DSCR Investing Near New Highway and Transit Projects

The Infrastructure Investment and Jobs Act (IIJA) authorized $1.2 trillion in federal spending, with $550 billion in new funding above baseline. That money is now flowing into highways, bridges, rail expansions, and transit systems across the country. Between 2022 and 2026, over 66,000 infrastructure projects received funding commitments.

For DSCR investors, these projects represent a predictable catalyst for rental demand and property appreciation. Construction workers need housing. New transit stations create walkable neighborhoods. Highway expansions open up previously inconvenient suburbs to commuters.

The key is timing, location, and knowing how to underwrite a property that hasn't yet benefited from the infrastructure investment next door.

Why Infrastructure Projects Drive Rental Demand

Infrastructure spending creates rental demand through three distinct channels:

Construction Phase Demand (1-5 years)

Major projects bring thousands of temporary workers who need housing. The $16 billion expansion of I-35 in Texas is expected to employ 5,000-8,000 workers during peak construction. These workers need furnished rentals, short-term leases, and housing close to the project site.

• Typical construction worker housing budget: $1,200-$2,000/month
• Average project duration: 3-7 years for major highway and transit builds
• Workers often prefer single-family rentals or duplexes over hotels for multi-year projects

Accessibility Premium (Permanent)

Once a highway interchange, bridge, or transit station opens, properties nearby become more accessible. Research from the American Public Transportation Association shows that residential properties within a half-mile of transit stations appreciate 4-24% more than comparable properties farther away.

• New highway interchanges in previously underserved areas increase commuter access
• Light rail and BRT (bus rapid transit) stations create walkable nodes
• Bridge replacements and capacity expansions reduce commute times, expanding the viable rental radius for employment centers

Economic Multiplier Effect (5-15 years)

Infrastructure spending attracts commercial development. A new transit station attracts retail, which attracts employers, which attracts residents. The Federal Highway Administration estimates that every $1 billion in highway spending creates approximately 13,000 direct jobs and supports an additional 15,000 indirect jobs.

Major Projects Worth Tracking in 2026

Here are active infrastructure projects with the highest potential impact on nearby rental markets:

Highway Expansions:

• Phoenix South Central Light Rail (Phoenix, AZ): $2.1 billion. Extension through South Phoenix.

How to Identify the Investment Zone

Not every property near a construction project is a good investment. The sweet spot is specific:

The Goldilocks Distance

• Too close (under 0.25 miles): Construction noise, dust, and disruption depress rents during the build phase and may create permanent noise issues for highway projects
• Sweet spot (0.5-1.5 miles): Close enough to benefit from access, far enough to avoid nuisance
• Too far (over 2 miles): Benefits dissipate, especially for transit projects where walkability matters

Transit-Specific Positioning

For rail and BRT stations, the research is clear:

• 0.25-0.5 miles from station: Maximum appreciation premium (10-25% above baseline)
• 0.5-1.0 miles: Moderate premium (5-15%)
• 1.0-1.5 miles: Marginal premium (2-8%)
• Beyond 1.5 miles: No measurable transit premium

Highway-Specific Positioning

For highway interchanges and expansions:

• Near new interchanges in growing suburbs: Highest upside—these create new commuting corridors
• Along capacity expansions: Moderate upside—reduced congestion makes existing areas more desirable
• Near construction zones during build phase: Temporary depression, long-term appreciation

Timing Your Purchase: The Infrastructure Investment Timeline

Timing is everything with infrastructure plays. Here's the typical lifecycle:

Phase 1: Announcement (Best Entry Point)

• Project receives funding approval or breaks ground
• Local awareness is low
• Property prices haven't moved yet
• DSCR loans can be secured at current (lower) appraised values
• Risk: Project delays or cancellation (mitigate by buying only after federal funding is obligated)

Phase 2: Construction (Second-Best Entry)

• Workers arrive and need housing
• Short-term rental demand spikes
• Local businesses start opening
• Prices begin rising but haven't peaked
• DSCR may benefit from higher achievable rents during construction

Phase 3: Completion (Appreciation Harvest)

• Station opens or highway expansion completes
• Property values jump as accessibility improves
• Permanent resident demand stabilizes at higher levels
• Refinance opportunity to capture increased appraised value

Phase 4: Maturation (3-5 years post-completion)

• Commercial development fills in around transit stations
• Neighborhood character solidifies
• Highest sustained rents and lowest vacancy rates
• Potential to sell at peak or hold as a stabilized asset

Underwriting Infrastructure-Adjacent Properties With DSCR

When analyzing these deals, adjust your standard DSCR underwriting:

Use Current Rents, Not Projections

Lenders won't credit future rent increases from an unfinished transit station. Underwrite the DSCR based on today's achievable rents. The appreciation and rent growth are your bonus, not your baseline.

