It's a really handsome house, as is. I agree about putting your money in landscaping. Take out the "nose" bush (doesn't it look like a nose below the two window "eyes"?) and have someone help you maximize the impact of your $$. Add some large pots with colorful annuals...LARGE pots! With a larger budget, I might repaint to a more interesting color, but maybe next time it's due look at some other colors. I can't really see the furniture, but if it looks nice, maybe just add a couple of umbrellas - maybe you have them but just not out for this shot.

One other thing, as far as plantings go, eventually you need to identify what the trees and shrubs are on your property. That's key to deciding what to plant around them, and how to care for them to keep them looking their best. For example, if one of your trees has a wide, shallow root system, that is going to determine what can grow under it and how to plant it. Some plants express toxins from their roots or leaves that inhibit the growth of other plants around them, etc. You may never get lush growth, depending on what the trees are. Something to think about as you progress. I wouldn't repaint the house, save the money for more significant improvements, and I'm wondering if you have vinyl siding which would make that problematic anyway. Landscaping is artfully solving problems, which to me looks like you need a stoop and as long as you're at it, some type of awning or extension of the roof to cover the stoop so that when folks knock on your door when it is raining they're not standing in front of where all the water is going to run down off the roof! It looks like you have a groovy walkway already no? After that, I also second the suggestion for a little picket fence to visually block off your lake side from weekend gawkers driving around the lake. Not necessary but would be nice. Doll it up with plantings if you like. I am totally jealous, I would love a little place like that. One quickie suggestion, to add color and contrast to your hosta beds out front, try astilbe, or various ferns, and various types of heuchera. The classic combos. Also European solomon's seal and lilly of the valley for spring scent. Sweet woodruff makes a good groundcover in shade, as does vinca, the old standby, or ajuga. For spring color, jacob's ladder or virginia bluebells or some type of wild geranium or phlox. Throw in some turtlehead and bottle gentian for summer and fall blooming. Keep it simple, don't plant all of these, they are just suggestions of easy to grow shade garden plants. You want to enjoy your time at the lake and if you don't love to garden you want low maintenance. I'm not sure if they'll grow well in your zone, but azaleas and rugosa roses are classic landscape shrubs. Any of the viburnums would give you beautiful white blooms and low maintenance UNLESS you have a deer issue. If so, they can be grown but need protection. But if your hostas are still alive, the deer may be under control already.

You need some earthy tones to help it blend into the natural landscape instead of sticking out like a big peach. For the WALL color I would suggest Benjamin Moore Shark skin (2139-30) with the trim or accents (Deck?) in Horizon Grey (2141-50) pictured here: The shark skin on the wall has a slight earthy green/brown tone to it. It will go nice with the stone.

If the windows with the view are a bedroom and bathroom, does that bathroom have another exterior wall in which you might add a window so any escaping sounds and smells from the bathroom do not open onto the deck? Have you considered sliding glass doors in the bedroom and/or (if the floor plan enables it) changing around the purposes of the rooms so the bedroom by the deck becomes a more used room .... such as could a dining room become a bedroom and the bedroom become a dining room? and/or build another bedroom and bath upstairs above the bedroom and bath on the main floor so the deck side bedroom might become a bonus room/den? Adding a downstairs entry facing the "front" (photographer) could be a good idea, depending upon the layout of the home. However, if the current main entry is beneath the deck, you might consider turning the garage into a sun room or screened porch that wraps around to become the entry unless you actually need/want another opening facing "front" (photographer). Do at least first consider what that would do to the interior of the room in which you're adding the entry. Does the room lend itself to that change? What side of the house is north/south/east/west -- will that impact your decision?
