So Over House Hunting

I am so over the excitement of house hunting! We put an offer in on a house last night (we toured 5!). The lady that owns the house is out of town taking care of a sick relative in Idaho so we gave her extra time to counter offer. We had a verbal counter offer today from her. She is not budging. To top it all off, the relator that is listing the house was not completly honest with our relator. I don't know what the technical word is, but here is what is happening. Someone already has an accepted offer on that same house. But they have some type of clause that they have to sell two houses of their own first before they can "offically" buy the one we put the offer in on. After/If we get an accepted offer from the home owner, the other people have 48 hours to sell those two houses. If they don't sell those two houses, then the house becomes ours. It's all a big mess. It seems that everytime I get my hopes up about a place, I get slammed back down into reality.
