My only note again, is that there is no such thing as a PUD. Realtors have been using this word for years and it is incorrect. Anytime you call something a Unit, you automatically define it as a condominium.
Now as to your question, yes, there is usually a small price difference both in terms of listing as well as appraisal between the condo and the lot in a PD or planned development specifically because the owner of the former owns only an airspace envelope while the latter has a deed that specifies ownership of a building plus the lot or land beneath or around the home. Nowadays, however, with such little inventory on the market, and precisely because so many Realtors as well as Buyers are confused about the "PD v. Condo" issues, that price gap between the forms of housing narrows. PDs still command more money, all things being equal regarding the characteristics of the homes, over condos, but the difference is a bit less noticeable these days. Remember buyers set the prices and if buyers are willing to pay the same amount for both forms of ownership, the pricing gap narrows.
Again, Blue, work with an agent who truly understands these types of housing products and who can properly inform you about what you are buying and the obligations of ownership.
