selling a house is not just based on water views (some buyers might not value it as much as you would or may have different value to them depending on if it is ocean water view, pond/lake water view, which one do you have?). Putting the house on MLS with some standard pictures is not enough (I've seen some pics that should have never been used), specially if it is a house on the higher end, to sell it.
You need a stronger strategy to sell your house and your agent should be able to walk you through this. If you are doing fsbo (for sale by owner) that just listed on mls you may be missing out on a much larger pool of buyers. Also, make sure your are not overpriced as this will do more damage than good. You will also need to make sure you dedicate enough time to selling your house and that it is easily available for showings. Check your listing, your pics and description again and see if you would change anything. As I mentioned there are lots of details and strategies involved in selling a house. If I can be of assistance let me know. Best of luck
