I'm going to have to do some catch up reading to see where this is coming from. It may be in the policy releases that came out which I have not read yet. Another reason I may have not have run into the problem is the majority of our loans have surveys.
In one year, with the scenario you are describing, you will have to obtain a survey with the elevation certification. The cost should be passable to the borrower via your note and/or mortgage.
