I don't think a property in a water logged area could be suitable for the LandDAO team, not just for them but for the buyers that would be interested to be a land parcel. A water logged area may requires huge amounts of sand to refill the area before it will be suitable for any building construction.
If you want to sell a land or you have a land you want the team contributors to review, it must be a good and cheap land that will be suitable for whether building or recreational purposes.
I've a different theory on this, I think that if a quarter plot of land will stand for a single token then half will stand for two, having a full plot, half and a quarter all standing for individual price of NFT will be the same as LandDAO having multiple token rather than just one but I do like the idea that you've brought in, a plot of land might be too big depending on who wants to buy it and will be too expensive too, but if they switch to tokenizing a quarter plot instead of a full plot, in increases the chances of the common man being able to purchase their token while still keeping things the same for large scale buyers, if an investors wants to buy a full plot of land then they should just buy 4 tokens instead of 1.
