Every market is different. What may be selling or not selling in one area, may sell in another area.
The 1st thing you need to do is have a local Realtor give you a market analysis. They will be able to explain local market conditions, what condos are selling for in your area and give you an idea about average market time. Ask the agent to give you a Seller's Net Sheet which will show you what it costs to sell....title, attorney, transfer stamps, tax proration, etc..
If you feel comfortable with what your projected sales price is along with selling costs & market time, speak to a lender to see what you can afford to buy. If you are ready to move on after that, get your home on the market, decide what areas you are considering buying in along with the amenities and price range and have your agent send you what is available.
The Realtor you work with should be able to help guide you through all the steps.
I hope this helps!
