Financing ground-up commercial construction
By Klark Sparks · Published · 7 min read
The short answer
Construction lending pays out in draws against inspected progress rather than as a lump sum, requires more equity than a purchase, and carries interest during construction before the building earns anything. It also needs a plan for what repays it at completion — the takeout — arranged before you start.
Part of our guide to Commercial Real Estate — what it is, what it costs, and who it suits.

Building is not buying, and the financing reflects it. A construction loan is a different product with a different shape, and the differences are the sort that cause problems when discovered late.
Money arrives in stages
Funds are released in draws as work is completed and inspected, not handed over at closing. Each draw involves a request, an inspection, approval and funding — days to a couple of weeks depending on the lender and the inspector.
Your contractor, meanwhile, expects to be paid. So you need working capital to bridge each stage, and that is above and beyond your equity contribution. It is the most consistently underestimated part of a construction project.
Interest during construction
You pay interest on what has been drawn while the building produces nothing. On a twelve-month build that is a substantial line item, and it grows as more of the loan is drawn toward the end.
Some construction loans allow interest to be capitalised into the facility rather than paid out of pocket. Ask, because it materially changes your cash requirement during the build.
The takeout
A construction loan is short-term by design and something has to repay it at completion — the takeout. Usually permanent financing on the finished building.
This has to be planned before you break ground. An SBA 504 can sometimes cover construction and convert to permanent financing, which removes the risk of arriving at completion with a facility maturing and no permanent loan arranged. Conventional construction lending more often expects you to arrange the takeout separately.
Discovering at month ten that permanent financing is harder to get than assumed, with a construction loan maturing, is the worst position in commercial property finance.
More equity, more scrutiny
- Equity requirements are higher than for a purchase, because an unfinished building is poor collateral.
- The contractor is underwritten too — experience, financial stability, sometimes bonding. A lender may decline your builder.
- Fixed-price contracts are strongly preferred over cost-plus, because they cap the lender’s exposure to overrun.
- Plans, permits and a detailed budget are required upfront, not developed as you go.
- A contingency within the budget is effectively mandatory rather than advisable.
What goes wrong locally
The same things that affect every Idaho build: permitting timelines that vary by jurisdiction, subcontractor availability competing against residential construction, and material lead times. In fast-growing markets like Chubbuck, Meridian, Star and Post Falls, trade availability is a genuine constraint rather than a formality, and a schedule built on ideal conditions will not survive.
Build schedule contingency and cost it. A three-month overrun on a construction loan is expensive in a way that a three-month overrun on a lease is not.
Should you build at all?
Worth asking honestly. Building gives you exactly what you want and carries execution risk, a longer timeline and a higher cost of capital during the process. Buying an existing building is faster, cheaper to finance and usually a compromise.
For a business with genuinely specific requirements — a particular clear height, a specific process layout, a location where nothing suitable exists — building is right. For a business that would be perfectly well served by an existing building, the premium is real and not always worth paying.

The irrigation district outranks your lender
Most commercial ground in the Treasure Valley used to be farmed, and a great deal of it is still inside an irrigation district. The annual assessment is a first lien that beats a recorded mortgage, and the lateral crossing the site is an easement nobody has to ask your permission about.

Buying an Idaho self-storage facility: the lien is the business model
A storage facility looks like a building with a long tenant list. What actually produces the income is a statutory lien in Idaho Code title 55, chapter 23 — and its timetable, its paperwork and its limits decide what a lender will lend.

The dock is the business, and the state owns the ground under it
On a navigable Idaho lake the income-producing half of a marina or resort sits over state-owned lakebed, held by an encroachment permit and a submerged land lease. Neither passes with the deed, and the lease is the one asset your lender is forbidden to take a lien on.
