What are some important things to look for when scrutinizing an acquisition model?

I am trying to get better at building and analyzing acquisition models. I already know the obvious things to look for like whether the projected revenue/rent growth is too high, expenses are too low, etc. What are some other things that might not be as obvious?

Also, what are some things to look for that might increase the possible return of an acquisition (for example, the possibility of value added improvements).

Thanks for any insight!
