A construction loan is not a mortgage with a different name. A mortgage funds a house that already exists and is secured by a thing an appraiser can walk through. A construction loan funds a house that does not exist yet, secured by a lot and a set of drawings, and the lender's entire job is to release money in stages against work that has actually been completed. Everything unusual about construction financing follows from that one difference, and owners who understand it stop being surprised by the paperwork.
This article deepens the new-construction guide. It assumes you have chosen a builder using the logic in the builder selection guide, and that the entitlement and permitting side is understood from the Claremont permit field guide - because a lender will want to see that path is real before funding anything.
How the money actually moves
Construction lending runs on DRAWS. The loan is approved for a total amount, but the borrower does not receive it at closing. Instead the money is released in scheduled instalments as defined stages of work are completed - typically foundation, framing, rough mechanical, drywall, finish, completion - with the exact schedule agreed up front and written into the loan documents.
Each draw is verified. The lender or its inspector visits the site, confirms the work claimed has been performed, and only then authorises release. This is slower than borrowers expect and it is also the mechanism that protects them: a lender inspecting progress before paying is a second set of eyes on whether the job is where the invoice says it is.
Interest usually accrues only on the amount DRAWN, not the full approved sum, which is why the early period feels cheap and the later one does not. Borrowers who budget as though the whole loan is carrying from day one over-reserve; borrowers who budget as though the early figure is the figure get an unpleasant surprise near completion. Model it against the draw schedule, with your lender, before you sign.
Two structures exist. A CONSTRUCTION-TO-PERMANENT loan closes once and converts to a long-term mortgage on completion. A CONSTRUCTION-ONLY loan is a short-term facility that must be paid off by a separate permanent loan you arrange afterwards. Single-close means one set of closing costs and one underwriting event, which matters because your circumstances and the lending environment can both change while a house is being built. Two-close means more flexibility to shop the permanent loan at the end, and more exposure to whatever conditions exist at that point. Neither is universally right; ask your lender to price both.
What lenders want before they say yes
Construction underwriting looks at more than a borrower, and the extra scrutiny falls on the PROJECT.
THE BUILDER IS UNDERWRITTEN TOO. Lenders review the contractor's licence, insurance, financial standing, and history of completed work. A builder a lender declines is a builder worth a second look, and that free opinion is one of the underrated benefits of institutional financing.
THE PLANS AND THE CONTRACT MUST BE COMPLETE. Complete drawings, a detailed specification, and a fixed-scope contract with a defined price and a change-order mechanism. Vague scope is the enemy of construction lending because vague scope is where budgets die, and lenders have seen it many times.
THE BUDGET MUST BE LINE-ITEMED AND MUST INCLUDE CONTINGENCY. Not a round number with optimism attached - a schedule tied to the draw stages, with an explicit contingency line. Lenders require contingency because they know construction budgets move; borrowers who resent it are usually the ones who later need it. Set it, fund it, and do not treat it as a discretionary fund for finish upgrades.
THE APPRAISAL IS PROSPECTIVE. The appraiser is asked to value the completed house from the plans and specifications - an as-completed opinion. In a town like Claremont, with limited turnover and considerable variety in housing stock, the comparable evidence for a specific new build can be thin, which is a real and recurring friction. Build the schedule assuming appraisal will take longer and ask more questions than it would on a resale.
THE ENTITLEMENT PATH MUST BE CREDIBLE. Lenders want to know the project can actually be approved and permitted. This is where owners underestimate the calendar, because approvals, plan check, and utility coordination all sit outside the builder's control. Requirements and processes are set by the City of Claremont and by state code and they change, so the city's planning and building counters are the authority on what your specific site and project need - not an article, and not the assumption of anyone in the transaction.
Where projects get into trouble
Almost every construction financing problem is one of four things.
SCOPE CREEP THROUGH CHANGE ORDERS. Each change costs money, and often time, and the loan amount was fixed before you started choosing tile. Changes above contingency have to come from somewhere, and that somewhere is usually the borrower's own cash. Decide the specification before construction begins, treat each proposed change as a real decision with a written price, and protect the contingency line from your own enthusiasm.
SCHEDULE OVERRUN AGAINST A TERM. Construction facilities have end dates. Extensions exist and are not free. Weather, inspection sequencing, utility connections, and long-lead materials all cause delay and none of them are unusual, which is exactly why a schedule with no slack in it is a schedule that will fail.
DRAW MECHANICS. Money is released after work is done, so the builder's own cash flow and payment terms matter. Understand who is paid when, whether the lender pays the builder directly, and how lien waivers are handled at each draw - that last item is not administrative trivia, it is how you avoid paying twice for the same work.
AND THE CONVERSION ITSELF, on a two-close structure: the permanent loan is underwritten near completion, against your circumstances and market conditions at that time, not at the start. Keep the file clean throughout. Do not change jobs, open credit, or move large sums around while a house is being built.
One local note to close. Construction here is often a lot purchase followed by a build, or a rebuild on a property already owned, rather than a purchase from a developer - so land equity, existing liens, and how the lot was acquired all become part of the financing conversation earlier than people expect. And on sloped sites the geotechnical and drainage work can be a substantial share of a budget that a lender will want documented before funding, so get those investigations done before you finalise a number.
This is general information rather than lending advice. Programme terms, underwriting standards, and city requirements vary and change; your lender, your builder's contract, and the City of Claremont govern every specific.

Frequently asked questions
How is a construction loan different from a mortgage?
A mortgage funds a house that already exists. A construction loan funds one that does not, so money is released in draws as defined stages of work are completed and verified by the lender's inspection. Interest usually accrues only on amounts drawn, so carrying costs rise as the project progresses.
What is the difference between construction-to-permanent and construction-only?
Construction-to-permanent closes once and converts to a long-term mortgage at completion, meaning one set of closing costs and one underwriting event. Construction-only is a short-term facility paid off by a separate permanent loan arranged later, which offers more flexibility to shop but more exposure to conditions at that time.
What do construction lenders require before approving a loan?
Complete plans and specifications, a fixed-scope contract with a change-order mechanism, a line-itemed budget with an explicit contingency, a prospective as-completed appraisal, and a credible entitlement and permitting path. The builder is underwritten too, including licence, insurance, financial standing and completed work.
What causes construction loans to go wrong?
Usually scope creep through change orders that exceed the contingency, schedule overrun against a facility that has an end date, draw mechanics and lien waivers being misunderstood, or - on two-close structures - the permanent loan being underwritten near completion against changed circumstances.
