There are some ignores added to decorated property, since it's currently is not supported by mypy.

That's already a bit to much to specify all of the problems. I'll try to list those I identified.
There are some errors in qiskit/providers/basicaer/basicaertools.py due to the fact that Gate subclasses constructors are different from constructor of Gate.
There are also multiple errors in qiskit/providers/models/backendproperties.py due to the fact that qubit_property can return eithe dictionary or tuple depending on the runtime parameters.
There are some more that I'm unsure about fixes, help is appreciated.

Thank you for opening a new pull request.

Before your PR can be merged it will first need to pass continuous integration tests and be reviewed. Sometimes the review process can be slow, so please be patient.
