Explore this business · Financing options
This leased-site example assumes $200,000 in debt and $86,904 in owner equity. Funding the pump system alone is insufficient: the project also needs compatible bay equipment, site works and opening liquidity.
The pump-system figure uses a prior dated item observation. The supplier now requires a current quotation; see the price status and installed-scope check before using this budget.

Match the funding to the use
| Route | Possible role | Main limitation |
|---|---|---|
| Owner equity | Fund the deposit, opening expenses, cash cushion and required contribution. | The modeled $86,904 is a balancing assumption, not a lender minimum. |
| 7(a) lender loan | Discuss a combined equipment, improvement and working-capital request. | Eligibility and repayment capacity need lender review. SBA program guidance. |
| Equipment financing | Request an asset-specific quote; compare deposit, fees, security and term. | It may leave construction, preopening costs and the reserve unfunded. |
| 504 / CDC discussion | Consider only if the project has qualifying long-term fixed assets. | It does not finance working capital or inventory. SBA permitted uses. |
The case does not buy real estate. A property acquisition or new-build wash would need a separate project budget, ownership analysis and funding structure.
Make the repayment case visible
This case assumes a $200,000 loan at 10.0% for 120 months. The payment is $2,643.01 per month. These are scenario terms, not a quoted or approved SBA offer.
Year 1 modeled cash available before debt divided by principal and interest is 1.71x. This is a simplified reference-case coverage ratio, calculated after the change in receivables and inventory. It is not a lender underwriting ratio or an approval test. Personal obligations, tax distributions and other debt would change the assessment.
SBA describes creditworthiness and ability to repay as eligibility requirements; the lender determines the application documents for the circumstances. Official application guidance.
Resolve these before submitting a request
- A lease that permits the intended operation and installation of the equipment, with obligations and renewal rights reviewed.
- A technical condition report and matched equipment, installation and utility quotations.
- Site-specific confirmation of water supply and wastewater-discharge arrangements. EPA water-management context.
- Reconciled historical receipts if taking over an operating site; otherwise independently supported utilization assumptions.
- A lender-reviewed cash forecast that includes owner obligations, closing costs, reserves and equipment replacement needs.
Where financing can fail
An attractive equipment quote cannot compensate for an unusable site. A shorter lease, costly drainage work or unsupported utilization can change the lender’s view of the project. The lower-demand case has Year 1 coverage of 0.10x under this simplified model.
Keep funding and expenditure schedules aligned: signing a lease or paying an equipment deposit before financing is confirmed can consume the reserve intended for opening operations. Obtain lender instructions before committing funds.
Separate retrofit from a site acquisition
Compare the retained-site retrofit with purchase or major reconstruction. Property financing and civil works change both the funding uses and the repayment case.
Present two non-overlapping schedules: one-time opening uses and the monthly cash forecast. Attach quotes to the first and demand, roster and payment-timing evidence to the second. Reconcile total uses $286,904 with debt $200,000 and owner equity $86,904. If retained assets or the specification change, rerun the forecast before presenting the request.
