What stands out

Reading these figures against all 7(a) borrowers:

  • Loans here run larger than average. The median of $200,000 is 33% above the $150,000 national median. Expect lenders in this market to be geared toward bigger deals, and expect a small request to get less attention.
  • Startup share is about average, at 29% against 34% nationally.
  • Lending here is fragmented. The top three lenders made only 24% of these loans between them, so no single institution owns this market. That is good news: it means shopping genuinely pays.

Before you apply

  1. Check coverage first. Run the payment through the affordability calculator at 1.25x.
  2. Shortlist from the lender table, favouring ones whose median loan here is close to what you need.
  3. Assemble the documents — see the checklist.
  4. If you are buying rather than starting, read business acquisition loans first; the injection rules and diligence are different.
