Have you evear heard of people who paint their front door red when they pay off their mortgage? Do you think this guy just paid off his car loan?

This may be fine for your house. You are proclaiming to the neighborhood your independence from the bank. But don't catch yourself making the same proclamations for your business in your Internet marketing conversations.
I'm sure you're proud that you own your office building or have stayed debt-free for decades. That can generate a wonderful sense of pride with you and your staff. But keep it at that, inside company walls. Don't waste your time telling prospects how well you've succeeded. Instead, spend that precious energy engaging with their needs and showing the benefits and results of your product or service.
It's not about you. It's all about them.
