List of lenders who don’t require HOA to carry flood insurance?

[Sofiya Cherni]

Hi, sis is selling a condo rental, the sale fell through because buyers' lender requires for HOA to carry flood insurance (which the HOA doesn't have and don't plan to have in the future) as the property is located in the flood zone (in Scottsdale, AZ where it rains a little every 100 years, give or take). I'm looking for a list of competitive lenders that don't/won't require HOA to have this flood insurance so that sis could pass on to buyers to save some time. Any advice on how to deal with this obstacle would be much appreciated!
