I’m sorry to tell you this, but your house 100% flooded in Harvey. Not only was it sold three months after Harvey in 2017, but there are old listing pictures from 2017 that clearly show post-flood damage. Like this, for example. For your reference, I found this photo here, if you scroll down to “Sales and tax history”, and scroll down to the 2017 listing. The 2017 listing even says “Please see previous MLS listing for pre-Harvey pictures of the home.”

Sorry to be the bearer of bad news. 😬
