There are several popular programs out there, but personally I like Baselane because it's specifically for real estate investors so all your transactions will fit into the Schedule E you're going to need at tax time.

One person's unique could be my ordinary, and vice versa. 

A Debt Service Coverage Ratio (DSCR) loan for investment properties is often considered better than a traditional mortgage for several reasons such as: it focuses on the property's income rather than your personal income.

Personally, I am fine keeping my deal analyzer separate from the management of the properties I already own, but I suppose there is some value to one-stop-shopping.* Platforms that try to be all things to all people: This category is mostly Stessa and Baselane, both of which offer landlord accounting, self-management tools, as well as high interest cash management accounts. 

Someone with a great deal of tax experience has answered your question, I'd suggest you arrange a "paid" phone engagement if you don't have anybody locally.

@Jake Mercer would be a good person to reach out to and so would be @Fakaradin Floyd.

Anyway, just something to think about.At the end of the day you are personally responsible for the success or failure of your business so you need to decide how you want to run it.

Personally, I would look at the equity and would let that be my deciding factor.

In person, phone, email.

House hacking will also give you some personal "property management" experience.
