Average Multiple Expansion for Search Acquired Businesses?

Just another n of 1 but my approach would be based on two factors: 1) how much of a discount to market price is the current deal - this would be typical if seller is retiring and selling at below market or a similar situation, 2) if the plan for the company is to substantially increase EBITDA to another threshold of buyer; A sub 500K SDE usually sells for a lower multiple than a >1M SDE and then another step up for multi-million dollar SDE and so on, 3) growth trajectory leading to exit period - multiples will be higher for a business with consistent top line and EBITDA / SDE growth. I don't have specific numbers I use but factor these into my thinking about what an exit multiple could look like in different scenarios.
