Hello Scott and thanks for your post.
Your very best answers are likely to come from a qualified Realtor in the area. Because geographic regions are very specific, obtaining accurate, good pricing and comparative sales information needs to come directly from an agent. We don't usually post that information here on Trulia, although you can get comparative sales information from Trulia--look up the address of the home you're interested in purchasing and click on the "sales" tabs to obtain comparative sales information.
Aside from comparative sales data, however, please know that comparing Condo-hotels or "time shares" with a regular condominium is truly like comparing apples and oranges--they're both fruit, but they're very different. Unless the circumstances are drastically different than what is conventionally found in a condo-hotel, both the condo-hotel and the regular condominium are, in fact, condominiums, but the owner of a condo-hotel or "timeshare" is buying what is legally called a "community apartment" unit in which a "community" of owners purchases one home. Thus, as the owner of a condo-hotel, most owners are not allowed to live all year in the condo-unit, but may only live for a brief period (anywhere between 1-2 weeks per year) in the condominium. Outside of the two weeks, the condo is used by the other owners of the unit. A regular condominium, however, is the home buyer's residence and can be used all year by the home owner.
Financing for condo-hotels is also slightly different since the owner is actually only a "share" of use of the home, the pool of available mortgage money begins to dwindle. To combat this, however, the developers of most condo-hotels have financing packages already available for the buyer.
Again, check with a local agent in your area for the best and most accurate information about home sales, condo-hotels and the nature of real estate in Miami Beach! Good luck!
