How to Finance a Home Services Acquisition: SBA Loans, Seller Financing, and What Actually Works

Most home services owners who decide to acquire have already worked out the target, the deal structure, and the valuation. What keeps them up at night is a much simpler question: how do I actually pay for this?

Figuring out the financing is often harder than finding the deal itself. An SBA loan requires documentation and a personal guarantee. Seller financing requires negotiation and trust. A conventional bank loan demands revenue history and EBITDA stability that smaller operators may not have. Self-funding means pulling capital out of your existing business. And if you get the financing structure wrong, a deal that makes sense on paper can become financially dangerous in practice.

This guide covers how financing actually works for home services acquisitions — which options work for which deal sizes, what lenders are actually looking for, and how to structure your financing so the deal works without crippling your existing business.

The Financing Options That Actually Work in Home Services M&A

In our experience working with home services owners on acquisitions, the financing depends almost entirely on deal size. A $300K acquisition looks nothing like a $3M acquisition, and the financing strategy that works for one will fail for the other.

For very small deals — under $500K — owners typically self-fund or take an SBA loan. For mid-market deals — $500K to $3M — owner capital plus SBA or conventional bank financing is common, often blended with some seller financing. For larger deals — $3M and above — seller financing becomes a much bigger component of the structure, because a 100 percent bank-financed acquisition at that size makes the debt service burden unsustainable.

The core principle is simple: the larger the deal, the more the seller needs to have skin in the game through financing. This is not just a lender requirement — it is economics. If you are acquiring a $5M company and trying to finance the entire purchase at market interest rates, your debt service could easily exceed the target company’s standalone EBITDA, making the acquisition immediately accretive to debt but not to earnings.

SBA 7(a) Loans for Business Acquisitions

For most home services owners doing their first or second acquisition under $2M, the SBA 7(a) loan is the most accessible financing option.

Here is how it actually works. The SBA does not lend the money directly — an SBA-approved lender (usually a community bank or credit union) makes the loan, and the SBA guarantees 75 to 85 percent of the loan amount if the borrower defaults — 85 percent on loans up to $150K, 75 percent above that. This guarantee makes the bank much more comfortable lending to a business acquisition, which from a traditional lending perspective is riskier than a working capital loan or equipment financing.

For an SBA 7(a) business acquisition loan, lenders typically require a down payment of 10 to 20 percent of the purchase price. You provide the down payment from your own capital, the SBA loan covers the remaining 80 to 90 percent, and the acquisition is structured as an asset purchase with the SBA loan held at the acquirer level — meaning it is your company’s debt, not the target company’s debt.

From our client work: most SBA lenders we see want to see at least three to five years of tax returns from your existing business, demonstrating stable or growing revenue and consistent EBITDA. They also want to see that your existing business is generating enough cash flow to service both your current debt (if any) and the new acquisition debt. If your existing company is barely cash-flow positive, or if you have maxed out your existing credit facilities, the SBA lender will view you as too risky.

Credit score matters, but less than most owners think. For a conventional bank loan, you probably need a score above 700. For an SBA loan, lenders are more concerned that you do not have a history of defaulting or poor credit decisions — a score of 650 with a clean payment history can work, but a score of 750 with three recent late payments will not.

The SBA application process takes time. Expect four to eight weeks from application to funding, assuming clean financials and no red flags. The paperwork includes your personal tax returns for the last three years, business tax returns, bank statements, detailed financial projections for the combined entity, and a personal financial statement. Some lenders want to see a detailed integration plan and proof that you have researched the target market.

One often-overlooked point: the SBA loan is secured by a personal guarantee. If your company defaults, the lender can come after your personal assets. This is why lender scrutiny is high — they know they have recourse if things go wrong. It also means that SBA lending is not available for very large deals where your personal net worth would not be sufficient to guarantee the loan meaningfully. There is also a hard ceiling: the 7(a) program caps loans at $5 million, so acquisitions above that size need conventional or seller financing regardless of your qualifications.

Conventional Bank Loans

If your company is large enough, a conventional bank loan — not SBA-backed — may be faster and cheaper than an SBA loan.

Conventional bank loans for business acquisitions typically require that your company be generating at least $5M in annual revenue with several years of stable, documented EBITDA. The bank wants to see that your company is large and established enough that an acquisition-sized debt load is manageable within your cash flow. For a $2M acquisition on top of a $20M company generating $3M in EBITDA, that is different arithmetic than a $2M acquisition on top of a $6M company generating $600K in EBITDA.

