@Jared P.Quickbooks is an accounting/bookkeeping software that is used to track your data(income/expenses/assets/etc).If the property types are organized in a separate entity type, I would have them in two separate files.If they are not in a different entity type, you may want to use the "class" function within quickbooks to distinguish the asset classes.With that said, you may want to still operate them in two separate files if you find it that both businesses are too unique to another.

Prefer integration with airbnb automation software as well. 

The blog has numerous tutorials, and you can copy the examples from the blog posts into your own account to play with them.The software was developed by a friend of mine that also happens to be a Realtor that focuses almost exclusively on working with investors.

The alternative is to hire a full time onsite manager capable of performing all the duties of management, home sales, managing maintenance and repairs, and the implementation of software systems and processes that will eventually have the park running like a Swiss watch.
