Here’s a great infographic about adding a bathroom.
In communities North of Boston, its common to see many 1 bath homes. While its generally not recommended to sellers to add a bath simply for the sake of re-sale, for buyers, sometimes its worth taking a look at 1 bath homes. Even if the search criteria calls for 2 bathrooms, some 1 bath homes have the potential for a 2nd bath, and an oppurtunity for buyers to get a return on their investment. In a low inventory market this gives buyers more opportunities, while staying within the same budget with the added benefit of enjoying a brand new bath.
