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.

Not apples to apples but:Police chase claim brings mediationThe injury claim involved a man named Derek Guindon.Guidon was returning home from a weeklong job out of town with a coworker, Jade Thie, on March 1, 2012, when their Midwestern Mechanical van was struck by a Chevy Suburban driven by 19-year-old Kyle Jones.The chase continued for more than two miles along North Cliff Avenue and reached speeds of up to 80 miles an hour.Thie was killed when the Suburban struck the van at Cliff’s intersection with 60th Street North.Guindon was seriously injured.

Most of the time attorneys are completely aware of this and make the necessary adjustments on the closing statements.

An appraiser is not generally going to make an adjustment for that duplex down the street that sold.
