Like many virtues, patience can be taken to the extreme and become detrimental. Is there such a word for this?
Something that would fit in:
He's too extremely patient to ever see that$20.00 that he let his
neighbor borrow
The closest I've been able to come up with is "ambivalence", but that does not quite fit. "lazy" also fits, but the motivation is different.

If the style of legend and folklore is used, there seems to be a good match for what is being said:
"He has the patience of a wooden sculpture, so he won't see the $20 that his neighbor borrowed from him."
Probably the best is the often used phrase "the patience of Job", which is a biblical reference that is used for one with extreme patience:
"He has the patience of Job, so he won't see the $20 that his neighbor borrowed from him."
