Mistake 1: Waiving Inspection in Hot Market

The Mistake

You're competing with 8 other offers. Your agent suggests waiving the inspection contingency to make your offer more attractive. You agree, thinking "how bad could it be?"

The Cost

Real Seattle case (2021):

  • Bought: $875,000 house in Ballard
  • Waived: Inspection contingency
  • Discovered after closing:
    • Foundation cracks requiring $35,000 repair
    • Electrical panel needs $8,000 upgrade
    • Roof has 2–3 years left ($20,000 replacement)
    • Total unexpected costs: $63,000

Why It Happens

  • Hot market pressure (2020–2021, spring markets)
  • Fear of losing the home
  • Agent pressure to compete
  • Seller won't accept offers with contingencies
  • Buyer thinks "it looks fine"

How to Avoid It

Option 1: Pre-inspection

  • Hire inspector before making offer ($500–700)
  • Review report before offering
  • Make informed decision about waiving contingency
  • Still risky (limited time, can't access everything)

Option 2: Inspection for information only

  • Include inspection contingency
  • Agree not to ask for repairs
  • Can still walk away if major issues found
  • Protects you while showing commitment

Option 3: Wait for better market

  • Don't buy in peak hot market
  • Wait for fall/winter when contingencies accepted
  • More inventory, less competition

Option 4: Build repair budget

  • If you must waive inspection, budget $20,000–40,000 for repairs
  • Get home warranty ($500–800/year)
  • Have emergency fund beyond reserves

Pro Tip: Never waive sewer scope in Seattle. Sewer line repairs cost $8,000–25,000. Scope costs $300–500. Always worth it.

Warning Signs

  • Agent says "everyone is waiving inspections"
  • Multiple offers on every home you like
  • Homes selling in 3–5 days
  • Prices increasing 10%+ year-over-year
  • You feel rushed to decide

If you see these signs: Consider waiting for market to cool or expand your search to less competitive areas.

Mistake 2: Buying at Maximum Pre-Approval

The Mistake

Lender pre-approves you for $900,000. You buy a $900,000 home. Your monthly payment is $6,500. You're house-poor.

The Cost

Real Seattle case (2022):

  • Income: $180,000/year
  • Pre-approval: $1,000,000
  • Bought: $975,000 home
  • Monthly payment: $7,200
  • Take-home pay: $10,500
  • Housing: 69% of take-home

Consequences:

  • No money for vacations
  • Can't afford to eat out
  • Stopped 401k contributions
  • No emergency fund
  • Stressed about every expense
  • Regrets purchase daily

Why It Happens

  • Lender approval feels like permission
  • "If they'll lend it, I can afford it"
  • Want the nicest home possible
  • Don't calculate true monthly costs
  • Forget about lifestyle expenses

How to Avoid It

Use the 25% rule:

  • Calculate take-home pay (after taxes)
  • Housing should be ≤25% of take-home
  • This leaves room for life, savings, emergencies

Example:

  • Income: $180,000
  • Take-home: ~$126,000/year = $10,500/month
  • Maximum housing: $2,625/month (25%)
  • This suggests $600,000–700,000 home, not $1,000,000

Better approach:

  • Get pre-approved to know maximum
  • Buy 20–30% below that maximum
  • Test the payment for 3 months (save the difference)
  • Make sure you can afford it comfortably

Pro Tip: If you can't save the difference between current rent and future mortgage for 3 months, you can't afford the house.

Mistake 3: Underestimating Closing Costs

The Mistake

You save $82,500 for 10% down payment on $825,000 home. You forget about closing costs. You're $15,000 short at closing.

The Cost

Real Seattle case (2023):

  • Saved: $85,000
  • Down payment: $82,500 (10%)
  • Closing costs: $18,500
  • Total needed: $101,000
  • Shortfall: $16,000

Solutions (all bad):

  • Borrow from 401k (penalties, lost growth)
  • Borrow from family (relationship strain)
  • Put on credit card (high interest)
  • Reduce down payment to 5% (higher payment, PMI)

Why It Happens

  • Focus only on down payment
  • Don't read Loan Estimate carefully
  • Underestimate inspection/appraisal costs
  • Forget about moving expenses
  • No buffer for surprises

How to Avoid It

Budget 2.5–3% of purchase price for closing costs:

  • $825,000 home: $20,625–24,750
  • $600,000 home: $15,000–18,000
  • $1,000,000 home: $25,000–30,000

Get Loan Estimate early:

  • Lender must provide within 3 days of application
  • Review every line item
  • Ask about anything unclear
  • Compare multiple lenders

Add 10% buffer:

  • Closing costs can increase
  • Unexpected repairs after inspection
  • Moving costs higher than expected
  • Immediate home needs (locks, cleaning)

Total cash needed:

  • Down payment
  • Closing costs
  • Moving expenses ($2,000–3,000)
  • Immediate needs ($3,000–5,000)
  • Emergency fund (6 months expenses)

Mistake 4: Skipping Sewer Scope Inspection

The Mistake

You get home inspection but skip sewer scope to save $400. Six months later, sewer line collapses. Repair costs $18,000.

