Always practice due diligence when investing in tax sale properties. If you have time, visit the property and inspect it carefully because photos can only say so much. You would be surprised at the number of times investors have won at auctions, only to find out personally that the property does not measure up to their expectations.
With due diligence, you must also get a copy of the title and check for liens, at the registry of deeds in the area where the tax sale property is situated. Always note that a tax lien is a legal claim against a property. Also, remember that you would be responsible for the lien as foreclosed properties are sold on an “as is where is” basis.
