The $147,000 Question: What Waiting to Buy Actually Costs Greater Boston Homebuyers
Rent payments, missed appreciation, and rate uncertainty add up faster than you think. Here's the math on why 'waiting for the right time' might be the most expensive decision you make.
Every month you wait costs money—but how much? We modeled the true cost of delaying a home purchase in Greater Boston across multiple scenarios: rent paid, appreciation missed, and rate environments. The result: waiting 2 years in a typical scenario costs $147,000+.
The Setup: Why This Analysis Matters
- "I'm waiting for rates to drop."
- "Prices have to come down eventually."
- "I'll save more and buy next year."
These feel like prudent strategies. But they carry hidden costs that compound faster than most buyers realize.
This analysis models the true cost of waiting—including the scenarios where waiting actually makes sense.
Data Sources: Federal Reserve Economic Data (FRED), Massachusetts Association of Realtors (MAR), Zillow Home Value Index, U.S. Census Bureau American Community Survey, and Greater Boston rental market data.
📊The Three Costs of Waiting
Every month you delay a home purchase, three costs accumulate:
1. Rent Payments (100% Sunk Cost)
Rent builds zero equity. Every dollar paid is gone forever.
2. Missed Appreciation
If prices rise while you wait, you pay more later—or get priced out entirely.
3. Rate Uncertainty
Waiting for lower rates is a bet. Rates might drop—or they might not. And if prices rise while you wait, rate drops may not offset the higher purchase price.
🧮The Math: A Realistic Scenario
Let's model a typical Greater Boston buyer:
- Starting Point (January 2026):
- Target home price: $900,000
- Current rent: $3,500/month
- Mortgage rate: 6.5%
- Down payment saved: $180,000 (20%)
The Question: What happens if this buyer waits 2 years?
📈Scenario A: "Rates Drop But Prices Rise"
This is the most likely scenario based on historical patterns and Greater Boston's structural undersupply.
- Assumptions:
- Rates drop to 5.5% (1 percentage point decline)
- Prices rise 4%/year (conservative, below 10-year average)
- Rent continues at $3,500/month
| Cost Category | 2-Year Impact | Notes |
|---|---|---|
Rent Paid | $84,000 | 24 months × $3,500 = 100% sunk cost |
Price Increase | $74,880 | $900K × 8.16% compounded = $973,440 new price |
Monthly Payment Difference | -$312/mo | Lower rate partially offsets higher price |
Net Cost of Waiting | $147,380 | Rent + price increase - rate benefit |
The Rate Drop Didn't Save You
Why? The rate benefit ($312/month savings × 360 months = ~$112K lifetime savings) is more than offset by:
- $84,000 in rent paid
- $73,440 higher purchase price
- Larger down payment needed ($194,688 vs $180,000)
The insight: Rate drops only help if prices don't rise faster than rates fall.
📉Scenario B: "Rates Stay Flat, Prices Rise"
What if rates don't drop at all?
- Assumptions:
- Rates stay at 6.5%
- Prices rise 4%/year
- Rent continues at $3,500/month
| Cost Category | 2-Year Impact | Notes |
|---|---|---|
Rent Paid | $84,000 | 24 months × $3,500 |
Price Increase | $74,880 | $900K → $973,440 |
Rate Benefit | $0 | No rate change |
Net Cost of Waiting | $158,880 | Pure opportunity cost |
Without even a rate drop to partially offset the damage, waiting costs nearly $160,000 in this scenario.
🎯Scenario C: "The Buyer's Dream" (When Waiting Wins)
For waiting to be the right choice, you need a specific combination of events:
- Assumptions:
- Rates drop to 5.0% (1.5 point decline)
- Prices stay flat (0% appreciation)
- Rent continues at $3,500/month
| Cost Category | 2-Year Impact | Notes |
|---|---|---|
Rent Paid | $84,000 | 24 months × $3,500 |
Price Change | $0 | Flat prices |
Monthly Payment Savings | $468/mo | 6.5% → 5.0% on $720K loan |
Lifetime Rate Savings | $168,480 | $468 × 360 months |
Net Benefit of Waiting | $84,480 | Rate savings - rent paid |
When Waiting Makes Sense
1. Rates drop significantly (1.5+ percentage points)
2. Prices stay flat or decline (rare in Greater Boston)
3. Your rent is relatively low (reduces sunk cost)
4. You can actually save more during the wait period
The problem: In Greater Boston's structurally undersupplied market, flat prices are historically unlikely. The region hasn't seen a meaningful price decline since 2009-2011.

