Idaho Preliminary Notice FAQs

First, filing a lien under the circumstances you present is problematic. There are strict deadlines for noticing intent and recording your lien. Sounds to me like this is an afterthought and not within 4 months of your last date of work, but perhaps I'm wrong there. In any event, if you're seeking items from two years ago, I doubt that would go well for you under a mechanic's lien theory of recovery.

Second, it doesn't sound like there was much of an arrangement between you and the owner, this was something you were doing to improve the residence you were living in. 

Third, if you're broke, what good is the mechanic's lien anyway? Even if it were valid, you'd still need to take action on it to pursue it. If they've just refi'd, I imagine the property is encumbered to a not-insignificant extent. The loan already closed, so presumably they aren't going to refi again or sell very soon. If you don't have the money to pursue a wrongful eviction, foreclosure likely isn't within your current financial ability to pursue. If you aren't going to foreclose, then you still have other claims and remedies, but I'd think you'd handle most of those claims and damages within a wrongful eviction case, should you ever have the means to pursue that case.  

Most likely your best course of action at this point would be a demand letter and potentially a breach of contract action against the GC who has not paid you. If there is a payment bond on the project your may still have time to make a claim against this bond. But otherwise, because you did not send preliminary notice, you would not have lien rights.
