For 2017, I am adjusting my thought process slightly...

Refinancing Your Mortgage: When It Makes SenseImportant considerations for when refinancing is a good financial move.Refinancing your mortgage can offer a way to take advantage of low interest rates -- or, if your mortgage payments have become oppressive, an escape from adjusting rates, increased payments, or reduced income.

@Carol Venolia Hopefully the firs storm misses you, but if it doesn't, the insurance adjuster will want you to show proof of what ever you lost. 

The low total interest I'm paying each year combined with my curiosity to personally see the interest adjustment play out on a low principle balance changed my thinking.With a small remaining balance, the difference between the two approaches (maximize leverage v minimize debt) is too small to worry about.

If so, wouldn't it be better to use some type of adjusted number as (hopefully) a property does not turn over ever year? 

At 2x speed, this will take you about 60 hours, or over 2 full days.

I just finished negotiating the sale of one of our single family rentals and got me wondering if anyone has anything unusual they like to throw out in a counter offer to "sweeten" the deal without just lowering the price or adjusting closing costs.

I have been looking at the investment properties on their website and have been using my own adjustments to the numbers provided to see what the monthly cash flow would look like.

Perhaps that will change some day, and I'll want to spend all my efforts hunting for new deals, and will hire out all my work, and that's ok--I'll adjust when the time comes, but for now...I want to get my hands dirty. 

Others will have to chime in on a workaround to speed them up if possible.
