Real estate transaction varies by state. I had one done last month for Louisiana, required 2 hard copies POA. Lawyer E-mailed POA, I printed 2 copies. POA notarized by the ACS with 2 witness as required by Louisiana. Also ACS website stated you and 2 witness need appointment. Fedex to USA. Some states may have online options now. Other docs for contract and misc docs was able to sign online. Also POA for Louisiana required both copies have notary stamp so pay for 2.