The Cost

Real Seattle case (2024):

  • Skipped: Sewer scope ($400)
  • Discovered: Tree roots in sewer line
  • Emergency repair: $18,000
  • Could have negotiated with seller if caught before closing
  • Net loss: $17,600

Why It Happens

  • Trying to save money
  • Inspector doesn't include it in standard inspection
  • Don't understand Seattle's old sewer infrastructure
  • Seller says "no problems"
  • Home looks fine above ground

Seattle-Specific Issue

Why sewer scopes matter in Seattle:

  • Many homes built 1900–1960 with clay pipes
  • Tree roots infiltrate clay pipes
  • Pipes deteriorate over 60–100 years
  • Repairs cost $8,000–25,000
  • Homeowners insurance doesn't cover

Warning signs:

  • Home built before 1970
  • Large trees near house or street
  • Slow drains throughout house
  • Gurgling sounds in drains
  • Sewer smell in yard

How to Avoid It

Always get sewer scope:

  • Cost: $300–500
  • Takes 30–60 minutes
  • Camera inspects entire line to street
  • Identifies roots, cracks, bellies, offsets

Make it contingency:

  • Include in inspection contingency
  • If issues found, negotiate with seller
  • Options: repair, credit, price reduction, walk away

Budget for it:

  • Include in inspection budget
  • Worth 10x the cost in potential savings
  • Peace of mind for decades

Pro Tip: If sewer scope shows issues, get repair estimate before negotiating. Seller may lowball repair cost.

Mistake 5: Ignoring HOA Red Flags

The Mistake

You buy a condo with $450/month HOA fee. Seems reasonable. Six months later, $12,000 special assessment for roof replacement. Reserve fund was only 15% funded.

The Cost

Real Seattle case (2023):

  • Bought: $650,000 condo in Capitol Hill
  • HOA fee: $450/month
  • Reserve fund: 18% funded (should be 70%+)
  • Special assessment: $12,000 (roof)
  • Second assessment: $8,000 (siding) one year later
  • Total unexpected: $20,000 in 18 months

Why It Happens

  • Don't review HOA documents
  • Focus only on monthly fee amount
  • Don't understand reserve studies
  • Trust seller's disclosure
  • Rush through due diligence

HOA Red Flags

Financial red flags:

  • Reserve fund under 30% funded
  • HOA fees increasing 10%+ annually
  • Recent or pending special assessments
  • Deferred maintenance visible
  • HOA in litigation

Operational red flags:

  • High owner delinquency (>5%)
  • Difficulty getting documents
  • Board turnover/instability
  • Complaints about management
  • Rental restrictions (if you might rent)

How to Avoid It

Review these documents:

  • HOA budget (last 2 years)
  • Reserve study (when last updated?)
  • Meeting minutes (last 6–12 months)
  • Special assessment history
  • CC&Rs (rules and restrictions)
  • Master insurance policy

Key questions to ask:

  • What's reserve fund percentage?
  • When was last reserve study?
  • Any special assessments planned?
  • What major repairs coming up?
  • Any ongoing litigation?
  • What's included in HOA fee?

Calculate true cost:

  • Monthly HOA fee: $450
  • Annual increases (3%): $14/month/year
  • Special assessment risk: $200/month buffer
  • True cost: $650–700/month

Pro Tip: If reserve fund is under 50% funded and building is 20+ years old, expect special assessments within 5 years.

Mistake 6: Not Budgeting for Maintenance

The Mistake

You budget for mortgage, taxes, insurance. That's it. Water heater fails ($2,500). Roof leaks ($4,000). Furnace dies ($8,000). You have no money saved.

