Building instead of buying: how a single-close construction loan works

There are two ways to finance a house that does not exist yet. In the older structure you close twice: once on a short-term construction loan, then again on a permanent mortgage when the house is finished. In a single-close construction loan you close once, before the first shovel hits dirt, and that one loan covers the land, the construction and the permanent financing. We use the single-close version for almost every build, and this is why.

What one closing actually saves you

The second closing in a two-close structure is not a formality. It is a second underwrite — of your credit, your income and the market — six to twelve months after the first one. Anything that changed in between is now a problem: a job change, a new car payment, a credit score that slipped, rates that moved. Buyers who were approved in March have been declined in November on the same house.

With single-close, the underwriting happens once, up front. When the house is done, the Certificate of Occupancy triggers conversion to the permanent loan on the terms agreed at that first closing. There is no second application, no second set of closing costs, and no window where your financing depends on the next twelve months going smoothly.

• One closing covers land, construction and the permanent loan.
• Interest-only payments during the build, on the balance drawn to date.
• Automatic conversion to permanent financing at completion.
• Rate protection options, including a review for a float down if the market improves.
• One set of closing costs instead of two.

What you pay while the house is going up

During construction you pay interest only, and only on what has actually been drawn. Month two, when the slab is poured, is a small payment. Month eight, with the house dried in and mechanicals run, is a much larger one. The payment grows as the house does rather than arriving in full on day one — which matters if you are also paying rent or an existing mortgage while you build.

Draws: how money reaches the project

You do not receive the construction money. The project does, in stages called draws, released against milestones that somebody has verified in person or by photo. The schedule is set at underwriting and tied to the approved budget and scope.

• Title is updated and lien waivers collected with every draw, which is what keeps a mechanic’s lien off your house.
• Inspections are ordered by the construction team, not by the builder.
• Change orders are reviewed and approved before funding, not after the work is done.
• Retainage may apply until final completion.

Expect the standard milestones: site prep, foundation, dry-in, mechanicals, finishes and final. Factory-built projects add set and finish milestones.

Change orders and the contingency line

Every build has changes. The expensive version is the one where the work is already done and nobody asked. Submit the change order before the work starts, and if the budget carries contingency funds it can often be approved against that contingency, with the budget and schedule updated to match. A build with no contingency line is a build with no room for the thing you have not thought of yet.

What we lend on

Site-built homes are the standard case. Modular homes — built in sections in a factory to the residential code and assembled on site — are typically treated as real property using standard appraisal approaches, with a permanent foundation required per the plans and local code. Manufactured homes built to HUD Code can be eligible when they are titled as real property, installed on a permanent foundation, and supported by comparable manufactured homes in the appraisal.

Factory-built does not mean second-class here. It frequently means a shorter build cycle and tighter cost control, which in a market with volatile material pricing is worth real money. The documentation is simply more specific: manufacturer package, engineered foundation details, installation plan and contractor credentials for modular; HUD labels and data plate, installation documents and an engineer foundation certification for manufactured.

The lot you already own

If you bought land a few years ago, that equity can count toward the funds required, provided it holds up to valuation and title review. This is common west of Charlotte, where people buy acreage first and build later. Bring the deed and the closing statement early and we will tell you exactly what the lot is worth to the file rather than guessing at it.

Your builder has to be approved too

The builder is underwritten alongside you: experience, licensing, insurance and capacity. The packet is short — W-9 and business information, state or local contractor license where required, general liability insurance, workers compensation if applicable, and trade references with a recent project list. Builders who send it in one batch are usually reviewed within days, and they come out of it knowing the scopes and limits we can approve quickly.

The honest downsides

Single-close is not free of trade-offs. There is more documentation up front than on a purchase — plans, specifications, a line-item budget and an appraisal of a house that does not exist. Timelines slip when a builder is slow to submit draws. Product availability varies by state and scenario. And a construction loan is not the right tool for a fast cosmetic renovation; that is a renovation loan, which is a different conversation.

What you get in exchange is one underwrite, one closing, one set of costs and a payment you can see coming. For most buyers building in the Carolinas, that trade is not close.
