One challenge to manage is being able to clarify for lenders on those rentals (if you have them) which amount of the premium should be paid for each rental so that they do not include the entire premium into their escrow analysis, inflating your monthly payment on that rental. 

If your interest payment is $8,125Your stocks have to make a dividiend of about $11,000 of which you would prolly pay 15% to 25% in federal / state taxes / NIIT.Assuming you will make a 10%-11% return is not guaranteed.You will also feel good about having a paid off property(relief).Furthermore, your credit score may go up with a paid off property.Best of luck!

I've paid for a handful of programs over the years from cheap to expensive and narrow-focused to broad-based. 

While I love the idea of eventually owning a paid-off primary residence, I’m debating whether it’s smarter to sell our current house and use the equity as a down payment on the new home or to keep it as a rental.

The question is will you benefit.If you already paid for the study, you might as well apply it to to the return.The next question is whether your accountant is properly applying it.You may want to consider working with a CPA who specializes in real estate taxation.

With buyers and renters relying more on online listings, I'm curious how valuable do you find virtual tours in showcasing properties?

if the note is currently in default and we can buy at at least a small discount, we may be able to restructure the note with no monthly payments - we would get paid all interest at closing when the property sells.  

They have since moved on to a new manager that is in close communication with me to get the repairs done and SDIRA is even offering to pay me the missing rent for December that the evicted tenant never paid.

In the past, I cashed out my 401K(Paid income tax + Penalty).

Almost like being paid to live there.
