4 plex MLS vs 5 plex Tax Roll

[Ranjit Sandhu]

Showing this property to one of my client tomorrow. MLS shows 4 plex but tax roll shows 5 units, seems like 5th unit is burnt. Will it be considered commercial property then as these are 5 units not 4? MLS states 4-unit apartment complex spread across four different structures vs tax shows building 1 of 5, 2 of 5 etc...So the question is how will buyers mortgage work? they residential or commercial, looks like commercial, right?

Any feedback will be appreciated.
