Call a Realtor or several in your area and ask your questions. You will pay Realtor fees when you sell but also don't forget title insurance for the buyer, possible state and local taxes on the sale, Most Realtors can give you an Approximate Proceeds estimate that will list all the seller costs so that you will have a good idea what you will have available. Also ask for buyer closing costs, however, so that you will not misjudge what price home you can purchase. Most home prices have been falling in the past several years, so it is a good time to purchase if you have the profit from the sale of your current home and additional savings. Please be careful that you have additional savings that you will leave in savings, however, for emergencies. It is never a good idea to have every penny wrapped up in real estate or any other investment for that matter. Generally financial advisors suggest from 6 to 12 months living expenses in savings whenever possible. Good luck to you.
