Yup, thinking out the box would mean that some re-deeding would need to be done to create a full-ownership unit. At the resort in question there always has been some full-ownership, some 1/4 shares, some 1/8 shares, and some intervals, so sharing amenities is not an issue. It would be easier to combine 1/4 and 1/8 shares into full ownership than it would be to combine intervals, but doing so has increased the value of all ownerships.
If you will read the final report on Apple Valley that Brian attached above, it is the largest lawsuit ever filed in the State of Ohio, based on the number of defendants. 1581 interests had to be "partitioned" into a marketable deed, or deeds, for all the units, the clubhouse, the swimming pool, the resident manager's condo, and some vacant properties.
By comparison, "partitioning" 50, or 8, or 4 interests into 1 would be easy peasy.
At both resorts I'm sure there have been a lot of
interesting discussions the last 25 years, with the best ones being the ones that came up with these plans to resolve their problems.
As I've mentioned before, in order for these things to succeed, there has to be a real market value.
That might be a bit tricky if the original deeds were Fixed Unit or, at least, unit specific. Might be easier to do if all deeds were floating units. I'm sure it was also an interesting board discussion on what rights the full-share owner had to amenities?
