I am 36 (i consider that young :), currently working overseas with my former NCC primary home now rented. I still owe 400K on the property which likely appraises today at 950K or so. I bought in 2010 and have struggled to refi as it is very difficult to close a loan when you work for a non-US company overseas (despite having verifiable tax returns, pay stubs, etc)… so my current loan is 4.75% and payment 2600 / month, renting at 4K / month. I am thinking about paying this off to #1 assure my family a roof over our heads should we ever need it, #2 call me conservative but a guranteed 4.75% for me is a decent return. With the property paid off worst case i have an asset cash flowing me almost $3K / month and the security of a beautiful home in a great schol district to live in should we ever need it, with the sole pressure of generating enough income to pay for property taxes, bills, and food to provide a decent life for my family. This for me is compelling as I know life throws punches and i may not be able to generate the cash i can today in the future.
