  "description": "When an associate buys into practice ownership, the purchase price is a percentage of practice value, and the payment structure usually spreads that price over a note with interest rather than requiring cash upfront. This calculator takes the practice's estimated value, the ownership percentage being sold, and standard note terms to produce the buy-in price and the monthly payment, then compares that payment against the expected increase in take-home from an owner's distribution share so you can judge whether the deal pays for itself from practice cash flow.",
  "formula": "Buy-in price = practice value × ownership %; monthly payment via standard amortization at the given rate and term.",

  "faq": [
    {
      "q": "What ownership percentage do most first buy-ins start at?",
      "a": "20-30% is common for a first tranche, with an option or expectation to buy additional shares over time as the associate becomes comfortable with the debt load and the practice's performance validates the original valuation."
    },
    {
      "q": "Should the buy-in payment be fully offset by distributions?",
      "a": "Ideally yes, or close to it — a well-structured deal lets the new owner's share of distributed profit cover most or all of the note payment so the associate isn't taking a pay cut to become a partner. If net cash flow is meaningfully negative, the price, rate, or term needs adjustment."
    },
    {
      "q": "Is seller financing typical, or does the associate get a bank loan?",
      "a": "Both happen. Seller notes are common for minority stakes because banks are often reluctant to lend against a non-controlling interest. Full buyouts of a retiring owner's remaining stake are more likely to use a practice-acquisition lender such as a bank with a veterinary lending division."
