my favorite is Synthesis by Sharpline, you can see the details here.  

That being said I AM PUMPED to get rolling in that field which is night and day different than being a research chemist in synthesis and applications. 

To name a few: Syndicated Deal Analyzer by Michael Blank, Robert Beardsley's Deal Analyzer (that one you can pull for free), Rod Klief's deal analyzer (if you sign up for his upcoming 1-20-2023 boot camp I think you might get it as part of the library package but not sure), Synthesis, Justin Goodin's model.

A few paid ones include Synthesis, The SDA - Michael Blank, and ThinkMultifamily's model.I've heard Udemy has an inexpensive course, but I haven't investigated.

You can check out Synthesis, Michael Blank's calculator, or the free one offered by Joe Fairless here.

By contrast, the IRR underwrites cash flows which synthesis into a periodic cash return.
