Owner is a licensed real estate broker in the state of Alabama.

I struggle with that myself.Insurance broker - I can introduce you to a couple of great agents, but they are not on Bigger Pockets, so I cannot tag them.

Firstly, well done for persevering and trying every avenue you thought would get you the data you needed.Most would have caved earlier and handed out there hard earned cash for old, saturated leads/records from the same prominent platforms which dump them pretty much when they receive them from either 1).the same large brokers AFTER the county has listed them on the county website or, 2). from the counties themselves directly AFTER the county has listed them on there own website, or, 3). from data scrapers on Upwork/Fiverr who scrape the data from those same platforms AFTER the counties/brokers sell those platforms the data being scraped by the freelancers.Anyway, rant aside you seem to of made the same mistake i made when I first started branching out away from providing leads to my original couple of clients i got from Upwork who wanted me to scrape data from court records in FL for pre FC leads.Simply, I didn't know where to look for the information I needed in states outside of FL.FL only allows the judicial route to foreclosure so I only needed to know/find/scrape the data from Lis Pendens documents for counties they requested.

Although we’re not a local bank or credit union, we are independent mortgage brokers with experience in financing options that consider rental income rather than personal income. 

When it's time to sell, I consult with multiple brokers, the experts who know their stuff.

Would you suggest an experienced attorney or is it best to work through a leasing broker?

You can also sell them on sites like paperstac, debexpert or others as well as brokers like Mission Capital, Rams or Phoenix.Depending on quality of paper and interest rate will determine sales price - also I would say self servicing can have a negative impact on the sales price as the major players in the space are not fond of self servicing. 

It would be a direct sale with no brokers involved. 

Sent you DM to a great agent/Broker that can shop for you. 

Like i got a recip to Mississippi for my CA / OR Brokers licenses and it was a whopping 13 question test I never figured out how they came up with thirteen questions its was almost like for me taking a drivers license test took me 5 minutes..