Factor in Construction-Phase Risks

• Budget for potential vacancy during noisy construction periods
• Consider that appraisals may be conservative during active construction
• Plan for 3-6 months of reserves beyond standard lender requirements

Model Two Scenarios

Run your numbers twice:

1. Base case: Current rents, current conditions, no infrastructure premium
2. Upside case: 10-20% rent increase post-completion, 5-15% appreciation

If the base case produces a DSCR of 1.15+ and the upside case makes the investment compelling, you have a deal worth pursuing.

Consider Short-Term Rental Potential During Construction

In markets near major construction projects, furnished rentals for construction workers and project managers can command 30-50% premiums over standard long-term rents. Some DSCR lenders now accept documented short-term rental income for qualification. Check local STR regulations first.

Case Study: Sound Transit Link Expansion in Seattle

When Sound Transit opened the Northgate Link Extension in 2021, properties within 0.5 miles of the three new stations (Northgate, Roosevelt, U District) saw:

• Rents: 8-12% increase within 18 months of station opening
• Property values: 15-22% appreciation compared to similar properties beyond the transit shed
• Vacancy rates: Dropped from 5.2% to 3.1% in the immediate station area

An investor who purchased a duplex near the Roosevelt station in 2019 for $750,000 (before the station opened) could have seen the property appraise at $900,000+ by 2023. With a DSCR loan at 75% LTV, that $150,000 in appreciation creates significant refinance potential.

The same dynamic is playing out now along the planned Ballard, West Seattle, and Tacoma extensions, with completion dates in the 2030s. Properties near these future stations are still priced without a full transit premium.

Risk Factors to Underwrite

Infrastructure plays aren't guaranteed. Account for these risks:

• Project delays: Major transit projects are delayed an average of 2-3 years. Highway projects average 1-2 years of delays. Your hold period needs to accommodate this.
• Cost overruns that change scope: If a project is scaled back (fewer stations, narrower highway), the impact on your area may be reduced.
• Gentrification resistance: Some communities resist development near new transit, leading to restrictive zoning that limits upside.
• Interest rate changes: If you're counting on refinancing in 3-5 years, model scenarios where rates are 1-2% higher than today.
• Construction nuisance: Lawsuits, noise complaints, and environmental reviews can halt projects for months or years.

How to Research Infrastructure Projects in Your Target Market

Federal sources:

• USAspending.gov: Search for infrastructure grants by location
• BIL.gov: Infrastructure Investment and Jobs Act project tracker
• FTA Capital Investment Grants dashboard: Tracks major transit projects

State and local sources:

• State DOT websites publish 5-year transportation improvement programs (STIPs)
• Metropolitan Planning Organization (MPO) long-range transportation plans
• Local transit agency capital improvement programs

What to look for:

• Projects with federal funding already obligated (not just authorized)
• Environmental review completed (Record of Decision issued)
• Construction contracts awarded
• Active groundbreaking or visible construction activity

These milestones reduce cancellation risk significantly.

FAQ

How soon before a project completes should I buy?

The best returns come from buying 2-4 years before completion, after federal funding is confirmed but before the market fully prices in the improvement. For transit projects, buying after groundbreaking but before station opening tends to balance risk and reward.

Do DSCR lenders give credit for nearby infrastructure projects?

Not directly. Lenders use current appraised values and current achievable rents. However, appraisers may note infrastructure projects as a positive market factor, which can support the value conclusion. The real benefit comes when you refinance after the project completes and values have increased.

What if the project gets delayed or canceled?

This is the primary risk. Mitigate it by only investing near projects with federal funding obligated, environmental clearance obtained, and construction contracts awarded. Even with delays, the investment should work on its own merits at current rents and conditions.

Can I use construction worker rental demand to qualify for a DSCR loan?

If you're renting to construction workers on standard leases (12+ months), that income qualifies like any other rental income. For shorter-term or furnished rentals, some DSCR lenders accept documented STR income, but you'll need to verify local regulations and lender policies.

Which is better for DSCR investing—highway projects or transit projects?

Transit projects typically create more concentrated appreciation (strong premiums within 0.5 miles of stations) but affect a smaller geographic area. Highway projects create broader but more diffuse benefits. Transit is better for targeted, higher-upside plays. Highway access improvements work well for suburban single-family rentals.

How do I account for infrastructure in my property management plan?

During construction, expect higher maintenance costs (dust, vibration, potential water/utility disruptions) and budget accordingly. Post-completion, shift marketing to emphasize transit access or highway convenience. Properties near completed transit can command $100-$200/month more in rent when listings highlight "5-minute walk to light rail."

The Bottom Line

Infrastructure spending is the most predictable catalyst in real estate. Unlike speculative bets on neighborhood trends or market timing, you can literally look at a federal project tracker and see where billions of dollars are flowing. Buy near these projects while prices reflect current conditions, hold through construction, and refinance or sell after completion when values and rents have adjusted upward.

The best DSCR investments near infrastructure projects work even without the infrastructure premium. They cash flow on day one at current rents. The infrastructure is the kicker—not the thesis. That's how you invest with confidence instead of hope.
