What happens? Can you get rid of it or is the house ruined? If mold is on the siding outside of the house does that mean it is on the inside too? Thank you in advance for you answers

Many years ago, I knew a couple who were snowbirds and also my neighbors up North. They puchased a home in FL and when they left for the summer they shut the heating/cooling system totally down. The following fall they returned to a home that wreaked of mold smells. Mold occurs in rugs, bedding, under sinks, bathrooms, anywhere favorable conditions exist. Needless to say the odor of mold, once established is nearly impossible to erase and their winter home never was free of the odor and rendered the home nearly impossible to sell.
Today's technology, I'm sure has found ways to alleviate it but nothing can beat the method of never letting it exist. If you leave your home for extended periods of time, a DEhumidistat is the way to go and will pay for itself in the first summer. It's also a very good idea to have a neighbor or friend or hire someone to check your home inside twice a month. Storms and/or malfunctions can cause your system to fail.
The mold that appears first on the North side of homes is a seperate issue and should be not allowed to exist for extended periods of time. Many reliable "power wash" company's can remove the mold stains and also apply preventive cleaning agents.
