While homes are going up for large prices and selling for equally high amounts, not every home will sell like this and you cannot expect that your home will sell for a really high amount, you should go into the market with realist expectations.
While it is easier to get your house ready to sell for the summer time, have the windows open and have bright sunny days to make your home inviting. Selling your house can be an all year round event if you have trouble selling, how ever homes can still be sold in the winter time.
People are often afraid that their home will sell too low, however you must expect that your expectations might not be meet. The price of your home is really set at what people are prepared to pay for it. While also you need to remain realistic and not think that your house will just go for the price you would like to have it sold at.
While it may seem scary the legal side of things in housing sales are pretty straight forward, yes it is legally binding but you can usually trust your legal representative to do the right thing. It is important to ask for advise and have all your questions answered and read through every document before you sign.
