Anthony, nice setup! To your question about the rental mortgages, you haven’t said what interest rate you are paying. As a start, if you are paying more than the risk free rate (Treasury bills) which you probably are, then a true apples to apples comparison would be yes, pay off the mortgage. But, if you are comfortable taking more risk, you have other options to invest in which you *hope* will yield you more over the coming years. You also didn’t say whether the rentals generate net income and if so, how much? What is the implied rate of return on the equity you have invested in them? If you pay the mortgages off, you’ll have even more equity tied up, will the extra net income make that worthwhile? Maybe you should use the money to buy more rentals instead, if purchase opportunities still exist in your town. … this is less of an answer than a framework to analyze the decision, hope it is helpful.
Quick story: Remember that $1.18 I found in the couch? Even when that increased to $30 to $50 a day, it still wasn’t enough to live on. So I looked for other options. In August 2008, after people started to know who I was and how I could help them pass the LEED certification exam through my blog, I wrote an ebook. It included all the information I knew about passing this exam, and I sold it on my blog for $19.95.

On August 4, 2003, Brad and Karen Murray’s marriage ended. They continued arguing over their assets for another four years. Brad worked as an independent broker for Ameriplan – a marketing company specializing in providing discounted rates on services related to healthcare. As part of his job, Brad sold monthly memberships to Ameriplan’s discounted health plans. He also recruited other brokers to do the same.
What’s also really important to realize here is that when I took the exam I was teaching people to study for, I didn’t get a perfect score. In fact, I didn’t even get close to a perfect score. I passed. But I also knew a lot about this exam—way more than somebody who was just getting started diving into studying for it. And it was because of that, because I was just a few steps ahead of them, that they trusted me to help them with that information. To support this, I provided a lot of great free value to help them along the way. I engaged in conversations and interacted in comments sections and on forums. Most of all, I just really cared about those people, because I struggled big-time with that exam myself.
Managerial accounting defines residual income in a corporate setting as the amount of leftover operating profit after all costs of capital used to generate the revenues have been paid. It is also considered the company's net operating income or the amount of profit that exceed its required rate of return. Residual income is normally used to assess the performance of a capital investment, team, department or business unit.