Conventional bank loans also move faster than SBA loans — many banks can approve and fund within two to three weeks if the documentation is clean. They often have lower interest rates than SBA loans, sometimes by 100 to 200 basis points, because the bank’s risk is lower and the SBA guarantee is not needed.

The tradeoff is stricter qualification. Most banks want to see a detailed debt service coverage ratio (DSCR) showing that your combined company, post-acquisition, can service all debt — existing and new — at 1.25x or higher. If your existing company is leveraged near its limit, the bank will not lend you the money to buy an acquisition, no matter how good the target is. This is why many mid-market acquisitions require blended financing — some bank debt, some SBA debt, and often some seller financing to fill the gap.

Also note: unlike the SBA loan, conventional bank loans for acquisitions are sometimes structured as acquisition facility loans that mature quickly (two to three years), forcing you to refinance into permanent financing once the acquisition is closed and integrated. This is because banks view acquisition debt as temporary bridge financing. If you refinance too quickly after close, your refinance lender will want to see actual operating results from the combined entity, not pro forma projections — so plan for a bridge period where you are carrying higher interest rates.

Seller Financing

Seller financing is far more common in home services acquisitions than most buyers realize, especially for larger deals.

Seller financing works like this: you pay the agreed-upon purchase price, but instead of paying all of it at close with bank proceeds, the seller accepts a promissory note for part of the purchase price. For example, on a $1M deal, you might pay $400K in cash (from a bank loan and your own capital) and finance the remaining $600K from the seller over three to five years at an agreed-upon interest rate — in the current rate environment, most seller notes run 7 to 10 percent.

From a seller’s perspective, this accomplishes several things. First, it reduces the lender’s credit risk on your bank loan — a bank is much more comfortable lending 60 percent of a deal’s purchase price than 100 percent, because your equity cushion is larger. Second, the seller retains a financial interest in the business performing well — if you run the acquired company into the ground and cannot pay the note, the seller loses the deferred portion of their sale price. Third, depending on the seller’s tax situation, spreading the sale proceeds over multiple years may reduce their tax burden versus taking a lump sum.

Seller financing is most common on deals where the seller is staying somewhat involved — they may retain a small equity stake, act as a consultant during integration, or remain employed as a technician or operations person. In those cases, the seller has confidence that you will run the business competently, and they benefit from the sale economics (the interest payments) and the business performance.

The mechanics matter. Seller notes typically include a personal guarantee from you (the buyer), a lien on the acquired company’s assets, and specific covenants — requirements that you maintain certain financial ratios, do not take on additional debt above a certain threshold, and provide the seller with quarterly or annual financial statements. Some seller notes include an acceleration clause: if you miss a payment or breach a covenant, the entire remaining balance becomes immediately due.

A 2025 rule change to know if you are pairing a seller note with an SBA loan: under the SBA’s current rules (SOP 50 10 8, effective June 2025), a seller note only counts toward your required 10 percent equity injection if it is on full standby — no principal or interest payments — for the entire life of the SBA loan, and it can cover no more than half of that injection. A seller who keeps less than 20 percent ownership must personally guarantee the loan for two years, and partial buyouts where the seller rolls equity must be structured as stock purchases. If your deal structure leans on a seller note, get your SBA lender’s read on it before you sign the LOI.

One critical point: seller financing does not replace bank due diligence. Even if the seller is willing to take back part of the purchase price, your bank will still require a full due diligence review of the target company’s financials and operations. The bank needs to know that the acquired company can service debt — both the bank’s portion and the seller note.

Self-Funding and Internal Capital

Some acquisitions are funded entirely from the buyer’s existing cash and available credit.

Self-funding works best when the acquisition is relatively small compared to your existing business, and when your business generates strong cash flow. If you are a $10M company generating $2M in EBITDA and you want to acquire a $400K acquisition, paying cash makes sense — the acquisition is small enough that it does not strain your working capital, and you maintain maximum financial flexibility.

The risk of self-funding is that you are stripping capital out of your existing business. Home services companies need cash for trucks, tools, inventory, and payroll. If you pull $500K out of your operating account to fund an acquisition, that $500K is no longer available for growth in your existing business, equipment maintenance, or managing seasonal cash flow fluctuations. Many owners who self-fund acquisitions end up having to take a bank loan later anyway, when they realize they have hurt their working capital position.

