The appearance does not change much - and zoning laws - occupancy rate laws - really preclude the home from having a major impact on the surrounding neighborhood.
This is becoming very popular with the aging population in America. We will start to see more community homes and assisted living on a smaller scale.
Do visitors ask "What is that?" or "What's going on down there"
If they ask, you can bet it has caught their eye and some people will undoubtedly not be excited about it.
If they never ask, it probably blends in enough to not be a disturbance, thus no negative effect on value.
Are you talking about the small ones that just have people living in a home within the neighborhood? Most likely not at all. Unless there are constantly people coming and going and crowding up the street so there is no parking. I can't think of any reason a buyer would have a problem with a house being used in that manor as long as it was taken care of as well as the other homes in the area are. Are you having trouble with one in yuor neighborhood?