The Cost

Real Seattle case (2022):

  • Bought: $750,000 house
  • Budgeted: Mortgage, taxes, insurance only
  • Year 1 repairs:
    • Water heater: $2,200
    • Gutter repair: $800
    • Appliance replacement: $1,500
    • Plumbing leak: $1,200
    • Total: $5,700
  • Had to put on credit card (no savings)

Why It Happens

  • Think "it's been inspected, should be fine"
  • Don't understand 1% rule
  • Compare to renting (landlord paid repairs)
  • Assume everything will last forever
  • No emergency fund

The 1% Rule

Budget 1% of home value annually for maintenance:

  • $750,000 home: $7,500/year = $625/month
  • $500,000 home: $5,000/year = $415/month
  • $1,000,000 home: $10,000/year = $835/month

What this covers:

  • Routine maintenance (HVAC service, gutter cleaning)
  • Minor repairs (leaky faucet, broken appliance)
  • Seasonal needs (furnace filter, yard care)
  • Unexpected issues (water heater, roof leak)

Major system lifespans:

  • Roof: 20–30 years ($15,000–25,000)
  • HVAC: 15–20 years ($8,000–15,000)
  • Water heater: 10–15 years ($1,500–3,000)
  • Appliances: 10–15 years ($500–2,000 each)
  • Paint (exterior): 10–15 years ($8,000–15,000)

How to Avoid It

Set up maintenance fund:

  • Separate savings account
  • Auto-transfer $625/month (for $750,000 home)
  • Don't touch except for home repairs
  • Builds to $7,500 in year 1

PNW-specific maintenance:

  • Gutter cleaning: $150–300 (2x/year)
  • Moss treatment: $200–400/year
  • Pressure washing: $300–600/year
  • Moisture inspection: $200–400/year
  • Sewer line maintenance: $150–300/year

Pro Tip: Even if you don't spend it all, keep saving. When roof needs replacing in year 15, you'll have $112,500 saved.

Mistake 7: Buying Without Emergency Fund

The Mistake

You use every dollar for down payment and closing costs. You have $2,000 left in savings. You lose your job 4 months later. You can't make mortgage payments.

The Cost

Real Seattle case (2023):

  • Bought: $800,000 home
  • Used all savings: $180,000 (down + closing)
  • Emergency fund: $3,000
  • Lost job: Month 4
  • Couldn't make payments: Month 6
  • Forced to sell: Month 8
  • Sold for: $775,000 (market softened)
  • Total loss: $45,000 (sale costs + price drop)

Why It Happens

  • Eager to buy, don't want to wait
  • Think "I won't lose my job"
  • Underestimate importance of buffer
  • Lender doesn't require emergency fund
  • Focus on getting into home, not staying in it

How Much Emergency Fund?

Minimum: 6 months expenses

  • Calculate all monthly costs
  • Multiply by 6
  • Keep in savings AFTER buying

Example:

  • Mortgage: $4,500
  • Taxes/insurance: $850
  • Utilities: $400
  • Food: $800
  • Transportation: $500
  • Other: $500
  • Total: $7,550/month
  • 6-month fund: $45,300

Tech workers: 9–12 months

  • Tech layoffs common (2022–2023)
  • Job search can take 6–9 months
  • RSU income volatile
  • Need larger buffer

How to Avoid It

Don't buy until you have:

  • Down payment
  • Closing costs
  • Moving expenses
  • 6-month emergency fund

If you don't have enough:

  • Save longer before buying
  • Buy less expensive home
  • Put down less (keep more in savings)
  • Consider renting longer

Pro Tip: If choosing between 20% down and emergency fund, choose emergency fund. You can always refinance to remove PMI later.

Mistake 8: Buying in Wrong Neighborhood

The Mistake

You buy based on price alone. You don't research neighborhood. You discover it's loud, unsafe, or far from everything you need.

The Cost

Real Seattle case (2024):

  • Bought: $600,000 house in South Seattle
  • Didn't visit at night or weekends
  • Discovered:
    • Homeless encampment 2 blocks away
    • Frequent car break-ins
    • 45-minute commute (thought it was 25)
    • No walkable amenities
    • Loud traffic noise
  • Sold after 18 months: $590,000
  • Loss: $50,000 (price drop + transaction costs)

Why It Happens

  • Only tour during day on weekdays
  • Focus on house, not neighborhood
  • Trust online research only
  • Don't talk to neighbors
  • Assume "Seattle is safe everywhere"

How to Avoid It

Visit multiple times:

  • Weekday morning (commute time)
  • Weekday evening (after work)
  • Weekend day (neighborhood activity)
  • Weekend night (noise, safety)

Research thoroughly:

Talk to neighbors:

  • Knock on doors
  • Ask about neighborhood
  • What do they like/dislike?
  • Any issues to know about?
  • Would they buy here again?