A better approach for most mid-sized acquisitions: use some internal capital (enough to show skin in the game and improve the bank’s comfort) and layer in external financing for the remainder. A 30 percent down payment from your own capital, an SBA or bank loan for 50 percent, and seller financing for 20 percent is a balanced structure that lets you fund the acquisition without crippling your existing operation.

Earnouts and Creative Deal Structures

Not all acquisitions are structured as simple one-time purchases. Some deals include earnouts — contingent payments based on the acquired company’s performance post-close.

An earnout typically works like this: you agree to pay a base purchase price at close, plus additional payments over one to three years based on whether the acquired company hits certain financial targets. For example, you might pay $600K at close, with an additional $200K payable over two years if the combined entity achieves $2M in revenue and 15 percent EBITDA margins. The earnout de-risks the acquisition for you by tying part of the payment to actual performance.

From our client work: earnouts are usually structured around revenue or EBITDA targets, not customer retention (which is harder to measure fairly). The most common structure is a revenue-based earnout — you pay an additional amount per dollar of the acquired company’s revenues that exceed a baseline. This aligns incentives: the seller wants the business to succeed and retain customers so they earn their earnout, and you want to integrate effectively so the target company does indeed hit the revenue targets.

Earnouts reduce the amount of financing you need at close, which can make a deal possible that would not be possible otherwise. If a $1M acquisition looks too expensive at a 3x EBITDA multiple, an earnout structure — $600K at close plus $400K earnout — makes the deal more palatable. You prove you can operate the target successfully before paying full price.

The tradeoff is complexity. Earnout disputes are common. Sellers often feel that you have not done enough to hit the earnout targets, or that you have deliberately starved the acquired company of resources to suppress revenue. To minimize disputes, earnout provisions need to be extremely specific: exactly which revenue counts toward the earnout, how it is measured, when it is calculated, and what happens if there are disputes. Many lawyers recommend having an independent accountant validate earnout calculations rather than letting buyer and seller fight about it.

How to Match the Financing to the Deal

Choosing the right financing structure depends on four factors: deal size, your company’s cash flow and leverage position, the seller’s willingness to finance, and your timeline.

For deals under $500K: SBA loan or self-funding are your primary options. If your company has stable cash flow and the acquisition is small relative to your revenue, self-funding is simpler and faster. If you need to preserve cash or want to leave your credit facilities untouched, an SBA loan takes longer but keeps your balance sheet flexible.

For deals $500K to $2M: Most of these are financed with a blend: your equity (20 to 30 percent down), an SBA or conventional bank loan (50 to 60 percent), and seller financing (10 to 20 percent) if available. This is the most common structure we see, because it balances lender comfort, your capital preservation, and the seller’s interest in seeing the deal work.

For deals $2M to $5M: Conventional bank financing becomes more available if your company meets the size and profitability thresholds. You will likely need a blended approach: your equity (25 to 30 percent), bank debt (40 to 50 percent), and significant seller financing (20 to 35 percent). At this deal size, the seller’s willingness to finance becomes critical to the deal working — if they want all cash, you may not be able to finance it without putting excessive leverage on your company.

For deals above $5M: These almost always require seller financing as a major component. The debt service on 100 percent bank financing of a $5M+ acquisition is typically unsustainable. A typical structure is: your equity (15 to 25 percent), bank financing (40 to 50 percent), and seller financing (25 to 40 percent). You may also see earnouts, performance-based adjustments, and rollover equity (where the seller retains a small ownership stake in the combined entity).

Start the financing conversation early — before you sign an LOI with the target company. Talk to your bank or SBA lender about what they would be comfortable lending, and understand your company’s debt capacity. Have a preliminary conversation with the seller about their expectations for payment terms. This groundwork prevents the situation where you fall in love with a deal, sign the LOI, and then discover you cannot actually finance it.

Also be realistic about timing. SBA loans take four to eight weeks. Due diligence on anything larger than $500K typically takes four to eight weeks as well. If you need to close in 60 days, SBA financing is risky — you may run out of time. For a faster close, self-funding or a bank loan (if your company qualifies) are better options.

Finally, model the debt service carefully. Your combined company needs to generate enough cash flow to service all debt — existing and new — and still have cash left over for growth, equipment maintenance, and contingencies. A common mistake is financing a deal at a debt level that works for the first year but becomes unsustainable in year two if customer retention is lower than projected, or if integration costs more than expected.
