With today requirements for accounting, somebody with economics background could tell what would be wrong with following solution?:

If you house owned by commercial entity - taxes are payed from full value, but the valuation to any collateral/derivative goes by something like (0.75x)^l, where l how many levels deep (counting ownership levels). For example it house is in some sort collateral/derivate/indirect ownership mix with 4 levels deep, it can only valuated as 0.31x value (you can only account as it is worth 1/3). In my mind it should reduce attractiveness for speculative buying.
