How honest do I have to be in my disclosures?

When it comes to disclosures. It is better to disclose disclose disclose. Its also better to mark I dont know instead of yes or no if your not sure.

Seller’s disclosures are to be completed to the best of your knowledge. It is assumed that you may not know the exact date something was updated. Perhaps you know the year but not the exact date. You may always mark “unknown” however I have seen this overused and it throws up a red flag to me as an agent. Just keep in mind, to the best of your knowledge. If you truly don’t know, mark unknown. Good luck with your sale!

It would be best if you had a professional look at it for evaluation. Then you are not guessing. Are you looking to put your home on the market?

Best to mark "unsure" and add notes than make a firm statement of yes or no, as you do not want to open yourself up to any scenario where there is wiggle room to get out of the agreement. This along with other details should be discussed with your real estate expert when listing your home. They are there to protect you :)
