Construction Loan

A construction loan is financing for building or substantially rebuilding a structure, advanced in installments as the work progresses rather than in a single disbursement. The federal banking agencies define the category in their real estate lending guidelines as "an extension of credit for the purpose of erecting or rehabilitating buildings or other structures, including any infrastructure necessary for development" (Appendix A to Subpart D of Part 34, Title 12). Regulation Z does not define the market label but it describes the product plainly, in an appendix devoted to it: "Section 1026.17(c)(6) permits creditors to treat multiple advance loans to finance construction of a dwelling that may be permanently financed by the same creditor either as a single transaction or as more than one transaction" (Appendix D to Part 1026).

The lender's problem is what makes the terms different from a mortgage on an existing house. There is no completed building to take as security, the value of the collateral changes every week, and whether the loan is ever repaid depends on work being finished by someone other than the borrower. Everything characteristic of the product, the draw schedule, the inspections before each advance, the short term, follows from that.

One name, two products, and the difference is the number of closings. A construction-only loan finances the build and falls due at completion, at which point the borrower repays it, usually by taking out a separate permanent mortgage. That is two transactions, two sets of closing costs, and a second underwriting at whatever rates apply when the house is finished. A construction-to-permanent loan is written so that the construction phase converts into the long-term mortgage without a second closing. The trade is the ordinary one: a single closing removes the risk that the borrower cannot qualify or cannot bear the rate a year from now, and the borrower pays for that certainty in the terms.

Regulation Z treats the two differently, in two adjacent paragraphs, and both carve-outs are narrow. For purposes of paragraphs (c) through (f) of 12 CFR 1026.43, the ability-to-repay section does not apply to "[a] temporary or 'bridge' loan with a term of 12 months or less, such as a loan to finance the purchase of a new dwelling where the consumer plans to sell a current dwelling within 12 months or a loan to finance the initial construction of a dwelling" (1026.43(a)(3)(ii)), nor to "[a] construction phase of 12 months or less of a construction-to-permanent loan" (1026.43(a)(3)(iii)). Three details in those two sentences repay attention. The initial-construction loan is written as an example of a temporary loan of 12 months or less, so the 12-month limit governs it as well. The second paragraph carves out the construction phase, not the whole construction-to-permanent loan. And the exclusion is expressly scoped to paragraphs (c) through (f), so it does not travel to the rest of the regulation. The ability-to-repay duty itself is mortgage underwriting's subject, and the bridge limb of the same sentence belongs to the bridge loan page; what matters here is that a borrower building a house is outside a protection they would have had buying one.

The disclosure election, and why a borrower notices it. Where the same creditor may provide the permanent financing, "the construction phase and the permanent phase may be treated as either one transaction or more than one transaction" (12 CFR 1026.17(c)(6)(ii)). Appendix D then supplies methods for estimating the interest and the annual percentage rate when the schedule of advances is not known, because at the point of disclosure nobody knows when the money will actually go out. One of its conventions is worth knowing precisely because it is a convention rather than a prediction: where interest is payable only on amounts actually advanced, the creditor may "[a]ssume that one-half of the commitment amount is outstanding at the contract interest rate for the entire construction period." A borrower comparing disclosures should understand that the construction-phase figures are estimates built on a stated assumption, not a forecast of their own draw schedule. None of this puts construction lending outside the disclosure regime. Appendix D exists because it is inside it.

What a lender is willing to advance is shaped by supervisory guidance, and the guidance is aimed at the bank. How much of a project's cost a lender will advance is expressed as a loan-to-value ratio, and the interagency real estate lending guidelines tell institutions to set their own internal limits on it. Those internal limits "should not exceed the following supervisory limits", listing construction of commercial, multifamily and other nonresidential property at 80 percent and construction of 1- to 4-family residential property at 85 percent. Read that as a ceiling on the bank's policy rather than a rule about any one loan: the same appendix says "it may be appropriate in individual cases to originate or purchase loans with loan-to-value ratios in excess of the supervisory loan-to-value limits, based on the support provided by other credit factors", subject to identifying such loans and reporting them quarterly to the board, and caps the aggregate of all such loans at 100 percent of total capital. It also directs that where a loan funds multiple phases of the same project, "the appropriate loan-to-value limit is the limit applicable to the final phase of the project funded by the loan", while disbursements "should not exceed actual development or construction outlays".

The practical risks sit outside the loan documents. A build costs more than the estimate or runs past the term; a builder walks or fails; the finished house appraises for less than it cost to build. The financing is short-dated by design, which means the borrower's exit, whether that is the permanent mortgage or a refinance, has to exist on the day the term ends rather than at some point afterwards.

The lender approves a commitment amount against plans, a builder's contract and a projected completed value. Money is released in draws as stages are finished, each usually verified by an inspection, and interest accrues on the amount outstanding. During the build the borrower typically pays interest only. At completion the loan either falls due and is repaid, ordinarily by a permanent mortgage, or converts into that mortgage if the loan was written to do so.

A hypothetical of the interest arithmetic, which is the part that behaves differently from a mortgage. The commitment is $300,000 at a hypothetical 9% annual rate. Draws are $60,000 at the start, $90,000 in month four, and $90,000 in month seven. At the beginning of month five the outstanding balance is $60,000 + $90,000 = $150,000, so one month's interest is $150,000 × 0.09 ÷ 12 = $1,125. Had the whole commitment been advanced at closing, that month's interest would have been $300,000 × 0.09 ÷ 12 = $2,250, exactly twice as much.

That gap is the point of the structure, and it is also why Regulation Z needs an estimating convention: at disclosure the lender does not know the draw dates, so Appendix D permits it to assume half the commitment is outstanding for the whole construction period. Half of $300,000 is $150,000, which happens to be this borrower's month-five balance and will not be their month-two or month-ten balance. Figures are invented for the illustration and the rate is not offered as a market rate.

Pros

• Interest accrues on what has been drawn, so the borrower does not pay to hold money the builder has not needed yet.
• Staged advances tied to inspections give the borrower a reason to believe work was actually completed before it was paid for.
• A construction-to-permanent structure closes once, which removes a second set of closing costs and the risk of not qualifying later.
• Regulation Z's appendix means the disclosure regime has a defined method for the product rather than leaving it to each lender.

Cons

• A qualifying construction loan, and a construction phase of 12 months or less, sit outside the ability-to-repay determination, so the borrower loses the central protection an ordinary mortgage carries.
• The term is short by design, so an exit has to exist on the day it ends.
• Construction-only financing means a second closing and a second underwriting at whatever rates then apply.
• Disclosed construction-phase figures rest on an assumed draw pattern, so they will not match what the borrower actually pays.
• The borrower carries risks the loan does not solve: cost overruns, delays, a builder who fails, and a finished house that is worth less than it cost.
