I think that is something that needs to be taken into account when purchasing rental property.  

We rank every active property by cap rate and sort the best ones to provide to our clients :) We have over 17,000 rental comps and account for all expenses on each property. 

Buyer's have to have at least 620 credit score and income below either 126K or 95K.

Acquiring an income earning property with high potential for appreciation for less than $20k out of pocket?  

In either scenario you want to make sure you account for the "cost" of the money in your deal analysis so you account for your HELOC or mortgage payments.  

I like Stessa with how it sets up separate bank accounts per each my properties I don't like that it doesn't give the option to have like maintenance request or repairs from the tenants.

So, understand that if you are planning on doing your own pm, then you are signing up for a part-time (hopefully only part-time) job, which you still should account for as a separate line-item in your #'s. 

Maybe I am misunderstanding or wrong in some way, but I would definitely reach out to your accountant, or a good one in the area as they can get a full overview of your situation and recommend based off what is required in Missouri. 

Get yourself an accountant who knows REI in your state, and pose questions to them.