📚Historical Context: What Actually Happens
Let's look at what actually happened to buyers who waited in past rate environments:
2018-2019: "Rates Are Too High"
In late 2018, 30-year rates hit 4.94%. Many buyers paused, waiting for relief.
- What happened:
- Rates did drop (to 3.7% by late 2019)
- But Greater Boston prices rose 5.2% during that period
- Buyers who waited paid more—even with lower rates
2022-2023: "The Rate Shock"
When rates spiked from 3% to 7%+ in 2022, transaction volume cratered.
- What happened:
- Prices barely budged (down ~2% peak-to-trough in Greater Boston)
- Sellers simply didn't sell—inventory tightened further
- Buyers who waited didn't get price relief; they just paid high rates on slightly lower prices
2024-2025: "Waiting for Normalization"
Rates stabilized around 6.5%. Many buyers stayed on the sidelines.
- What happened:
- Greater Boston prices rose 4.1% (2024) and 3.8% (2025)
- A $850K home in Jan 2024 became a $920K home by Jan 2026
- Buyers who waited are now competing for the same homes at higher prices
The Pattern
- Prices are "sticky" downward — sellers wait rather than discount
- Rate drops trigger demand surges — competition returns before prices adjust
- Waiting rarely produces the expected outcome — the "perfect moment" doesn't arrive

🤔The Hidden Costs Beyond Dollars
The financial math is only part of the story. Waiting also carries lifestyle costs that don't show up in spreadsheets:
1. Housing Insecurity
- Renters face:
- Lease non-renewals
- Landlord decisions to sell
- Rent increases (averaging 4-6% annually in Greater Boston)
- Restrictions on modifications, pets, and lifestyle choices
2. School District Uncertainty
- Families with children can't:
- Commit to a school district
- Build community ties
- Plan around school schedules and extracurriculars
3. Wealth Building Delay
- Every year you rent is a year you're not:
- Building equity
- Benefiting from appreciation
- Creating forced savings through mortgage payments
- Establishing roots in a community
4. Psychological Cost
The stress of perpetual house hunting—losing bidding wars, watching dream homes slip away, feeling "stuck"—takes a real toll that's hard to quantify.
⚖️When Waiting IS the Right Choice
Waiting makes sense in specific circumstances:
You're Not Financially Ready
- Emergency fund < 6 months expenses
- Down payment < 10% (ideally 20%)
- Debt-to-income > 43%
- Job instability or pending career change
You're Not Geographically Committed
- Likely to relocate within 3-5 years
- Career requires flexibility
- Life circumstances are uncertain
You're Buying in a Declining Market
- Local economic fundamentals are weakening
- Population is declining
- Major employer is leaving
- (Note: This does NOT describe Greater Boston)
You're Targeting a Specific Event
- Waiting for a specific bonus or inheritance
- Timing around a life event (wedding, graduation)
- Building a larger down payment with a clear timeline
When Waiting Is NOT the Right Choice
- You're financially ready but hoping for "better" prices
- You're trying to "time the market"
- You're waiting for rates to hit some arbitrary target
- You've been outbid and are taking a "break" out of frustration
- You're paralyzed by analysis paralysis
The uncomfortable truth: In a structurally undersupplied market, the biggest risk isn't overpaying slightly—it's failing to secure durable housing at all.
🧭Reframe the Question
Instead of asking:
> "Will prices fall?" or "Will rates drop?"
Ask:
> "What would have to happen for waiting to be the right choice?"
Then honestly assess how likely that scenario is.
- In Greater Boston, you'd need:
- Significant rate drops (1.5%+)
- Flat or declining prices (historically rare)
- Your rent to be low enough that the sunk cost is manageable
If that combination seems unlikely—and historically it has been—then the math favors buying sooner rather than later.
🔧Practical Steps: Make the Decision
Step 1: Calculate Your Personal Breakeven
Use our Rent vs Buy Calculator to model your specific scenario:
- Your actual rent
- Your target price point
- Your down payment
- Your expected time horizon
Step 2: Define Your "Wait" Assumptions
If you're going to wait, be specific:
- What rate are you waiting for?
- What price decline do you expect?
- How long are you willing to wait?
- What will you do if your assumptions don't materialize?
Step 3: Stress Test Your Assumptions
Ask:
- What if rates don't drop?
- What if prices rise 5% instead of falling?
- What if rent increases during your wait?
- What if you're priced out of your target neighborhoods?
Step 4: Consider the Non-Financial Factors
- How important is housing stability?
- How much is the stress of renting costing you?
- What opportunities are you missing by not being settled?

Open Rent vs Buy Calculator🎯The Bottom Line
Waiting to buy feels prudent. But in Greater Boston's undersupplied market, the costs compound faster than most buyers realize:
- Rent payments are 100% sunk cost
- Appreciation continues regardless of your participation
- Rate drops may not offset price increases
- The "perfect moment" rarely arrives
The question isn't whether prices or rates will be "better" someday.
The question is whether you can afford to pay rent, miss appreciation, and bear uncertainty while you wait—and what you're giving up in housing security and wealth building during that time.
For most financially ready buyers in Greater Boston, the math favors action over waiting.
Informed buyers make calmer decisions. Now you have the math to make yours.
Key Takeaways
2. Rate drops don't guarantee savings — If prices rise faster than rates fall, you're worse off
3. Greater Boston is undersupplied — Structural constraints mean prices are unlikely to fall meaningfully
4. Historical patterns favor buyers — Waiting strategies have rarely worked in Greater Boston over the past decade
5. Non-financial costs matter — Housing security, community roots, and wealth building all compound
6. Define your assumptions — If you're waiting, know exactly what you're waiting for
7. The real question — Can you afford the cost of waiting while you hope for a better market?
