Quick Decision Guide

Choose a Construction Loan if:

  • Building from ground-up (new home)
  • Major addition ($150K+)
  • Limited existing home equity

Choose Home Equity if:

  • Renovation/addition under $100K
  • Have significant existing equity (30%+)
  • Want simpler process and faster funding

Quick Answer

Construction loan: for major builds/additions, draws during construction, converts to mortgage. Home equity: for renovations to existing space, lump sum, keeps current mortgage. Choose construction for new structures, equity for remodels.

The Bottom Line

Construction loans are designed for building – they release funds in stages, require project oversight, and convert to a permanent mortgage when done. Home equity products are simpler and work well for renovations when you already have equity in your home. For projects under $100K on an existing home, home equity usually wins on simplicity and cost.

When a Construction Loan Is Better

Construction Loan Advantages

  • Build with no existing equity: Loan based on completed value, not current equity
  • Ground-up construction: Only option for building new homes
  • Interest-only during build: Lower payments while constructing
  • Draw schedule protection: Funds released only as work completes
  • Built-in oversight: Inspector ensures quality at each stage
  • Converts to mortgage: One closing with construction-to-perm loans

Construction Loan Considerations

  • Complex approval: Need detailed plans, permits, licensed contractor
  • Higher rates: Often 0.5-1% above standard mortgages
  • Multiple closings: Some require two closings (extra costs)
  • Draw process: Funds released in stages with inspections
  • Stricter credit requirements: Usually 680-700+ minimum
  • Longer timeline: 30-60 days to close, then construction period

Best Construction Loan Scenarios

  • Building a new home: No existing structure to borrow against
  • Major additions ($150K+): Room additions, second stories, ADUs
  • Limited existing equity: Can’t access enough through home equity
  • Gut renovations: Project scope requires staged funding and oversight
  • Spec builders: Building to sell (investment property)

Example: $200,000 Second-Story Addition

Construction loan approach:

  • Loan: $200,000 at 8% construction rate
  • During 8-month build: Interest-only on drawn funds (~$667-1,333/month as draws progress)
  • Converts to 30-year mortgage at 6.75%: $1,297/month
  • Total construction-period interest: ~$8,000

Why construction loan works here: Project is large enough that you may not have $200K in accessible equity. Draw schedule ensures contractor is paid as milestones complete. Interest-only payments during build keep costs manageable while you can’t fully use the space.

Types of Construction Loans

TypeHow It WorksBest For
Construction-to-PermanentOne loan, one closing. Converts to mortgage when done.Most homeowners. Saves on closing costs.
Construction-OnlySeparate construction loan, then refinance to mortgage.Those who want to shop rates after building.
Owner-BuilderYou act as general contractor.Experienced builders. Hard to qualify.
Renovation ConstructionFor major rehabs on existing homes.Gut renovations, major structural work.

When Home Equity Is Better

Home Equity Advantages

  • Simpler process: Standard underwriting, no construction oversight
  • Faster funding: 2-4 weeks vs 30-60 days
  • Lower closing costs: No double-closing or construction fees
  • Flexible use: No draw schedule – use funds as needed
  • Lower credit requirements: 620+ for many HELOCs
  • Fixed rate option: Home equity loans offer payment certainty

Home Equity Considerations

  • Limited by current equity: Can only borrow what you’ve built
  • Full payments immediately: No interest-only period
  • Variable rate risk: HELOCs can increase with rates
  • Can’t build new: Requires existing home as collateral
  • No built-in oversight: You manage contractor directly

Best Home Equity Scenarios

  • Renovations under $100K: Kitchen remodels, bathroom updates, finished basements
  • Smaller additions: Sunrooms, bump-outs, enclosed porches
  • Significant existing equity: 30%+ equity gives you borrowing power
  • Want control over funds: No draw schedules or inspections
  • Multi-phase projects: HELOC lets you draw as needed over time
  • ADU construction: If you have enough equity and want simpler process

Example: $75,000 Kitchen Renovation

Home equity loan approach:

  • Loan: $75,000 at 8% fixed for 15 years
  • Monthly payment: $717 (starts immediately)
  • Total interest over life: $54,060
  • Closing costs: ~$2,500

Why home equity works here: If your home is worth $400K with $280K mortgage, you have $120K in equity. A $75K home equity loan is well within reach. You get funds faster, avoid construction loan complexity, and have a fixed payment. Total cost is lower than a construction loan for this size project.

The Crossover Point

For most homeowners with adequate equity, $100K-$150K is the threshold where construction loans start making sense. Below that, home equity products are simpler and cheaper. Above that, especially for structural work or new construction, the construction loan’s draw schedule and oversight become valuable.

Frequently Asked Questions

Should I get a construction loan or home equity loan for an addition?

For additions under $100K, a home equity loan or HELOC is usually simpler and cheaper. You avoid construction loan fees, get funds faster, and don’t need the draw schedule structure. Construction loans are better for large additions ($150K+), ground-up builds, or when you don’t have enough existing equity to borrow against.

What credit score do I need for a construction loan?

Construction loans typically require 680+ credit scores, with the best rates requiring 720+. Requirements are stricter than standard mortgages because lenders take more risk financing something that doesn’t exist yet. Home equity products may accept lower scores (620+ for HELOCs).

How do construction loan draws work?

Construction loans release funds in 4-6 stages (draws) as work is completed. Before each draw, a lender-hired inspector verifies the work meets plan specifications. Common draw schedule: foundation, framing, rough-in (electrical/plumbing), drywall, final completion. You only pay interest on funds already disbursed.

Can I use a HELOC for new construction?

No, HELOCs require an existing home as collateral, so they can’t fund ground-up new construction. However, you can use a HELOC for additions, major renovations, ADUs, or any construction on a property you already own with sufficient equity.

What is a construction-to-permanent loan?

A construction-to-permanent (C2P) loan combines the construction phase and permanent mortgage into one loan with one closing. During construction, you make interest-only payments on disbursed funds. When construction completes, the loan automatically converts to a standard 15 or 30-year mortgage. This saves money versus closing twice.
