Should you sell now or wait for more appreciation is a question a lot of people are asking themselves. It all depends what your needs are. As the price on your home rises, so does the price of the home you might be buying so in the long run it doesn't really matter. If you are upside down on your home, then you might want to wait until the price goes up high enough for you to sell without a loss. If you have equity and are looking to buy another home, then try to get as much money for your home as possible by marketing it properly and then try to negotiate on the purchase and it will be a win win situation. There is no telling what the interest rates will be a year from now, so if you will need a loan to buy another home, you might be able to qualify for a higher loan today than you will a year from now depending on how much they rise. It is too difficult to time the market and know when the right time is to buy or sell. Right now it's a seller's market in the price point of $500,000 and below and especially under $300,000 since the inventory is so low. Therefore you will most likely get a very good price for your home. A year from now if the inventory increases, then the demand for an individual home goes down and since there is more competition, you might not get as much as you would when there were less homes to choose from.
So as you can see, it all depends on your situation and what your goals are.
Good luck in whatever you decide to do.
