Talk with a lender who will look at your whole financial picture and help explain your options. No one could give you an intelligent answer without more info about your finances.
Concerning your house in WA: Instead of selling, maybe you could rent it out. If you do need to sell it, you'll have to get the opinion of a good local real estate agent, but usually if your home is being properly marketed and is not selling, it because it is priced too high.
By decreasing the price of your Washington home you will increase the chances of selling it. This may be able to be off set by being able to purchase in Vegas at a cost savings price.
Our recommendation is to study both markets closely. What you lose in Washington may be able to be made up in Vegas. It may not be as distant as you think.
