10 Mortgage Mistakes California Buyers Make (And How to Avoid Them)

I've seen California buyers lose their dream homes, waste thousands, or get stuck with terrible loans -- all from avoidable mistakes.

After 15 years and hundreds of transactions, here are the 10 biggest errors I see. I'm Bill McCoy (CA DRE #01212512). Learn from others' pain.

1. Shopping for Homes Before Getting Pre-Approved

You fall in love with a $750K home, then find out you qualify for $600K. Or you find the perfect place, make an offer, and lose it to a buyer who was already pre-approved. Get pre-approved BEFORE you start shopping.

2. Ignoring Your Credit Until You Apply

A client got pre-approved at 6.5%. Underwriter found a $2,500 collection. Score dropped 40 points. New rate: 7.25%. That's $200/month extra for 30 years = $72,000. Check credit 3-6 months before buying. Fix errors. Pay off collections.

3. Financing a Car During the Mortgage Process

A client financed a $50K Tesla 2 weeks before closing. DTI went from 42% to 49%. Loan denied. Lost the house plus $15K in deposits and inspection costs. Don't change anything financial between pre-approval and closing. No new credit. No big purchases. No job changes.

Broker's Tip: Lenders pull credit again 3 days before closing. They will catch new debt.

4. Draining Your Savings for the Down Payment

A buyer used every penny for 20% down. Week after move-in, roof leaked. No money for repairs. Ended up selling 8 months later at a loss. Keep 3-6 months of expenses in savings AFTER closing.

5. Not Shopping Multiple Lenders

A client got a big bank quote: 6.75% + $6,000 fees. Came to me: 6.25% + $3,000 fees. That's $250/month + $3K upfront = $93K over 30 years. Get quotes from 2-3 lenders. Compare rates AND fees.

6. Choosing the Lowest Rate Without Understanding Costs

Lender A: 6.0% with $12,000 in fees. Lender B: 6.25% with $4,000 in fees. Break-even is 5+ years. If you sell in 3 years, Lender B was cheaper. Compare APR, which includes fees in the calculation.

7. Waiving Contingencies to Win a Bidding War

A buyer waived the appraisal contingency on a $900K home. It appraised at $850K. The lender wouldn't lend on $900K. Buyer had to bring $50K extra cash or lose a $25K deposit. Only waive contingencies if you have cash reserves to cover worst-case scenarios.

8. Overestimating Rental Income on Investment Properties

Zillow says rent is $3,500. But after vacancy, repairs, management fees, and turnover costs: $3,500 rent - $3,800 expenses = -$300/month. Use conservative estimates and run real numbers before buying.

9. Not Reading Loan Documents

A client signed an ARM thinking it was fixed. Year 6, rate adjusted from 4% to 7%. Payment jumped $800/month. Had to sell. Read the Loan Estimate and Closing Disclosure carefully. Ask questions.

10. Believing "Rent is Throwing Money Away"

A client bought a $650K SF condo. Mortgage + HOA + taxes + insurance = $4,650/month. Could've rented the same unit for $3,200. After 3 years, sold for $640K. Lost $62K compared to renting. Run the rent vs. buy math honestly.

Bonus Mistakes

• Lying on your application = mortgage fraud. Felony. Don't.
• Ignoring property taxes. California prop tax = 1.25% of purchase price annually.
• Skipping the home inspection. $500 inspection can save $50K in repairs.
• Not understanding PMI. Less than 20% down means $200-$400/month in PMI.
• Forgetting HOA fees. $300/month HOA = $108K over 30 years.
