Can a loan company seek a judgement before the foreclosure is complete?

Yes.

Nevada has a "one action rule" which requires them in most cases to go after the collateral before seeking other remedies. What that means in your case is that if they attempt to get a judgment on a debt secured by property before going after the property, you can usually make a motion to stay the proceedings until the property is dealt with (i.e. until the foreclosure process is completed). You also have the option of allowing them to go forward, and if they get a judgment before completing a foreclosure sale, then the property becomes unencumbered by the debt. In most cases that is unhelpful to you, but there are some circumstances where it can be beneficial.

In most states, a formal foreclosure process must be completed prior to any loan company having rights to a foreclosure judgment. You should seek the advice of an experienced attorney who can review the documents and proceedings in your particular case to help you evaluate your rights.

Yes on both counts. Although you don't see it very often, the bank can sue you on the note before they foreclose. What I understand from creditors' lawyers, this tactic prevents them from having to worry about the forgiveness of the deficiency provisions that can occur when the bank credit bids at the foreclosure sale (although I don't agree it is a complete defense to same). You see this action mostly in commercial loans where the creditors' lawyers are more active in collection.
