The short answer: From starting your search to closing usually takes six months to about a year. Finding the right business is the slow, unpredictable part. Once you sign a letter of intent, due diligence and SBA underwriting typically run 60 to 90 days to the closing table. Deals can move faster with a ready buyer and a motivated seller, but rushing the search is how people overpay.
The full timeline, stage by stage
| Stage | Typical time | What's happening |
|---|---|---|
| Prep & pre-qualification | 2 to 4 weeks | Define criteria, get pre-qualified with an SBA lender, set your budget |
| The search | 2 to 6+ months | Screen listings, do outreach, review dozens of businesses |
| First look & offer (LOI) | 2 to 4 weeks | Meet the seller, request numbers, negotiate and sign the LOI |
| Due diligence | 30 to 60 days | Verify financials, contracts, leases; quality-of-earnings review |
| SBA underwriting | 45 to 90 days | Runs in parallel, appraisal, valuation, approval (overlaps diligence) |
| Closing | 1 to 2 weeks | Purchase agreement, wire the down payment, take the keys |
| Total | ~6 to 12 months | Search length drives most of the variation |
Notice that due diligence and SBA underwriting overlap, they don't stack end to end. From a signed LOI, most well-run deals close in 60 to 90 days.
The search is the wild card
Everything after the LOI is fairly predictable. The search is not. Some buyers find their business in a month; others screen deals for a year. It depends on how tight your criteria are, how much off-market outreach you do, and how patient you can be. Most buyers look at dozens of businesses before making one offer, and that discipline is a feature, not a bug.

You can't rush the right deal into existence, but you can be so prepared that you move the instant it appears.
Get pre-qualified before you search
A lender pre-qualification takes a couple of weeks and tells you your real budget. Sellers and brokers take pre-qualified buyers seriously, and you can move fast when the right business shows up.
Diligence and underwriting: the 60 to 90 day sprint
Once your LOI is signed, the clock starts. Due diligence (30 to 60 days) is where you verify the seller's claims, financials, customer concentration, contracts, leases, and a quality-of-earnings review on larger deals. In parallel, your SBA lender underwrites the loan: business valuation, appraisal, and final credit approval, usually 45 to 90 days. Having your documents organized and a responsive lender keeps you at the fast end. See the lender's side in the SBA timeline & approval process.
What speeds it up (and slows it down)
- Faster: pre-qualified financing, tight criteria, a motivated seller, clean books, an experienced SBA-preferred lender, and responsive attorneys.
- Slower: messy financials, a seller who's not truly ready, real-estate appraisals, landlord lease assignments, and franchise-approval steps.
Plan for a year, hope for six months, and don't let a deadline push you into a bad deal. Avoid the classic pitfalls in first-time buyer mistakes.
