A mortgage is often the biggest financial commitment of your life, so even small mistakes can end up costing thousands of dollars over time. Many homebuyers focus on finding the right property but overlook the details of their mortgage, which can quietly increase expenses. The good news? With awareness and planning, you can avoid common pitfalls and keep your mortgage as affordable as possible.
Your credit score directly impacts the interest rate you qualify for. A low score could mean higher rates and, ultimately, a more expensive loan. Many buyers rush into applying without
first reviewing their credit report.
How to avoid it: Check your credit score months before applying. Pay down debts, fix errors, and avoid taking on new credit. Even modest improvements can save thousands in interest over the life of the loan.
While some loan programs allow low or no down payments, putting down too little increases the loan amount and monthly payments. It can also trigger private mortgage insurance (PMI), which adds to costs.
How to avoid it: Aim to save as much as possible for a down payment. If you can manage 20%, you’ll avoid PMI and reduce long-term expenses. If 20% isn’t realistic, try to reach at least 10% to balance affordability and cost savings.
Many buyers simply go with the first lender they talk to, assuming mortgage rates and fees are the same everywhere. This can lead to paying higher interest rates or unnecessary fees.
How to avoid it: Request quotes from at least three lenders. Compare not only interest
rates but also closing costs, fees, and loan terms. Sometimes, the lowest rate isn’t the
cheapest option overall.
Government-backed loans like FHA, VA, and USDA mortgages can save eligible buyers money. Unfortunately, some homebuyers don’t take the time to explore these programs.
How to avoid it: Research available loan options. If you’re a first-time buyer, veteran, or purchasing in a rural area, you may qualify for more affordable programs with lower down payment requirements.
Homebuyers often focus on the down payment and monthly mortgage but forget that closing costs can add 2–5% of the purchase price. Rolling these into your loan increases the total balance and interest paid.
How to avoid it: Budget early for closing costs. Ask lenders for a Loan Estimate to understand all upfront expenses and explore if any fees can be negotiated.
Mortgage rates can fluctuate daily. If you don’t lock in your rate, you could end up paying more than expected by the time you close.
How to avoid it: Once you find favorable terms, ask your lender about a rate lock to secure it during the loan process.
