If you are paying cash or seller financing and the numbers are there MAYBE. If you are getting a mortgage and requires flood insurance NO...for now.
Read up on Biggert-Waters. Personal residences were given a delay on premium increases. Anything out side of a personal residence: rental properties, vacation homes, commercial real estate are still going to continue to have premiums rise.
I can relate. I am in a community along the Ohio River where flood insurance claims are almost non-existent, but flood insurance is required for about half the town. I have to walk away from decent properties from time to time due to the fact that down the road I don't know if I could sell the property if I wanted to exit.
Until Biggert-Waters and the FEMA flood insurance mess is resolved I am steering clear.
Flood water is not the problem its the government trying to make up for misappropriated spending through FEMA. Example: my personal residence had a flood insurance premium of about $800 per year. Basement will get water through sewer when lots of rain mixed with snow melt. After Biggert-Waters my new premium was $2500 per year. After getting the elevation certification the premium went to $7,851 per year! Called the bank and told them they were about to be in the real estate business. Lender agreed to allow me to get insurance from a company in Florida for about $755 per year. I was zoned in WV the same as properties on the coast.
Here is an example of what you are dealing with under FEMA: https://www.youtube.com/watch?v=TTKufG1aofg
