What are some of the most affordable beach cities to live in Florida?

I have been thinking about moving to Florida for a while now and I really want to live near the beach. I now there are a lot of beach cities in FL that are very expensive but I was wondering if there were any beach cities that are on the cheaper side that have more affordable houses. I am not looking for something right on the water but close by and reasonably priced.

Where can I find Florida sinkhole information?

I am thinking about buying a new home in Florida and have already found a few potential properties that I am very interested in. However, I have heard a lot of about sinkholes in Florida and I was hoping to find out if the houses I am looking at are close to any current sink holes or if they are in areas that have an abundance of sinkholes.

How do I know if my house is in a flood zone?

I am currently looking to buy a new home in Florida and I am very concerned about the house being in a flood zone. Where can I find reliable information on Florida flood zones and more importantly search flood zones by address so I can see if the particular houses I am interested in are in a flood zone or not. Thanks in advance!
