An old house can turn into a money pit, but age alone does not make a house too expensive to keep. A 100-year-old home with a solid foundation, good drainage, sound wiring, and a recently replaced roof may demand less attention than a much younger house that has suffered years of neglect.
The real warning sign comes when repairs stop solving individual problems and start revealing a larger pattern. When the roof needs work, the plumbing keeps failing, the electrical system needs an overhaul, water keeps finding its way into the basement, and every contractor seems to uncover another surprise, the question changes from “What needs fixing?” to “Does keeping this house still make financial sense?”
