I bought a sdo platinum float weeks 1-52 2 bedroom lockoff on resale, is there a way for me to know how many staroptions it is worth if i retro it by looking at the deed? Ex, if the deeded week is between 1-21 or 50-52 would it be worth 148k if retroed and if is between 22-27 or 36-49 then it would be worth 81k if retroed?
