A matter of economics

If you've never seen the Robb Report Exceptional Properties magazine, it's worth seeing how the other half might live.  The images of luxury homes for sale are unreal (not to mention the prices)!  It seems unbelievable that any one needs (or wants?) 20,000 square feet of living space-and some of these offering are obviously meant to be second homes!  It's a real curiosity as well as a bit nauseating to imagine.
On a more realistic note, Mary Hunt's Debt-Proof Living newsletter contained a reader letter about how paying just $10 more per month on a student loan for 14 months reduced the payback period by 10 months.  $10 a month is much more feasible for us normal folks who don't live in a $20 million dollar home.  I'll never have an 'exceptional property' but I see a shorter repayment period in my future-that's always good news.
