Back when I had a house mortgage and was trying to raise a family I never thought about the value of my property. My loan was thru the local bank. A couple times they said if you'll get a current appraisal on your property and update your file with us you will be eligible to borrow more money. After the first time of that I realized that my small hometown bank was NOT the partner that I had always thought them to be. They wanted me to be against the ceiling in regards to my debt ratio. As I gained ground, they felt like they were losing ground. Their loss. I continued to make payments and later double up on payments until payoff. Will never borrow money against the property again.
So, with all that said, the only reason to care where you are in regards to debt ratio is if you are intending to make changes, i.e., move, sell, buy, etc. The home/acreage I live on hasn't been appraised or valued since I built the house in 1979.
HEY, wait a minute,,,,,, maybe I'm a millionaire like those other guys and don't even know it....
