Every market will vary, but in general if interior & exterior units are identical,
interior condition & upgrades will weigh-in toward the value/worth of each unit.

Sergio,

With everything equal between the units in the complex the units should be priced in the same price range. An end unit may increase its desirability but does not necessarily increase its value. There are other factor to consider with overall condition being a primary factor.

Thus, an interior unit in pristine condition may bring much more than an end unit of lesser quality.

It is difficult to generalize when doing so without all necessary factors.

Assuming all units are in the same basic condition, then the answer is yes, for 2 main reasons:

1) The end unit costs more to build and/or replace because it has 3 exterior walls. Units that are not end units only have 2 exterior walls. Exterior walls are much more costly than walls between adjoining units (particularly if they are constructed with brick or stone exteriors).

2) Re-sale appeal is typically higher on end units because only one wall is shared with neighbors, so end units offer more privacy, less noise, less exposure to threat of fire or other damage resulting from neighbors' negligence, and more control over things like exposure to possible pest infestation, etc.

Hope this helps!
