"Wait, it's too small to qualify?" Dev (a made-up builder, 27) runs Copperleaf Builds (a made-up general contractor in Columbus, Ohio). He'd just bought a tired duplex for $300,000 to renovate and sell. His scope of work came to $90,000, and he asked his bank for an SBA Builders CAPLine to cover it. The answer was no. The job was $10,000 too small.
This is general information, not legal or financial advice. Confirm every rule with your lender and the current SOP before you apply.
The one tip
On a Builders CAPLine, renovation has to be big. The cost of the work must equal or exceed one-third of the property's purchase price. Then the line is sized from your written cost proposal, never from the price you hope to sell for.
Under SBA SOP 50 10 8.1 (effective October 1, 2026), Section B, Chapter 4:
- Renovation must be "prompt and significant." Work starts within a reasonable time after approval, and its cost must be at least one-third of the purchase price.
- Only on-site work counts: the structure, utility connections and landscaping. Staging furniture and marketing don't.
- Proceeds pay direct costs like labor, materials, equipment rental, permits and inspection fees. Land is eligible only if it's no more than 33% of project cost.
- Proceeds can't buy vacant land for someday, hold rentals, or refinance debt.
- The final sale must be arm's length, to an unaffiliated buyer.
- Interest gets paid at least every six months from your own cash, not from the line.
Worked example
All numbers are made up.
- Purchase price: $300,000, with a $240,000 first mortgage from another lender and $60,000 of Dev's cash.
- Original scope: $90,000. One-third of $300,000 is $100,000. Short by $10,000, so the project isn't eligible.
- The roof had been on his "maybe" list at $14,000. Moving it into the written proposal brings the scope to $104,000.
Now the line: $104,000, based on that written cost proposal. Dev hopes to sell for $450,000. The sale price never sets the line.
The bank takes a second lien behind the purchase mortgage, which SBA allows when the first lien bought the property. But there's a cap. The payoff needed to release both liens can't exceed 80% of the completed project's fair market value. An appraiser puts the finished duplex at $450,000, and 80% is $360,000. Dev's $240,000 plus $104,000 is $344,000. He clears it by $16,000.
SBA's guaranty on a loan of $150,000 or less is up to 85%, so $88,400. If the line matures in 12 months or less, SBA's upfront fee is 0.25% of the guaranteed portion: $221.
Interest is an assumption: 10.5% on about $60,000 drawn, on average, over eight months is roughly $4,200. Dev has to pay that from his own account. If his cash plan assumed the line would cover its own interest, the deal stalls before the drywall.
How the money moves
Draws come as work is done, not up front. Each one needs an architect, appraiser or engineer to certify the stage and a lender officer to inspect it. A draw can't exceed 100% of the certified cost, and it needs contractor statements and lien waivers. Final lien waivers from every sub and supplier come before the last draw.
Repayment is due at sale or within 36 months after completion, whichever comes first.
Do this week
- Divide your purchase price by three. If your written scope is under that number, the project doesn't qualify yet.
- Strip anything that isn't on-site work from the cost proposal before you count.
- Get three letters lined up: a mortgage lender confirming buyers can get financing, a real estate broker confirming a market exists, and an architect, appraiser or engineer agreeing to certify draws.
- Run the 80% test: first mortgage plus your line, divided by the appraised completed value.
- Budget six months of interest in cash, outside the line.
- Ask which conditions are SBA's and which are bank overlays.
