An HOA Resale Certificate is required when selling a property that has mandatory dues or assessments paid to an HOA. But how do you get an HOA Resale Certificate and what does it do? A resale certificate is actually a set of documents prepared by the HOA or the HOA’s management company. The HOA Resale Certificate also discloses any lawsuits they are involved with and other information. As stated in the contract, after receiving the HOA documents and resale certificate, the buyer has a specified number of days to terminate the contract if they don’t like what the resale certificate or other documents reveal.
