If it has a bad odor, chances are something is wrong. Maybe there are rats living under the home. A bad smell invites bad energy. Bad odors don't just come out of nowhere. Maybe you're smelling rotting wood or mildewed leaks.
Bad smells can mean costly repairs.
You also don't want a house at the end of a street. The energy is bad. People are more likely to be nosy if your windows are open, and they're at a stop sign in front of your open windows than if they're just driving by. A home that is square or rectangular lot, this is the best. If it is another shape, a triangle, for example, with the point in the back, it is an indication that you will make very good money but you will not be able to keep it.
