It must be beautiful and relaxing, but it also needs to be safe - from man-made or natural disasters. Trying to create an attractive rental from the property you buy that is sitting on an eroding cliff overlooking the ocean just won't fly, no matter how beautiful the view. Ditto if the potential for flooding from high tides or rivers is present.

People love to step out on a deck and not see anyone or anything except a great view. Even if the only view is the vast sky, the feeling people get is expansion and relaxation.

A property that is pet-friendly is usually on the ground floor, not on a busy street, and perhaps with a good fenced yard. If you are planning on buying a pet-friendly property, it is a good idea to have wood floors rather than carpeting.
