If you just need a signature from a couple of people this may work for you. https://app.hellosign.com/info/pricing?

If you're looking for people to network and discuss real estate investing with in Korea, we have a meetup that started with people who were active on BiggerPockets.There's a link in my signature for more info.I invested from out of country last year in Jacksonville.

If those options don't work, maybe consider a HELOC, signature loan, or crowdfunding request as other possible ways to gather necessary cash for the DP.

If you decide to send back the $150 have your checks printed with a release right below the signature line on the back.

If you post the area of the property you are looking at, a LO in that market might have a keyword alert set up, flagging this thread so they can answer, and poof look at that they just might have their contact info below their post in their signature block.

I would send it via certified mail, signature required, return receipt.
