How about adding a trellis to the house either down the side or across the front with a small retaining wall that runs level. The retaining wall would only need to be slightly higher than the the rise of the ramp and could be hidden by landscaping. The retaining wall could also be designed as a planter. The trellis could have a vine that would create nice visual appeal. If a hand rail was needed it could be a simple rail similar to that attached to a wall on a stair case so it would have minimal visual impact.
If you chose to stay in your current two story home you could also retrofit the home with a personal elevator. We have included elevators in some homes we built in the past. They start at around $20K and are about the size and look very similar to a small walk in closet. Could be an option to allow you to remain in your home.
If your current home has 3 steps with a 7" rise each that's only a 21" rise. It shouldn't be that difficult or expensive (unless lot restraints are an issue) to regrade the lot. Heck if you are going to remodel another house is it out of the question to retrofit your house? Don't forget the move alone could cost something so factor that in as well. Unless of course you don't want to stay in your current home?
Just thinking.
