Are you in SF?
Keep in mind that TIC mortgage interest rates are higher than single family & condo interest rates because the securities that they generate are less liquid (the bank can't sell the loan to the government). Also, only a few banks write loans for TICs.
You should be able to whip out excel and figure out the single family-equivalent price on the property.
TICs also can have the same management issues as small condo associations. In addition, a sale by someone else in the association may trigger revaluation under prop 13. TIC association bylaws should prevent this from affecting you, but who knows what would happen in a sale forced by bankruptcy, etc.
