What is it you're wanting to do exactly?? Sell your current home and buy the new one? Or keep the current one, renting out, and buy a new one? I would figure that out first, then you need to talk to a lender to get pre-approved. If you're wanting to sell your current home, then buy, it can be a tricky process. You should talk to a local REALTOR to discuss what you're trying to do. If the market is super hot, it might be difficult to buy the new home with a contingency of selling your current home.
