So my mother has promised to give me her second property. There's an old ranch style house with an acre of back yard on the property. She rents it out to a family right now, but in a few years i'll be wanting to make my move on the property.... So my question is, would it be cheap to build a new house on land that i already own, rather than buy a house on land i don't own? I plan on tearing down the old house since i don't like it at all...
