This is so true. Not only do they typically not know anything more about nay given home that you, the buyer, do. If they are on the selling side they will also outright lie about home features. I experienced this so many times on houses I visited and even on the house I ultimately purchased.
You just have you shrug your shoulders and fix whatever they misrepresented.
In my state you should file a complaint against that agent with the department/office that oversees real estate licensing. And you might be eligible to be compensated for the agents misrepresentations if you can prove them.
I'd love to. Some of the things seem difficult to prove. Such as
> Welcome Home!!! Take a seat on the PORCH SWING on your COVERED DECK and enjoy the Fall Season! Come inside this cozy home and view it's OPEN FLOOR PLAN [calling this open floor plan is a big stretch], Original HARDWOOD Floors [and they are destroyed as a result. Water damage. literally cut through to put in a furnace in the basement in one place. Covered by a carpet in the living room and destroyed as a result] and FRESH Neutral Paint. Two bedrooms and a LARGE full bath [probably as small as it gets while still being a full bath] on the Main Floor with a SUNNY eat-in Kitchen and Conveniently located MUDROOM, additional bedroom/office in the basement [not legally a bedroom]. This home features Updated ELECTRICAL [in some places sure. Half the house is still crappy old cloth wrapped wire], Updated PLUMBING throughout, Living Room is WIRED for SURROUND SOUND, [broken] SPRINKLER SYSTEM and NEW Roof with a LIFETIME transferrable Warranty! Detached Garage has HEAT & A/C, Wired for Cable and LAN line [a CAT5 cable that terminates in the floor and is not accessible to be hooked up to anything because it's in the floor!], has Electric [electricity to the building no where near code because it is fed from two sources] and a HUGE Attic space to Provide LOTS of EXTRA STORAGE. This home has a Private COVERED PATIO in the back where you can relax and enjoy YOUR NEW HOME!
There was more in the listing than this but that's just the basic bio.
