Hi Caleb
Fingers crossed for you that your deal goes through as hoped! Looks exciting. How does it stack up in the analysis department? The guides and tools in the drop down menu of 'Education' above are great to run through again before you close. They're so helpful! Although you're planning to live in the property for two years, don't forget the adage "You make the most money on the day that you BUY" so keep the end game in mind.
I love design dilemmas and I'm either certified or fairly experienced in everything from staging to landscape design so these are fun questions for me. If staging can make such a difference to the speed and/or price of a sale, just think how much difference the overall design can make, so you're wise to take it seriously. Consulting with a college or design school would be a creative and economical decision, especially as you have the time. Houzz is a good tool as well but you might have to be predisposed to being interested and selective in that kind of thing. You need to keep your market in mind and not be over-influenced with great looking (and expensive) designs. Know your market!!! and ensure that's who you design for.
Even before you posted the photos, there were a few general suggestions that I hoped might be helpful. In the bathroom, the guiding principle is to always to try to keep the toilet where it is. You can spin it left or spin it right or maybe even move it an inch or two (a hassle) but design around it. All the modern tubs/showers are being tiled. The tub-surrounds of yesteryear are out. Focus on counter space and add storage wherever possible. Use the biggest mirror you can. Spend your money on trendy faucets and good lighting. They don't cost much more but pay big dividends. Keep colour neutral (beige, white or grey to continue the theme of the rest of the house - which should also be all in the same colour family). Use pattern and texture - not colour - for variety: translation: use more than one type of tile in the bathroom differing only in size, style or texture. Not all the same because you don't want your property to be labeled a cheap humdrum 'builder's special'.
For the kitchen - the owners before you set the stage for you to have the number one most requested item for the kitchen - an island. Ideally with a bar stool eating counter. I'm hoping you're planning on changing the cabinetry so you can move the stove closer to the sink (your building code will tell you how much space you need to leave between them - any local cabinet shop will be able to tell you off the top of their head). Moving the stove will allow you to 1) reconfigure to an L-shaped kitchen, thus creating more counter, cupboard, storage space and, 2) be a great incentive to replace the fan with another trendy 'must have' - a cool new hood fan. A tile backsplash is another component of the modern kitchen.
Adding an eating area is probably possible as well but is a little harder to explain or be sure of without floor plans etc. You'd end up losing your island but a pull up bar stool counter would still be possible.
So don't worry - you have a multitude of great options. Check and double check your numbers and then move on to checking out the competition in your market. It'll be fun.
