Is this something you want to sell or something you want to buy? Since you are identified as a home seller, I will assume the former. There are many different house values.
The market value of your home is what the market is willing to pay for it and that will be affected by the number of competing properties. If there are many similar properties, the market value of your home tends to go down because customers have many choices. The replacement value of your home is what it would cost you to rebuild the house. Unfortunately, there are properties right now whose replacement value is much higher that their market value. The appraised valkue of your home is what an appraiser would tell you your house is worth after looking at comparables, market conditions, condition of house,... The assessed value of your home is what the tax people will use to determine your property taxes.
