If you have inherited property and you do not want to live in it or you have to sell it so the proceeds could be split with members of the family then being able to sell quickly would be a great advantage. However if you put the property on the market it could remain there for some time and you would have to pay out fees for such as solicitors and the estate agent.

If you need to sell home quickly then you could consider selling to a company that would offer you cash for your home and would allow the sale to go through in as short a time as possible.

You could also choose to sell your home this way if you need to leave your property due to having to move half way around the world due to another job.
You would be able to sell for cash and use the proceeds, if there are any after paying off the mortgage, towards your new home.
You could also sell property quickly if you are going through a divorce and you need to sell your home in order to be able to split the sale proceeds with your ex partner. Again the sale would not come with cost and you would know in 24 hours how much the company could pay you for your home.
