I don't see any reason it would not. depends on the data.  

Whether it makes to sell the rental or keep it depends on your answers to these questions. the property is producing around $855 after property management fee, I have the same tenant for almost 3 years That's a little over $10k/year in cash flow, which is very strong yield for the price.

He has paid dependably, but last night he read my message and has not responded to the renewal.

Only difference is the $10K is in your bank and the interest starts so you are paying on the full $10K over how ever many years they offer.Lastly, depending on your first mortgage rate it may be best to just do a "Cash out refinance" becuase its over a 30 year mortgage and the rates are lower then both Heloc or Heloans. 

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

For newer loans with higher or comparable interest rates, the decision largely depends on personal preference—whether to transfer directly into an LLC or use the land trust strategy.

It depends on your market and how hands-on you want to be.

With closing costs, housing costs, agent commissions, my HELOC costs, I estimated about $20-$30k profit, depending on sale price.But, now I am thinking this would be a great BRRRR to learn those ropes as well!

Finding a good tenant in non-peak leasing season in Oklahoma is not for the faint of heart, especially depending on where the house is located.

Sounds like you are happy with the answers but here is something else to consider: NJ is a judicial foreclosure state so timeline to foreclose is multiple months at a minimum and could even be over a year depending on the tools you have.Is your lender a big institution or a smaller private lender?
