I convinced him to consider an owner finance deal and he agreed.

Perhaps also consider an earlier sale scenario and see how that impacts your investor returns.

It is a good idea to consider an option which allows you to collect rent much quicker than those others but still provides other rental management tools you might find valuable (again, not to knock Cozy or these other tools like Stessa because I know a lot of people love them), but since you have 24 units it may come down to the pricing (all depends upon what you want to accomplish).

A sort of related note too, you should consider an estate plan if you do not have one yet and you are a CA resident and own real property.

Also, most states don't consider an unfinished basement living space - so lead paint issues aren't considered a problem in an unfinished basement. 

One other thing to consider: An expense such as you are considering can't be written off in the year you pay it. 

Based off what they consider an acceptable return will then determine how much you get to participate or pay for the deal.
