Too bad you didn’t research before signing to find that 6 mos is too long to bind yourself to an agent.
OTOH, you might just have a house that defies a ready sale. As you say, it is out of town - which likely limits the pool of potential buyers. Most homes near are bigger or trailers - which suggests that most people looking to move to the area might either have the money and desire for something bigger, or want a cheap doublewide as an entry to the area. You just need to find the one buyer who values your home similarly to how you do. Which could take time - or a lower price.
IMO 2 things a good RE agent can have going for them are networks of potential buyers, and of other agents. In most areas, there seem to be a couple of agents who seem to have a list of folk who they know are looking for a certain type of house, or “pocket listings” of folk who might be willing to sell. And - if an agent has good relationships with their colleagues, they might be able to benefit from those colleagues’ private info. And, if your home is really super, through her network your agent might be able to get a fellow agent to show your home as a potential option to buyers who might be looking for something somewhat different in a different area.
If your agent lacks either/both of those, posting signs and holding open houses is unlikely to do much to move your house.
Folk often say location, location, location. But in many instances, I think price, price, price could be just about as valid. In almost every instance I’ve seen where a home sits on the market, I believe there is a lower price at which it would sell. Unfortunately, many owners have an unrealistic opinion as to what their home is “worth”, or need to get a certain amount from the sale.
Remember, you only need one buyer. It can be frustrating if you aren’t getting showings, and trying to keep your home spotless. We had one house that was on the market for a month, without a single showing. We were going through stress of a contingent offer to purchase another home, which we finally had to pull the plug on. The very next morning, our agent called and asked if they could show it. It was a Sat. a.m., and we were eating breakfast, the kids were watching cartoons, and the place was a mess. We said, “You can show it, but we’re not going anywhere.” You know the punchline - 95% purchase price offer before lunch.
So the moral is - don’t sweat it (easier said than done.) Good luck!
