Hi Roy,
Thank you for your comments.
The property is owned by a trust of elders in the family, basically 6 siblings, with one of the siblings who is in charge of all this.
The in-laws tenancy will likely just be verbal, seems that's how everyone wants it. The most that would probably happen is we don't go to a lawyer, we just write out the terms on a piece of paper before hand so that there's no dispute down the line.
The vendor is not considering any other options at this point. He has agreed to hold the property at the price for us for another year or two, hoping that the in-laws will get their finances in order. Obviously, everything is geared positively towards them.
Your second to last paragraph you wrote is why I'm looking at other options. It's so awkward, especially when the banks get involved.
My wife and I will be running a business from the land, a home day-care. But we're doing that either way. And we're growing an orchard, either way. But both options we can't really throw ourselves into without more permanent commitments. So yes, we are expecting to make a bit more off of the land if we buy it.
