- Most real-world deals combine more than one of these — for example, a bank loan for part of the price and a vendor take-back for the balance.

Being invited to buy into a law firm, medical practice, dental office, or accounting firm is a milestone — and then comes the harder question: where does the money come from? Most incoming partners don't have the full buy-in amount sitting in savings, and financing a partner buy-in at a professional practice works differently than financing a house or even a typical small business.
Professional practices carry their own wrinkles: ownership is often restricted to licensed members of the profession, the "assets" being bought into are frequently intangible (goodwill, an existing client or patient base, a share of future billings), and the valuation methodology is usually set by an existing partnership or shareholders' agreement rather than negotiated from scratch.
This article looks at how these buy-ins are typically financed, what a lender or the existing partners will want to see, and where a lawyer's review protects you before you sign anything.
How Practice Buy-Ins Are Usually Financed
| Financing source | How it typically works | What to watch for |
|---|---|---|
| Bank or credit union loan | A term loan secured against the incoming partner's personal assets and/or a pledge of the acquired shares or interest | Lenders want to see the practice's financials and your personal net worth, not just the practice's reputation |
| Vendor take-back from the departing partner | The seller finances part of the buy-in price directly and is repaid over time out of future earnings | Terms (rate, repayment schedule, security) are fully negotiable — there is no standard or "typical" rate |
| Gradual/staged buy-in funded from earnings | Some or all of the price is paid down over several years from the incoming partner's own share of profits | Reduces upfront borrowing but usually means a longer runway before you're a full equity partner |
| Personal savings, RRSP withdrawal, or family loan | Self-funding avoids third-party approval but concentrates personal risk | A family loan should still be documented in writing, ideally with independent legal advice for both sides |
Most real-world deals combine more than one of these — for example, a bank loan for part of the price and a vendor take-back for the balance.
What Lenders and Existing Partners Will Want to See
- The practice's financial statements, typically for several years, to support the valuation being asked.
- A copy of the partnership, shareholders', or unanimous shareholders' agreement, which usually sets out how the buy-in price is calculated and what governance rights come with your new stake.
- Your personal financial statement — assets, liabilities, and income — if a bank loan is involved.
- Confirmation of your professional licensing status, since many practices can only admit equity owners who are licensed in the relevant profession.
- A buy-in or subscription agreement specific to this transaction, separate from (but consistent with) the practice's governing agreement.
Red Flags to Watch For Before You Sign
- A valuation with no supporting method. If the practice can't explain how your buy-in price was calculated, ask for the formula or a valuation, not just a number.
- Vague governance promises. "You'll have more say once you're a partner" needs to be specific — voting rights, income allocation, and decision-making authority should all be defined in the buy-in documents, not left as an informal understanding.
- No plan for what happens if financing isn't in place by the target closing date. Build a realistic financing timeline into your negotiations rather than agreeing to a closing date before you know whether a lender will approve you.
- Existing debt or obligations you're not told about upfront. Ask directly whether buying in means inheriting any existing loan guarantees or other practice-level obligations.
Structural Questions to Settle Before You Borrow
- Are you buying shares of a professional corporation, or a partnership interest? The legal mechanics — and the tax and liability consequences — differ, and this affects what a lender will accept as security.
- Is the price fixed by formula, or negotiated? Many practices use a set valuation formula in their governing agreement rather than negotiating a fresh price with each incoming partner.
- What happens if you can't complete the financing? Your buy-in agreement should address what happens if your financing falls through before closing.
- Will you personally guarantee practice-level debt? Buying in sometimes comes with joining existing loan guarantees, not just financing your own purchase price — read the practice's existing debt obligations carefully.
Frequently asked questions
Can I use the practice's own line of credit to fund my buy-in?
Generally no — a buy-in is usually financed personally by the incoming partner, separately from the practice's own operating credit. Mixing the two can create governance and tax complications, and most lenders won't structure it that way regardless.
Does the Lifetime Capital Gains Exemption help the partner who's selling?
It can, but only if the departing partner is an individual selling qualifying shares of a small business corporation — it does not apply to a straight partnership-interest sale, and qualification rules are fact-specific. This is a question for the seller's accountant, not an assumption either side should make going in.
What if the existing partners and I can't agree on the valuation method?
This should be addressed in the practice's governing agreement before any buy-in is negotiated. If the agreement is silent or ambiguous, get it reviewed and clarified — ideally before you're the one trying to negotiate a number under time pressure.
Do I need my own lawyer separate from the practice's lawyer?
Yes. The practice (and often the departing partner) will have their own counsel, and a buy-in agreement, financing terms, and any guarantee you're asked to sign all warrant independent legal advice on your side of the table.
