Just a wild guess but I'd say purple leaf plum, Prunus cerasifera. Really too indistinct to be certain.

Was kind of thinking that. They are pretty much a terrible tree are they not? Lol

Depends on who you ask :-) I don't care for them - very inexpensive so extremely common (builders plant them in EVERY new development) and prone to a lot of disease issues. IMO, so many better choices, even with that coloring.

Not all purple plums are Prunus cerasifera selections. 'Newport' for instance, which often has a more attractive structure and aspect than the purple cherry plums. But whatever the kind is in your picture it has an unattractively thin crown and a forking trunk, that might split sometime - leaving the owner with half a tree.
