3 Home-Buying Mistakes That Could Cost You Thousands
By Sean Zanganeh
Are you ready to buy your next home but worried about making a costly mistake? You're absolutely right to be concerned—the home-buying process is filled with potential pitfalls that can cost you thousands of dollars and months of stress.
Don't worry, because I've got you covered. After over 15 years in San Diego real estate, I've seen buyers make the same expensive mistakes over and over again. Today, I'll share the top three buyer mistakes that could derail your purchase and, more importantly, how to avoid them completely.
From skipping crucial inspections to working with multiple agents and using outdated paperwork, these seemingly small oversights can have massive financial consequences. The good news? Once you know what to avoid, you can save thousands and keep your home-buying journey stress-free.
Don't let these mistakes catch you off guard—let's dive into what every smart buyer needs to know.
Mistake #1: Skimping on Inspections - The $20,000+ Gamble
The Mistake: Many buyers try to save a few hundred dollars by skipping inspections or only getting a basic general inspection, thinking they can spot major issues themselves.
The Reality: This is the most expensive mistake you can make as a homebuyer, potentially costing you tens of thousands of dollars in unexpected repairs.
Why This Happens
In San Diego's competitive market, some buyers feel pressure to:
- Make their offers more attractive by waiving inspection contingencies
- Save money upfront by limiting inspection scope
- Rush through the process to beat other buyers
- Assume that expensive homes don't have hidden problems
This thinking can be catastrophic.
The True Cost of Skipping Inspections
What Inspections Actually Cost in San Diego:
- General home inspection: $300-$600 for average homes
- Specialty inspections: $100-$500 each
- Total comprehensive inspection package: $800-$1,500
What Hidden Problems Can Cost:
- Foundation issues: $10,000-$40,000+
- Electrical system problems: $5,000-$15,000
- Plumbing line replacements: $3,000-$12,000
- Roof replacement: $15,000-$30,000
- HVAC system replacement: $8,000-$20,000
- Mold remediation: $5,000-$25,000
Essential Inspections You Need
1. General Home Inspection Cost: $300-$600 Covers: Structure, electrical, plumbing, HVAC, roof, and major systems
2. Pest/Termite Inspection Cost: $100-$300 Critical in San Diego's climate where termites and other pests are common
3. Sewer Line Inspection Cost: $200-$400 Essential for older homes or properties with large trees nearby
4. Pool/Spa Inspection Cost: $150-$300 Required by law in California for properties with pools
5. Specialty Inspections When Needed:
- Mold testing: $300-$600
- Structural engineering: $500-$1,500
- Electrical panel upgrade assessment: $200-$500
Real San Diego Example
A client of mine recently saved $18,000 by investing $1,200 in comprehensive inspections. The general inspection revealed what appeared to be a minor water stain in the bathroom ceiling. A follow-up mold inspection discovered extensive hidden water damage and mold behind the walls. The seller agreed to remediate the issue rather than lose the sale, saving my client a massive post-purchase surprise.
How to Approach Inspections Smartly
Start with the Essentials:
- Always get a general inspection—no exceptions
- Add pest inspection (often required by lenders anyway)
- Include sewer line inspection for homes over 20 years old
Follow Your Inspector's Recommendations: If your general inspector recommends specialty inspections, get them. They're seeing something that concerns them.
Budget Appropriately: Plan for $1,000-$1,500 in inspection costs for a typical San Diego home. This represents less than 0.2% of a $700,000 purchase—minimal insurance against major problems.
Time Them Right: Schedule inspections as soon as your offer is accepted. Most inspection contingencies in San Diego last 7-17 days, and you'll want time to address any issues discovered.
Mistake #2: Working with Multiple Agents - The Loyalty Problem
The Mistake: Some buyers think they'll get better service or find more properties by working with multiple real estate agents simultaneously.
The Reality: This approach almost always backfires, creating confusion, ethical issues, and potentially costing you the home you want.
Why Buyers Make This Mistake
Common (Flawed) Reasoning:
- "More agents means more properties to see"
- "I can compare their services and choose the best one"
- "It gives me more negotiating power"
- "I don't want to commit until I know who's best"
What Actually Happens:
- Agents stop working hard for you because they know you're not committed
- You see the same properties multiple times through different agents
- Confusion about who represents you in offers
- Potential legal and ethical complications
- Missed opportunities because no agent is fully invested in your success
The Real Problems This Creates
1. Divided Attention When agents know you're working with others, you become a lower priority. They focus their energy on committed clients who will actually close transactions with them.
