I have a tenant that has gone to jail and realistically may end up in prison.Her boyfriend brought me a notarized “Power of Attorney “  stating he wanted to enter her apartment to get some items out.From my understanding a POA is usually either MEDICALLY OR FINANCIALLY based.Am I legally bound to let him enter?

I am a notary but I've never looked into the LSA route because as was mentioned most banks will notarize docs for free and if you ask most title companies will send the borrower the closing package including instructions to the notary via email. 

Get it notarized and record it.

Even if it were separate property, H's estate owes reimbursement to the marital/community estate for part of the CP spent on SP (payments on loan, taxes, insurance, maintenance, etc) over the years because CP earnings paid for these itemsSub-2 won't work because dead H cannot sign/notarize docs required.Not my site, but useful chart: http://blairwells.com/helpful-... 

You could get a notarized document signed with a couple hours notice.

My thoughts are, we sign the purchase contract, get a purchaser's affidavit and special warranty deed notarized, and then I can record with the local county. 

I have access to my father for him to personally sign documents and get them notarized but I live very far away and this is reserved for once or twice a year.

@Jeffrey Wannberg Not sure about OR but in WA any lease more than 12 months has to be notarized to be valid.

If not, are they able to?  

You can get the POA notarized.
