What do I need to disclose when selling a home?

You must legally disclose everything you have knowledge of, regardless of the time frame.

Texas has required disclosure forms for property conditions. A good real estate agent will be familiar with these forms and insist you fill them out truthfully and fully.

There should be clarity on any issues with a home. Disclosure is the name of the game in MA and I would assume it would hold true in any market. Fail to disclose could cause massive legal issues. Disclose .. disclose ... disclose.

The rule is disclose, disclose, disclose. Generally, as homeowners, we are aware of any defects in or outside of our home.
I managed litigation for real estate errors and omissions insurance. The most common case was based on a failure to disclose. I absolutely recommend disclosing anything including any insurance claims whether they were 20 years ago. You don’t want to find yourself in a lawsuit.
