless or sick toddler. It then becomes too easy to have the toddler in your room and that can be a very hard habit to break. Three bedrooms are sufficient for many people so a simple upgrading of the bathroom, wardrobes (if necessary), flooring and window covers should be all that is necessary for the upstairs. The emphasis these days seems to be more in living space and entertaining especially when it includes generous outdoor areas , so I would make that your priority.

Price check everything before deciding. Many people take too much advice from salespeople who want to sell you just what they have. A solid timber flooring isn't really that much more than a timber floating floor. I've found the cost difference is having the solid floor sanded and polished, oiled, etc. only. There is some quite expensive floating floor options and some really cheap ones. Buyer beware!
