At the Hold Short line for runway XX; I heard another aircraft announce it was on the RNAV for runway XX and was planning to do a low approach. I asked the aircraft its location and I thought I heard him say 7 miles. I took the runway and announced I was departing runway XX. Within 5-10 seconds the pilot of the other aircraft announced he was breaking off and that I was in his way. He then immediately flew overhead and to the right of my aircraft approximately 300 feet above. I realized instead of saying 7 miles; he must have said 1.7 or 2.7 or something. I don't know the aircraft type and didn't catch his tail number; but it was a twin.
C172 pilot reported a conflict developed after taking the runway in front of an arriving aircraft.
