Common mortgage mistakes to avoid

John Cronin

According to a 2023 study by the Consumer Financial Protection Bureau (CFPB), nearly 30% of borrowers regret their mortgage decisions due to preventable mistakes.


Whether you're a first-time homebuyer or a seasoned investor, understanding these common mortgage mistakes can save you thousands of dollars and prevent unnecessary stress. In this comprehensive guide, we'll break down the top 5 mortgage mistakes, how to avoid them, and why working with a trusted lender like Austin Capital Mortgage ensures a smooth homebuying journey.


1. Not Shopping Around for a Mortgage


Why It’s a Problem


Many borrowers accept the first mortgage offer they receive, often from their bank or a single lender. However, interest rates and fees can vary significantly between lenders.


  • A 2022 Freddie Mac report found that borrowers who compare at least 3 lenders save $1,500+ on average over the life of their loan.
  • Some lenders charge higher origination fees or have stricter underwriting requirements.


How to Avoid This Mistake

  • Get rate quotes from 3-5 lenders (including banks, credit unions, and mortgage brokers).
  • Compare APR (Annual Percentage Rate) instead of just interest rates—it includes fees.
  • Ask about discount points and lender credits.


2. Skipping Mortgage Pre-Approval


Why It’s a Problem


pre-approval letter is a lender’s commitment to finance your home up to a certain amount. Without it:


  • Sellers may ignore your offer in competitive markets.
  • You might fall in love with homes outside your budget.
  • Delays in financing can cause missed opportunities.


How to Avoid This Mistake

  • Get pre-approved before house hunting.
  • Provide complete financial documentation (W-2s, tax returns, bank statements).
  • Ensure your pre-approval is underwritten, not just pre-qualified.


3. Choosing the Wrong Type of Mortgage


Why It’s a Problem


Not all mortgages are the same. Picking the wrong loan type can lead to:


  • Payment shock (e.g., adjustable-rate mortgages adjusting higher).
  • Longer loan terms than necessary (costing more in interest).
  • Strict refinancing requirements later.


Common Mortgage Types

Loan Type Best For Risk
Fixed-Rate Buyers staying 7+ years Low (stable payments)
Adjustable-Rate (ARM) Short-term buyers (5-7 years) Moderate (rates can rise)
FHA Loans Lower-credit buyers (580+ FICO) PMI required
VA Loans Veterans/military No down payment needed


How to Avoid This Mistake

  • Discuss your long-term plans with a mortgage advisor.
  • Compare fixed vs. adjustable rates based on how long you’ll stay in the home.
  • Avoid interest-only loans unless you’re an experienced investor.


4. Underestimating Closing Costs


Why It’s a Problem


Many first-time buyers are shocked by closing costs, which average 2-5% of the loan amount ($6,000–$15,000 on a $300,000 home). Common fees include:


  • Loan origination fees (0.5–1% of loan)
  • Appraisal & inspection fees ($500–$1,000)
  • Title insurance & escrow fees ($1,000–$2,500)


How to Avoid This Mistake

  • Ask lenders for a Loan Estimate (LE) within 3 days of applying.
  • Negotiate seller concessions (some sellers cover part of closing costs).
  • Save 3-5% extra beyond your down payment.


5. Taking on New Debt Before Closing


Why It’s a Problem


Lenders recheck your credit before closing. New debt can:


  • Lower your credit score (even a 20-point drop can raise your rate).
  • Increase your debt-to-income ratio (DTI), risking loan denial.
  • Trigger last-minute underwriting delays.


What to Avoid Before Closing


  • Opening new credit cards
  • Financing a car or furniture
  • Making large cash withdrawals (lenders may question funds)


How to Avoid This Mistake

  • Keep credit usage below 30%.
  • Avoid big purchases until after closing.
  • Notify your lender before making financial changes.
