Doesn’t Fee Simple assume a property is vacant or owner-occupied?
Fee simple doesn't make any assumptions. It is the owner's legal status of the property rights.
Therefore, a leased building cannot be Fee Simple ownership.
Correct. ... However, if the leases are very short, commonly one year or less in commercial appraisals, or the leases can be easily revoked at the landlord's choosing (i.e., the owner can get to full unencumbered use), then it can be considered a fee simple ownership.
Since a lease encumbers a property - Fee Simple cannot portray a 20-tenant retail building that is leased at market. Furthermore, a 20-space retail building that is vacant is worth much less than if filled with tenants.
This example is a question of modeling of cash flows as it pertains to a particular property type at its highest & best use. The value of a fully
occupied 20 bay building may very well (depending on the location, quality, etc., etc.) be worth more than an
unoccupied building.
Starbucks could occupy a building month-to-month or say 6 months giving the owner FS -- and neither party desires to change the occupancy.
Starbucks could occupy the same building but with a 50 year lease tying up the property rights. The values might be the same or different depending on the market conditions and market area.
We get into issues of H&BU and the reversion of the property. Maybe the vacant 20 bay crappy retail is
more valuable because you can now build a skyscraper or assemble into a regional mall. Pity the poor landlord across the street with an identical 20 bay crappy retail center with 20 tenants on very long-term leases. The FS, here, clearly is far more valuable than the LF.
Other property types like churches or smaller buildings may be different. Property types could be occupied reasonably quickly might not suffer such discounting. Leased fee
at market rents does not necessarily equal fee simple as you illustrate. With simpler properties leased fee
at market rents can be
equivalent to the
economic rents that would be paid for fee simple property rights. ("Economic rent" is the factor costs or opportunity cost that would be paid for a resource.) Sometimes clients want the hypothetical fee simple value because leased properties can sometimes be far higher than the fee simple rents.
Blockbuster which had a semi-monopoly on the VHS, um DVD, in the movie market, were paying above market rents, at least in my area when compared to what a weaker brand or non-national credit tenant would pay. This put banks (and the investors who paid above-market prices for that leased property) at risk should it go dark.
