Good question! I'll try an answer and hope it's a good balance between accuracy and what I guess is your (and other readers') knowledge of astrophysics. [tl;dr: a neutron star (NS) and black hole (BH) in a close binary are practically guaranteed to "crash" into each other eventually. There seem to be lots of those binaries. Neutron star - black hole mergers (NSBH) from other possible arrangements (wider binaries, isolated individual NSes and BHs) will be vanishingly rare in "the local universe".] There are two principal branches in an answer to your question. First branch: there are probably…

Given that how common it is to find massive stars in multiple systems, it would be surprising not to find systems of compact massive objects that are remnants of these. OTOH, who knows about intermediate mass BHs and beyond. Aggregation of these multiple systems of CMOs? Let's look! - -- sec 3.5 and table 1, Duchêne & Kraus, https://arxiv.org/abs/1303.3028 multiplicity counts are all over the map: Eggleton & Tokovinin 2008 Guerrero et al. 2014 Lada 2006 but pretty much nobody thinks they're extremely rare.
