In Florida we have a Save Our Homes property tax discount that limits the amount the assessed value can increase each year to 3%. Very long term homeowners may pay significantly less than you will pay because the house will be moved up to "market value" for taxing.
Google the Broward County Tax collector and it may offer a tax estimator on their website. Your Realtor should also be able to give you a fairly good estimate of what your taxes will be.
Hope this helps.
