Most acquisition deals don't die because the buyer can't qualify. They die because the buyer is $50,000 to $100,000 short on injection — and nobody told them there are legitimate, lender-accepted ways to close that gap before the letter of intent even goes out.
If your buyer has $120,000 liquid and needs $200,000 at the table, here is exactly where the other $80,000 can come from.
Why the Equity Gap Exists in the First Place
SBA 7(a) loans require a minimum equity injection of 10% of the total project cost for most business acquisitions. On a $1 million deal with $800,000 in SBA financing, that's a $200,000 equity requirement — not $200,000 in cash from a single source. Lenders and SBA both accept equity injections from multiple sources, provided each source is properly documented and the funds are verified as belonging to the borrower (or are structured in a way SBA approves).
The key phrase in SOP 50 10 8 is "from an acceptable source." That's where the strategy lives.
Source 1: Seller-Held Debt (Seller Note on Standby)
This is the most common bridge for the equity gap, and it is explicitly permitted under SBA guidelines — with conditions.
A seller agrees to carry back a portion of the purchase price as a promissory note. For the note to count toward the buyer's equity injection, it must be on full standby for the life of the SBA loan — meaning no principal or interest payments during that period. Some lenders will allow a partial standby structure (interest-only payments after 24 months), but full standby is the cleanest path to approval.
Example: Buyer needs $200K injection. They bring $120K cash. Seller carries $80K on standby for 10 years. Lender counts the $80K as equity. Deal closes.
The seller must understand they are subordinating to the SBA lender — no payments until the 7(a) loan is fully paid off or forgiven. That conversation needs to happen early, ideally before the LOI is signed. Sellers who balk at full standby will sometimes accept a reduced purchase price instead; that negotiation is worth having.
Source 2: Gift Funds from a Family Member
SBA allows gift funds as an equity injection source, provided the gift is properly documented. The donor must provide a signed gift letter stating:
- The amount of the gift
- That the funds are a gift, not a loan
- That no repayment is expected
The lender will verify the donor's ability to make the gift (bank statements showing the funds exist) and trace the transfer into the borrower's account. The funds need to season in the borrower's account — most lenders want 60 days of statements showing the deposit.
Gift funds are cleaner than they sound, but they require paperwork discipline. Missing documentation is the number-one reason gift funds get kicked back at underwriting.
Source 3: Home Equity (HELOC or Cash-Out Refi)
A buyer who owns a home with equity can tap it via a home equity line of credit or a cash-out refinance to generate liquid capital. This is perfectly acceptable to SBA lenders because the funds become cash in the borrower's account — they document like any other verified liquid asset.
The practical consideration: the HELOC or refinance must close and fund before the business acquisition closing. Lenders want to see the cash sitting in the buyer's account, not a commitment letter from a mortgage company.
Current HELOC rates (as of mid-2025) are running roughly 7.5%–9% variable, so the buyer is adding a second cost layer. Model that against the business's cash flow before recommending this route. A business generating $180,000 in SDE that's already servicing a $800,000 SBA note doesn't have unlimited room for a $400/month HELOC payment on top.
Source 4: 401(k) / IRA Rollover (ROBS)
Rollover for Business Startups — ROBS — allows a buyer to invest retirement funds into a C-corporation that then purchases the business, without triggering early withdrawal penalties or ordinary income taxes at the time of the rollover. The buyer's retirement account buys shares of the new C-corp; the C-corp uses that capital as the equity injection.
ROBS is IRS-recognized but administratively complex. You need a specialized ROBS provider to set up the structure — costs typically run $4,000–$5,000 in setup fees plus $100–$200/month in ongoing administration. IRS scrutiny on ROBS plans is real; the plan must be a legitimate, functioning retirement plan, not a shell.
Do not attempt a ROBS structure without engaging a qualified ROBS administrator and having your CPA review the plan before closing. This is not a DIY exercise.
ROBS is most appropriate when the buyer has substantial retirement savings (typically $80,000 or more in the account), limited liquid cash, and doesn't want to take a taxable distribution.
Source 5: Unsecured Personal Loans or Business Credit Lines (Pre-Closing)
Some buyers take out personal loans or leverage existing personal credit lines to generate cash before closing. This is permitted as an equity source, but lenders will scrutinize it carefully.
The concern: if the buyer borrowed the injection money, their personal debt load just increased — which affects the global cash flow analysis. Lenders running a personal financial statement will see the new liability and factor it into the debt-service coverage calculation.
The rule of thumb most underwriters apply: if the borrowed funds create a monthly obligation that materially impairs the buyer's personal cash flow, expect pushback. A $20,000 personal loan at $400/month on a buyer with $8,000/month in W-2 income is manageable. The same loan on a buyer with $3,500/month in take-home pay is a problem.
Stacking Sources: How Lenders Actually View It
None of these five sources are mutually exclusive. The cleanest deals often stack two or three:
- $90,000 buyer cash
- $50,000 seller note on standby
- $60,000 HELOC proceeds
Total injection: $200,000. All documented. All acceptable.
What lenders want to see is a clear paper trail for every dollar. Each source gets its own documentation package: bank statements for cash, gift letter plus donor statements for gifts, note and subordination agreement for seller debt, HELOC closing disclosure for home equity proceeds.
Start building that documentation file at the same time you're negotiating the purchase agreement — not two weeks before closing.
What Doesn't Work
A few sources that come up in conversations and don't pass SBA muster:
- Borrowed funds from another person presented as a gift. If the "gift" has any expectation of repayment — verbal or written — it's a loan. Misrepresenting it is loan fraud.
- Funds from the business being acquired. You cannot use the target company's cash or credit lines to fund your own down payment. The business's assets belong to the seller until the deed transfers.
- Crowdfunding proceeds without proper documentation. Not categorically disqualified, but almost impossible to document to SBA standards.
The Practical Takeaway for Brokers and Buyers
An equity gap is a structuring problem, not a deal-killer. The solution set is well-established: seller notes, gift funds, home equity, ROBS, and personal credit. The execution is in the documentation, the timing, and making sure every source clears the lender's "acceptable source" test before you're two weeks from closing and scrambling.
If your buyer is short on injection, bring the conversation to your lender or broker early — ideally at the same time as the purchase agreement, not after the LOI is countersigned. The earlier the gap is identified, the more options remain on the table.
