Rental Property Flood Insurance in Alvin, TX?

Hello BP Family,

I currently live in WA and I am looking to buy an out of state rental property in Alvin, TX. It makes sense in terms of cash flow, but one thing that concerns me is that Alvin, TX is very near to water which might make it prone to flooding. My research also tell me that Alvin, TX can get heavy rains and flooding. But the agent that I am working with tells me that the property is in a No Flood Zone, so I should not worry about Flood insurance, but I couldn't find "No Flood Zone" for this specific property over internet. Any thoughts? Any websites which can reliably tell me whether a property is in a No Flood Zone or not?

Are there any other things that I should look out for before closing the deal? Thanks in advance.

Regards,

Ashish
