PREPARING YOUR HOUSE TO SELL FAST LOS ANGELES! Part of selling your house fast for the most money is going to come from the work and efforts you put in leading up to listing it for sale. Give yourself a full 2 weeks to prepare (sometimes you'll need more) because there are a lot of things you want to do in advance to make your home sell fast! Consult with a top local real estate agent to ensure that you are preparing your home for sale the right way. If your home was once an expired listing it will likely sell the next time around if you prepare it the right way. Almost 90% of a home sale happens before you list the property for sale, the rest involves negotiations and paperwork, the easy part.
