If I were in the situation I would hopefully have used a Deposit to Hold agreement and I would keep the deposit, cut ties with the already not-understanding tenant, and search for someone who exhibits the qualities I value in a tenant (namely their Mindset).You have either a crystal clear case to do that, or a fairly clear case (depending on whether or not you used a deposit to hold agreement). 

This stuff might come back to get you as an exhibit in a trial if your tenant wants to sue you for renting an unliveable unit. 

I would judge based on the number of questions / uncertainties you seem to exhibit about the situation - that you are unclear about the Landlord Tenant Laws where this property is located. 

I'm going to try to freelance and make some money while traveling to make this as sustainable as possible for a long period of time (probably to Chiang Mai or Australia first).

We are property investors from Australia - we can't qualify for a loan since we have no credit history, so the 1st property will be all cash. 

The market exhibits appreciation in property values, creating equity and potential profits upon resale.

Everyone knows about the hackers who will just send fake wiring instructions, but here it looks like the newest fraud model is actually just outright creating a fake title agency and targeting wholesalers , who frequently have no idea what they are doing (exhibit A here) and far less likely to see red flags like a fake title agent from a bogus company apparently offering to help find a buyer.

Best country in the world mateI still call Australia "home" tho hehe

How willing would you be to lend money to a complete stranger that exhibits signs of being over-leveraged but says "I'm good for the money, trust me"?

Other lien-owners exist for this property (one from PA and another from Australia?).
