My neighbor is buying myhouse. We settled on a price. Pretty simple. Why would I needa lawyer

It is your choice whether to spend a relatively small amount to retain a competent real estate attorney to represent your interests at the beginning of and throughout a real estate transaction, or spend much more money later in litigation costs and litigation attorney's fees in the event of a problem.  We can speculate on the numerous ways this friendly deal can go bad, or you can hire a competent real estate lawyer and protect yourself from the start.   It really is a "pretty simple" decision.   The foregoing is specific to the law and procedure in Florida.  This response does not constitute legal advice as the facts presented are limited and unstated facts will likely impact your particular situation.
