Just about any mobile home park in the U.S. -- including 5-star ELS properties -- can get that review every time they evict a tenant for non-payment. That's how people use the system, and the ease of the internet has empowered every nut job on earth. Do your own due diligence and make your own decisions devoid of input by non-vetted sources that can't even write proper English. "They don't fix nothing" often means "they are evicting me because I won't pay my rent or get rid of the three pibulls in my yard".
In addition, even rough parks can be brought back to life if they have good locations and infrastructure. Every negative in that review can be fixed with pothole repair and a few lease non-renewals.
Bottom line: don't let those type of reviews alter your thinking. Your decision should be based on due diligence and logic, not anonymous posts by idiots.
