Go celebrate! 

Ifthe property is sold without discharge or release of the lien, the subsequent owner must pay the pastdue taxes and obtain a release from the IRS or risk losing the property for non-payment of taxes.As with past due ad valorem taxes, the usual method to obtain a discharge or release of a federal taxlien is to pay the past due taxes unless the statute of limitations applicable to the lien has expired orthe lien is otherwise defective or unenforceable.

If I was a seller I would want the offer first to know someone is serious before releasing that information to someone I don’t know.

I've made great connections, hell I even sold a house to a certain biggerpockets celebrity that was a personal idol of mine and who's books pretty much got me interested in real estate. 

I’m looking for a promissory note, release of note, release of mortgage, mortgage deed or warrantee deed, or any other great templates for securing, and insuring a private lenders money for WA and CA.

That can be mitigated somewhat by defining an "investment period," where the fund is allowed to acquire only until a certain date, after which time any unfunded capital commitments are released and the investors are free to no longer hold their funds aside for future capital calls. 

There are a lot of threads about NWA on here, I recommend doing a search and reading up, here’s one:http://www.biggerpockets.com/forums/312/topics/70990-house-is-not-selling-advise-please    Also they charge a non-refundable down payment before they even ”release” full property info (I believe it’s $5k, and not Ernest money down mind you, just a straight non-refundable down payment).

If you proceed, have the money put in escrow at closing, with appropriate release language for repairs.

@Qi Gao let them go, and try to release the unit.

Those tiny towns if the tenant goes out the second generational tenant does not usually pay as much so some equity from initial down payment when the property was acquired is erased whereas a strong suburban location to urban area the rents might have actually GONE UP in that time for that area and you can re-lease at higher rates.
