Hi there- I'm a newbie so please be gentle! My husband and I are looking for a home (first-time home buyers). The area we like is full of older homes (early 1900s) and often have only a single bath. We would like to know when we look at the houses whether it is possible to add a second bathroom to them. Are there things we can look for that would help determine the feasibility of this? Or are there "right questions" that we could ask. It's a competitive market and so there is usually little time or opportunity to ask for professional advice before committing to a purchase.
