Good question Lela, and there are a few ways to look at this:
1. Yes you can come back and attempt again to offer a price the seller will take.
2. It may be sold when you are ready.
3. You need to get with a good Realtor who can help you and work for you!
If you need any further help or have any questions and you don't want to post on Trulia feel free to email me.
