How does a construction loan for a duplex, triplex or fourplex work?

By David Hodara ·

Short Answer

The lender funds part of the land and most of the build, releasing construction money in draws as inspected stages are completed, and you pay interest only on what has been drawn. Passy Capital finances 2-4 unit ground-up builds up to 85% of total cost, for 12 to 24 months, from $1M to $5M. The loan is repaid by selling the units or refinancing into a DSCR loan.

A 2-4 unit building is the step up from a single spec home: more rent or more sale value from one lot, one foundation and one roof. The financing is a ground-up construction loan, structured the same way as for a single house, but the lender looks harder at zoning, the unit mix and the exit, because the buyer pool and the rental math are different.

How the money moves

The draw schedule entry covers inspections, retainage and timing in detail.

  • At closing, the loan funds its share of the land (or credits the land you own toward your equity) and closing costs
  • You put in your equity first; on a project at the maximum that is 15% of total cost
  • The builder completes a stage: foundation, framing, dry-in, mechanicals, finishes
  • An inspector confirms the stage, and the lender releases that stage's funds
  • Interest accrues only on what has been drawn, so payments grow as the building does
  • At completion, the units are sold or let, and the loan is repaid by the sale or by a DSCR refinance

What is specific to 2-4 units

  • Zoning: the lot must allow the number of units you plan. Many single-family zones do not, and a rezoning is not something a construction loan waits for
  • Exit by sale: can the building be sold as a whole, or can the units be sold separately as condominiums or townhomes? The answer changes the appraisal
  • Exit by refinance: a DSCR loan up to 80% LTV is sized on the combined rents, so market rents per unit have to be supported
  • Utilities and fire separation: separate meters and code requirements between units add cost that belongs in the budget
  • Builder: a licensed general contractor who has built multi-unit residential, not only single-family homes

What the lender needs

See construction loans for the product and what a lender needs for a spec build for how a lender reads a builder's file. A construction loan calculator gives a first view of the interest carry.

  • Site control and zoning confirmation
  • Plans, specifications and permits, or a realistic permit timeline
  • A line-item budget with a contingency, and the general contractor's contract
  • Your track record, or the builder's, on similar projects
  • The exit: comparable sales or rents for new 2-4 unit buildings nearby
  • Proof of equity and reserves to cover overruns and carry

A worked example

A lot bought for $400,000 and a fourplex budgeted at $1,600,000 make a total cost of $2,000,000. At 85% LTC the loan can reach $1,700,000, and your equity is $300,000, often largely covered by the land if you already own it. The building budget is released in draws over the build. At completion, a sale repays the loan, or a DSCR refinance up to 80% of the appraised value of the let building does.

The arithmetic is at the published maximum; the actual loan depends on the appraisal, the plans and your experience.
