6.5 foot Ceilings, is this a concern

[James Bradin]

I am looking at making an offer on my second investment property.  It is a 1920's built unique 2/1 upstairs, 1/1 downstairs, recently renovated, and in a good neighborhood.  It just got back on the market after the deal fell through.  The previous buyer backed out because the downstairs unit has ceilings that are "about 6 and a half feet high".  I have yet to see it in person, but other than this I am very interested in the property.

The property has tenants in place already, and both units were rented out in 3 days (according to the selling agent).  Should this be a concern?  Has anyone dealt with low ceilings (or something similar), that made their property harder to rent?
