In the United States, appraisals are for a certain type of value (e.g., foreclosure value, fair market value, distressed sale value, investment value). The most commonly used definition of value is Market Value. While Uniform Standards of Professional Appraisal Practice (USPAP) does not define Market Value, it provides general guidance for how Market Value should be defined:

Please note: The discipline and specialty of each appraiser in this search are verified by ASA.

The Property Appraiser Association of Florida (PAAF) has developed a 3rd Homestead Exemption Tax Savings Estimator.  The estimator was developed to help voters determine if they will receive any additional benefit from the proposed 3rd Homestead Exemption (Additional $25,000) on the ballot for the November 6, 2018 General Election.  For additional information please see Understanding the 1st, 2nd, and 3rd Homestead Exemption.
There are new reports that scammers are filing fake quitclaim deeds. Unfortunately, these schemes have increased over the past few years. The thieves are preying on property owners and transferring the title to themselves and/or companies, which in turn sell the property, leaving the rightful property owner homeless. Stay vigilant and monitor the Property Search frequently for any changes in ownership.
Leased fee value – This is simply the fee simple interest encumbered by a lease. If the lease is at market rent, then the leased fee value and the fee simple value are equal. However, if the tenant pays more or less than market, the residual owned by the leased fee holder, plus the market value of the tenancy, may be more or less than the fee simple value.
The scope of work is the first step in any appraisal process. Without a strictly defined scope of work, an appraisal's conclusions may not be viable. By defining the scope of work, an appraiser can properly develop a value for a given property for the intended user, and for the intended use of the appraisal. The whole idea of "scope of work" is to provide clear expectations and guidelines for all parties as to what the appraisal report does, and does not, cover; and how much work has gone into it.
2. Investment method. Used for most commercial (and residential) property that is producing future cash flows through the letting of the property. If the current estimated rental value (ERV) and the passing income are known, as well as the market-determined equivalent yield, then the property value can be determined by means of a simple model. Note that this method is really a comparison method, since the main variables are determined in the market. In standard U.S. practice, however, the closely related capitalizing of NOI is confounded with the DCF method under the general classification of the income capitalization approach (see above).
Two things have been artificially sustaining the market, says Chris McCarty, director of the University of Florida Bureau of Economic and Business Research, the Federal Reserve’s infusion of cash to lift the country out of the last recession and the 2018 tax cut. Both actions put a lot of money back into the economy. The Fed is starting to raise interest rates, he says, and the tax cut boost is temporary.  
At other times, a buyer may willingly pay a premium price, above the generally accepted market value, if his subjective valuation of the property (its investment value for him) was higher than the market value. One specific example of this is an owner of a neighboring property who, by combining his own property with the subject property, could obtain economies-of-scale. Similar situations sometimes happen in corporate finance. For example, this can occur when a merger or acquisition happens at a price which is higher than the value represented by the price of the underlying stock. The usual explanation for these types of mergers and acquisitions is that "the sum is greater than its parts", since full ownership of a company provides full control of it. This is something that purchasers will sometimes pay a high price for. This situation can happen in real estate purchases too.

In addition, there are professional appraisal organizations, organized as private non-profit organizations that date to the Great Depression of the 1930s. One of the oldest in the United States is the American Society of Farm Managers and Rural Appraisers (ASFMRA), which was founded in 1929.[28] Others were founded as needed and the opportunity arose in specialized fields, such as the Appraisal Institute (AI) and the American Society of Appraisers (ASA) founded in the 1930s, the International Right of Way Association and the National Association of Realtors which were founded after World War II. These organizations all existed to establish and enforce standards, but their influence waned with increasing government regulation. In March 2007, three of these organizations (ASFMRA, ASA, and AI) announced an agreement in principle to merge. NAIFA (National Association of Independent Fee Appraisers), a charter member of The Appraisal Foundation, helped to write Title XI, the Real Estate Appraisal Reform Amendments. It was founded in 1961.

I just wanted to let you know how helpful Mike Nichols was in helping us through a complicated situation in a real estate transaction where a tax certificate had been sold on the subject property. He went above and beyond the call of duty, patiently explaining the situation separately to all three parties involved. The issue was resolved with his help and his response was excellent.
 I spoke with John about getting an appraisal for the home I was purchasing and even though it was short notice, he was able to fit me in the next week. I gave him my information and told him the last inspector I called had agreed but had to back out when he found out how large the house was, but John said it would be no problem, and figured it would take a couple of days to do the appraisal and get the proper amount of comps. I had no problem with his fee, as I know that large houses can cost even more to inspect and appraise and thought his prices were reasonable-- especially considering how quickly he was going to get it done. Right after our phone conversation he sent me an email and sent the contract, which I signed and emailed back, and gave him my credit card info., which made it very easy to deal with versus writing another check-- which you write so many of in the house purchasing process. He arrived promptly and introduced himself, and was just as pleasant in person as he was on the phone. He did a thorough job of going through the house, and really seemed to know his business very well. He was nice enough to point out some positive aspects about the house we were purchasing, and pointed out many details. He was very knowledgeable about the housing industry and houses in general as well, and after business talk, it was nice he took the time to just chit chat for a bit. After speaking with me on the phone and chatting at the house, he gave me some great information about places he thought I would be interested in visiting, because he figured out pretty quickly I was a nerd who would be into some of the places he mentioned. He was right! Great information and advice! I really enjoyed doing business with John, who I found interesting, knowledgeable, and excellent to work with, and if I ever need another appraisal, he is definitely the one to call! I would highly recommend him to anyone who wants the best service in this business!

The notice shows property owners their just, assessed and taxable values for the prior and current years. It also provides a comparison of the prior year taxes for each taxing authority to the current proposed property taxes.  Exemptions and reductions in value due to assessment caps are provided, along with any non-ad valorem assessments.  Current year taxes are based on property values, tax exemptions and the proposed tax rate that has been set by the taxing authorities.
