@John Thedford  as John states it gives you more arrows in your quiver and depending on price point and market.. listings now a days are simply money in the bank with no exposure to speak of.. :)also those that say being unlicensed will save you from the unconscionable profit.. that is not true someone can sue you for that just the same.. unconscionable is unconscionable regardless of licensure.And then it comes down to your personal compass on  morals and ethics when dealing with these folks.

My question is what happens to the extra 75k that was bid in excess of the outstanding 100k 1st loan? 

Since then I have set up various meetings with local retailers to buy excess inventory for pennies on the dollar. 

As mentioned by another poster try and fix the cheap and easy things about her complaints and see if she finds more, unfortunately unless the noise from upstairs is excessive there isn't a lot you or anyone else can do to fix that.

Yes, the interest rate if a little bit higher than a 10 year, but the lower payment helps me maximize my cash-on-cash return while allowing me to re-deploy excess capital to new investment endeavors.

In 2007-2009 a lot of banks reduced or closed unused lines of credit to minimize their exposure.

Less liability exposure as a limited partnerHere are several blogs to get you going:https://www.biggerpockets.com/blogs/10191/68640-wh...https://www.biggerpockets.com/blogs/10191/66365-8-...https://www.biggerpockets.com/blogs/10191/67979-po...Best of luck in your decision making process!

I may regret the decision in a year or 2, For now the MLS exposure is helpful. 

I have intended to put the cash flow excess back into the line so that I can speed up the pay off process.

This way I have exposure to most major asset classes.