Check these:

  • Noise levels (traffic, airport, train)
  • Parking availability
  • Street lighting
  • Sidewalk condition
  • Nearby businesses
  • Homeless encampments
  • Graffiti/vandalism

Pro Tip: Drive through neighborhood at 10pm on Friday/Saturday. You'll see the real character.

Mistake 9: Skipping Title Insurance

The Mistake

You decline owner's title insurance to save $1,500. Two years later, someone claims they own part of your property. Legal fees: $25,000.

The Cost

Real Seattle case (2023):

  • Declined: Owner's title insurance ($1,800)
  • Discovered: Easement dispute with neighbor
  • Legal fees: $18,000
  • Property value impact: $30,000
  • Total cost: $48,000
  • Title insurance would have covered it

Why It Happens

  • Trying to save money at closing
  • Don't understand what it protects
  • Think "title search is enough"
  • Lender's policy protects lender, not you
  • Seems like unnecessary expense

What Title Insurance Covers

Common issues:

  • Liens from previous owners
  • Easement disputes
  • Boundary disputes
  • Forged documents
  • Errors in public records
  • Unknown heirs claiming ownership

Cost:

  • One-time premium: $1,000–2,500
  • Based on purchase price
  • Protects you forever
  • Covers legal fees if claim arises

How to Avoid It

Always get owner's title insurance:

  • Required for lender (lender's policy)
  • Optional for you (owner's policy)
  • Owner's policy protects your equity
  • Lender's policy only protects lender

Review preliminary title report:

  • Provided during escrow
  • Shows liens, easements, restrictions
  • Ask about anything unclear
  • Resolve issues before closing

Pro Tip: In Washington, seller typically pays for title insurance. If you're paying, negotiate with seller to cover it.

Mistake 10: Not Understanding Closing Timeline

The Mistake

You give notice to landlord 30 days before expected closing. Closing delays 3 weeks. You're homeless for 3 weeks or pay double rent/mortgage.

The Cost

Real Seattle case (2024):

  • Expected closing: June 1
  • Gave notice: May 1
  • Actual closing: June 22
  • Paid: 22 days double rent ($2,800) + mortgage ($4,500)
  • Extra cost: $5,300
  • Plus stress of temporary housing

Why It Happens

  • Assume closing date is firm
  • Don't understand contingency timelines
  • Appraisal delays (2–3 weeks typical)
  • Lender processing delays
  • Title issues discovered late
  • Seller delays

Seattle Typical Timeline

From offer acceptance to closing: 30–45 days

Week 1–2:

  • Inspection (10 days typical)
  • Inspection response/negotiation
  • Appraisal ordered

Week 2–3:

  • Appraisal completed (2–3 weeks)
  • Loan processing

Week 3–4:

  • Final loan approval (17 days typical)
  • Title work completed
  • Insurance secured

Week 4–5:

  • Final walkthrough (24–48 hours before closing)
  • Closing disclosure review (3 days before closing)
  • Closing day

Common delays:

  • Appraisal takes 3–4 weeks (not 2)
  • Lender requests more documents
  • Title issues discovered
  • Seller not ready to move
  • Repairs not completed

How to Avoid It

Don't give notice until:

  • Appraisal completed and approved
  • Loan fully approved (not just pre-approved)
  • Title cleared
  • 1 week before closing

Build in buffer:

  • If closing June 1, give notice for June 15
  • Negotiate rent-back with seller if needed
  • Have backup plan (hotel, friend's place)

Communicate with landlord:

  • Explain you're buying (uncertain date)
  • Ask about month-to-month option
  • Negotiate flexible move-out date
  • Offer to pay extra for flexibility

Pro Tip: Negotiate a rent-back with seller. They stay 1–2 weeks after closing, giving you buffer to move out of rental.

Summary: Key Takeaways

  • Never waive inspection without pre-inspection or large repair budget ($20,000–40,000)
  • Buy 20–30% below pre-approval to avoid being house-poor
  • Budget 2.5–3% for closing costs plus moving and immediate expenses
  • Always get sewer scope in Seattle ($300–500 can save $18,000)
  • Review HOA documents thoroughly - check reserve fund percentage and special assessment history
  • Budget 1% of home value for annual maintenance ($625/month for $750,000 home)
  • Keep 6-month emergency fund after buying (9–12 months for tech workers)
  • Research neighborhoods thoroughly - visit multiple times at different times
  • Get owner's title insurance - one-time cost protects you forever
  • Don't give notice to landlord until 1 week before closing with all contingencies cleared

  3. Create a checklist of things to verify before closing
  4. Budget conservatively - assume things will cost more and take longer
  5. Ask questions - if something seems unclear, ask your agent or lender
