To some people a house is old and to others it is vintage. There are houses that were built in the 1950s and 1960s that are almost untouched by time. They still have the original owners too. I call those houses vintage. Other than the wall-to-wall carpet in shades of gold, green, or orange some of these houses are move-in ready.
I have found 50+-year-old appliances and furnaces still working and kitchen cupboards still in good condition with the original hardware that is vintage. We can still get parts for some of the appliances and hardware for windows and cupboards.
Some of those little mid-century ramblers were remodeled in the 1980s. Those houses are more old than vintage. Sometimes remodeling them again makes more sense than trying to restore them.
Old tends to happen because of neglect or “trendy” remodels. Vintage never gets old if you like vintage.
The houses in St. Paul are mostly old, historic, really old, and vintage. Historic is old but old is not historic.
