Was wondering if other people went down this avenue

The people the seller should have this discussion with is the title company and or legal counsel.  

Unless maybe that is counting people's $1M residences. or average price of homes in Austrialis is probably 1 mil or more. at least in the big cities

I've seen a lot of people mentioning reading books and soaking up knowledge to start.

Go to local meetups, search these forums for people that have mentioned that they do private lending and attend other RE events.

I shows my what dates people are searching for this year and last year.

A well connected agent can also tap into their network.. for instance, probate attorneys might know of people seeking short-term solutions.

For context, this would be for a property I already own.I understand this may be a bit unconventional and people will likely recommend I get a proper quote and have the contractor do a full walkthrough.

For most people a house hack is a great start. 

people will sue for anything these days.