2. Missed Market Intelligence Agents share their best off-market opportunities and insider knowledge with loyal clients, not with people they're competing against other agents to serve.
3. Offer Complications In San Diego's competitive market, you need an agent who knows your situation inside and out and can craft compelling offers quickly. Multiple agents can't provide this level of personalized service.
4. Ethical Issues If you submit offers through different agents, you could face legal complications and damage your reputation with listing agents.
The Smart Approach: Choose One Great Agent
How to Select the Right Agent from the Start:
Interview 2-3 Agents Maximum
- Ask specific questions about their experience and approach
- Request references from recent buyers
- Discuss their knowledge of your target neighborhoods
- Understand their communication style and availability
Key Questions to Ask:
- How many transactions did you close last year?
- What's your average days on market for buyer clients?
- How do you help buyers compete in multiple offer situations?
- What's your approach to pricing strategy and negotiations?
- How quickly do you respond to new listings?
Red Flags to Avoid:
- Agents who pressure you to sign immediately
- Those who can't provide recent buyer references
- Agents unfamiliar with your target price range or neighborhoods
- Anyone who doesn't explain the buyer representation agreement clearly
The Buyer Representation Agreement: Your Protection
Why It Matters:
- Legally establishes your agent's duty to represent your interests
- Clarifies compensation arrangements upfront
- Protects you from conflicts of interest
- Ensures dedicated service throughout your search
What to Negotiate:
- Duration (start with 30-90 days for new relationships)
- Specific services included
- Compensation structure
- Termination clauses if you're not satisfied
Benefits of Agent Loyalty
When you commit to one excellent agent, you get:
- Priority access to new listings and off-market properties
- Personalized market insights and neighborhood expertise
- Stronger relationships with listing agents
- More compelling offers backed by agent reputation
- Dedicated attention throughout your entire search
Mistake #3: Outdated Paperwork - The Deal Killer
The Mistake: Using old pre-approval letters, outdated financial documents, or expired insurance quotes when making offers.
The Reality: In San Diego's fast-moving market, outdated paperwork can immediately disqualify your offer, regardless of how strong it might be otherwise.
Why This Happens
Common Scenarios:
- Buyers get pre-approved months ago and assume it's still valid
- Using financial documents from previous home searches
- Not updating employment or income information
- Forgetting to refresh insurance estimates
- Assuming market conditions haven't changed
The Stakes Are High: In a market where homes receive multiple offers, sellers and listing agents scrutinize every detail. Outdated paperwork signals that you're either not serious or not prepared—both deal killers.
Critical Documents That Expire Quickly
1. Pre-Approval Letters
- Typical validity: 60-90 days
- Why they expire: Interest rates, employment status, and debt levels change
- Update frequency: Every 60 days during active searching
2. Bank Statements
- Acceptable age: Usually within 30-60 days
- Why freshness matters: Lenders need current asset verification
- What to update: All account statements, especially checking and savings
3. Employment Verification
- Refresh timeline: Every 30 days for active searches
- Critical changes: Job changes, salary adjustments, bonus payments
- Documentation needed: Recent pay stubs, employment letters
4. Insurance Quotes
- Validity period: 30-60 days typically
- Why they matter: Required for loan approval and closing
- Market factors: Rates change frequently, especially in fire-prone areas
The San Diego Market Reality
Why Timing Matters More Here:
- Average time from offer to closing: 30-45 days
- Multiple offers are common (homes receive 4 offers on average)
- Listing agents can afford to be picky about buyer qualifications
- Cash offers often compete against financed purchases
What Listing Agents Look For:
- Recent pre-approval letters (within 30 days preferred)
- Strong financial documentation
- Quick closing timelines
- Minimal contingencies
How to Stay Current
Monthly Tasks During Active Searching:

- Update bank statements and financial documents

- Check insurance quotes and coverage options

Real Consequences of Outdated Paperwork
Case Study: A buyer in La Jolla lost their dream home because their pre-approval letter was 75 days old. Even though they were fully qualified and offered $20,000 over asking price, the listing agent chose another offer with current documentation. The winning buyer offered $10,000 less but had paperwork dated within the previous week.
Common Results:
- Offers rejected without consideration
- Requests for updated documents delay negotiations
- Loss of credibility with listing agents
- Missed opportunities in fast-moving markets
