The title question is a an open ended question. There are multiple ways to not sell a home.
But we do not live in an ideal world.
While showing homes not long ago a prospective buyer asked me how much value a pool would add when selling a home. My response was simply "not as much as you will pay for the pool. Install a pool if you're going to use it!"
Determining how much your home will sell for is a function of multiple issues and characteristics. Some of those include...
- How old is your home?
- What is the condition of your home?
- Where is your home located?
- What are the competing properties?
- Has there been any major updating?
- What about any major systems issues (roof, AC, electrical and plumbing)?
- What are the current market conditions?
- Who are your potential buyers?
- And a few more depending on the property.
Ultimately, the market will determine the real price.
If one hires a knowledgeable local agent and follows their advice as well as cooperates with reasonable showing requests...there is no reason for failure.
