do I sign it in the current state I'm in get it notarized and mail it off to get signed and notarized in the other state?

It is being signed today by the seller in PA, notarized, and mailed to me in Gaithersburg, MD.BTW I messed it up like 3 times and had to send it to the seller 3 different times.I left the Title Company blank because I don't have one set up yet.Should I contact one near the seller or near me?

Next time record immediately after signing and notarization. 

Make sure you have a signed and notarized copy for your fee, to be paid at close.

Off to bank to sign wires  get all my deeds notarized and escrow ( sell docs) back in fed ex all done by 1pmWholefoods to buy what I am going to cook for dinner..

Notarized, recorded, official, etc. 

Does this get notarized and filed with the state?

We can do it all from here as long as the contract is notarized.  

You can look up the current owner here with the serial numbers:https://www.tdhca.state.tx.us/mh/ownership-locatio...The transfer is relatively easy and requires a couple of notarized documents. 

Is this how it works:  So the seller signed it, it was notarized, then, the title company brought that deed to the County Recorder to record.
