Was the house tied up in probate for circa five years? If so, was it rented during that time?
As @Mike9241 suggested, you really should consult a local tax professional.
If the house was in the estate post-mortem and rented, depreciation would start over (a new 27.5 year recovery period) at the property's fair market value as of the date of death (i.e., that would be the basis for depreciation). In that event, the estate would almost certainly have been required to file a 1041.
