A track record usually shows only the hits. We also say what we turned down, because that reveals more about a buying profile than any single deal.
Most properties we review, we do not buy. That is not a flaw, that is the work. A rejection with reasons is worth more to a seller than an offer that gets withdrawn later.
A real example: an eight-unit building of the right size in a decent location. Rejected. Not because of the property. Because of the maths.
