At the surface it seems there should be a market solution for this. One approach might be to do something clever with mortages and property rights. Basically keep trying to keep the current mechanics of borrowing and just shifting around the parties involved so that the all the interest gets collected as LVT. Might even let the central bank handle both collection and dividends of it all. Another option might be to create economic incentives for some party to get the assessment right. Like insurance companies and banks loose either customers or revenue when getting it wrong. Perhaps can play with some margin for speculation such that lender and borrower get to share some profit. Or just make lenders outbid each other on who can extract most rent for the property. I guess one concern here is to make sure the commons have a representation, so that not all land get appropriated to private use
