There are numerous reasons where you might need to make a quick sale and when putting your home on the market you would have to be extremely lucky to get that. Many times the property fails to sell after being on the market for many months even if you drastically reduce the asking price. The other disadvantage of course is the cost of trying to sell your home such as estate agent and solicitors fees. If you want to sell in just a couple of weeks then you could sell your home to a company that offers quick sales and have no fees to pay.

They would allow you to sell home for cash which means that you would be able to get on with your life with money in the bank. This can be an attractive proposition if you have been left property in inheritance. You could sell with no outlay and divide the proceeds from the sale between siblings if needed.
You might want to take this option of selling if you are going through a divorce or if you are emigrating and want to leave for your new life with nothing to drag you back home
