One of the reasons why it is important for you is so that you can provide this information to prospective buyers. Taxes and HOA fees are included in what is known in lending land as PITI, (maybe that should be changed to PITHI) to calculate the front end ratio when qualifying for a mortgage. I am sure the last thing you would want to have happen is to have someone go into contract, possibly even get a commitment, only to find at the end that they are denied by the lender because their ratio is too high.
Not sure what FREC is, but I am assuming it is some sort of Florida Real Estate something. I used to do loans in Florida, but have not for the past 2+ years, so I am not sure how they deal with the fact that properties are reassessed based on purchase price, if that is still the case.
