Oncology Practice Down Payment: How Much Do Buyers Need?
The oncology practice down payment is often one of the first questions a physician asks when considering an acquisition. How much cash a buyer needs to bring to closing depends on the loan program, the lender, the size and structure of the deal, and the strength of both the buyer and the practice.
There is no single answer, and this article does not quote specific percentages because requirements vary widely. Instead, it explains what shapes the equity requirement, what sources lenders may accept and why oncology buyers need to think about liquidity beyond the down payment itself. Nothing here is legal, tax or financial advice, every loan is subject to approval and nothing here is a commitment to lend.
What Lenders Mean by Equity Injection
Lenders generally want the buyer to have a meaningful financial stake in the acquisition. This contribution, often called an equity injection, shows commitment and reduces the lender’s risk. It may come from the buyer’s own cash, from certain other sources the lender accepts, or in some cases from a combination that includes seller financing.
The required amount is set by the lender and, for government-backed loans, by program rules. It can vary from one transaction to the next.
Factors That Shape an Oncology Practice Down Payment
Several factors can influence how much equity a lender requires:
- Loan program: SBA-backed and conventional loans apply different standards
- Deal size: larger transactions may receive more scrutiny
- Practice cash flow: stronger, well-documented earnings may support more financing
- Buyer experience: prior ownership or leadership may reduce perceived risk
- Credit history: personal credit and existing obligations matter
- Goodwill versus hard assets: deals heavy in goodwill may be viewed differently than those with substantial tangible assets
- Transition risk: how dependent the practice is on the selling physician
In oncology, lenders may also consider drug margin trends and Medicare exposure when judging how much risk the deal carries.
SBA 7(a) and Conventional Loans
SBA 7(a) loans are often used for practice acquisitions and have program rules regarding equity injection. The specific requirement depends on the business, the buyer, use of proceeds, program rules and lender review, and those rules can change over time.
Conventional practice loans follow each lender’s own underwriting. Some lenders may finance a larger share of the price for highly qualified buyers and strong practices, while others may require more equity.
Can Seller Financing Help?
A seller note can reduce the amount of cash a buyer brings to closing. However, lenders and programs may limit how much seller financing counts toward the buyer’s equity and may require the seller note to be placed on standby. Seller notes are typically subordinate to the senior lender. Earnouts may also be restricted. Any seller financing should be structured with counsel and reviewed with the lender early.
Acceptable Sources of Funds
Lenders typically want to verify where down payment funds come from. Sources that may be considered include:
- Personal savings and investment accounts
- Gifts from family, with proper documentation and lender approval
- Proceeds from the sale of other assets
- Certain retirement fund structures, which should be reviewed with tax advisors
- Seller financing, subject to program and lender limits
Borrowed funds used as a down payment may not be acceptable or may be treated differently, so buyers should discuss sources with their lender before committing.
Liquidity Beyond the Down Payment
This is where oncology differs from many specialties. A buyer who puts every available dollar into the down payment may have nothing left to fund drug inventory, payroll and receivables while payer enrollments are updated after closing.
Lenders often look at post-closing liquidity in addition to the down payment. Our guide to oncology buy-and-bill cash flow explains why drug purchasing creates significant working capital needs. Many buyers include working capital in the acquisition financing or arrange a separate line of credit.
Estimating Your Total Cash Need
When planning an acquisition, buyers may want to account for:
- The equity injection required by the lender
- Closing costs, legal fees and due diligence expenses
- Drug inventory purchased at closing, if not included in the price
- Working capital reserves for the transition
- Personal reserves for living expenses

Buy-Ins, Buyouts and Real Estate
Equity expectations can differ by transaction type. A physician buying a partial interest in an established group may face different requirements than one buying an entire practice, because the existing partners and the practice’s track record remain in place. Partner buyouts, where remaining physicians purchase a retiring partner’s share, raise their own questions about who contributes equity. If the purchase also includes the building, real estate financing may carry separate equity requirements. Discussing each component with a lender early can help a buyer understand the full picture.
Strengthening Your Position
Buyers who want to reduce their equity requirement or improve their terms may consider building savings early, paying down personal debt, gaining management experience, choosing a practice with stable cash flow and preparing a thorough business plan. Our article on oncology practice loan requirements covers what lenders review.
Final Thoughts
The right oncology practice down payment depends on the program, the lender, the deal and the buyer. Rather than focusing on a single number, buyers should plan for the full cash picture, including working capital for drug purchases and the transition after closing.
