Homes will deteriorate if they are not used. Foreclosures sit vacant for months or years before they make it through the bank’s foreclosure process. This is extremely hard on home’s mechanical systems. If the former owner knew they were going into foreclosure it is likely they had not been conducting routine maintenance. When homes do not have air circulation in Florida they mold and decay causing additional problems for the interior and the mechanical elements. Most real estate contracts in Florida are “As Is”. You are buying them as is without recourse. Know what you are buying in advance so you can negotiate the best deal possible.
