There is a small chance that I will not sell it for a long time. 

I think they call that a long term rental. :)Seriously, it will be treated like a LTR.

My options usually include the all cash/quick close to flip myself, listing it (as an agent) but also offering the seller to do a JV flip together, I could wholesale it, offer to buy it myself for a BRRRR or other long term personal investment, etc. 

Your income from the long-term properties is considered as your personal income so it shouldn't be so impactful.

I have found a potential short term cabin in a great spot that is only wanting to have someone assume their current loan.

Occupied by Past Owner in one unit, the other unit is empty.I have hired a property Management company to complete eviction - Upon receiving Eviction notice, Past Owner / Tenant went to the Property Management office and insisted that she still owns the property, refused to sign a lease, and stated that she won’t pay rent for her own property.Property Management company stated that this will not be resolved without going in front of a judge and told me that it can be filed at the end of the month.How long with this process take?

I'll start out with asking what your long term goals are.

Lenders:Several lenders offer investment property loans in Columbus:- LendingOne: Provides short-term mortgage loans for property purchases, refinancing, and rehabs- Longhorn Investments: Offers hard money loans for Columbus real estate investors- Longleaf Lending: Provides 30-year rental loans for long-term rental property investmentsFor BRRRR and fix-and-flip strategies, consider hard money lenders.

If I am not mistaken, the reason why it would take so long to get the deed after a tax lien foreclosure in Alabama is because, the court will also quiet the title for you.
