Homebuying Myths That Can Cost You Real Money

The 20% figure comes from a time when conventional loans carried stricter requirements and private mortgage insurance (PMI) — a monthly premium added when a buyer puts down less than 20% — was less common. Today, Federal Housing Administration (FHA) loans allow down payments as low as 3.5% for borrowers with qualifying credit scores. Some conventional loan programs backed by Fannie Mae and Freddie Mac permit as little as 3% down. VA loans (for eligible veterans and service members) and USDA loans (for qualifying rural properties) may require no down payment at all.

The trade-off is real: lower down payments typically mean higher monthly payments and the added cost of PMI until sufficient equity is built. But the myth that 20% is a requirement has caused many buyers to delay unnecessarily — sometimes for years.

Ownership builds equity over time, but it also comes with property taxes, insurance, maintenance, HOA fees in many communities, and closing costs on both ends of a transaction. When the total cost of ownership is compared honestly to renting in a given market, renting often makes more financial sense — particularly for people who may relocate within a few years.

The break-even horizon (the point at which buying outpaces renting financially) varies widely by city, neighborhood, and individual circumstances. In high-cost markets, that horizon can stretch to five, seven, or even ten or more years. For a nuanced look at what renting actually involves, see common myths about renting that can cost you.

Pre-qualification is typically based on self-reported income, assets, and debt — it gives a rough sense of borrowing range but involves no verification. Pre-approval requires a lender to review pay stubs, tax returns, bank statements, and credit history, resulting in a conditional commitment to lend up to a specific amount.

In competitive markets, many sellers and their agents will not seriously consider an offer without a pre-approval letter. Arriving with only a pre-qualification can signal to sellers that a deal may not close smoothly — a meaningful disadvantage when multiple offers are in play.

Closing costs alone — which include lender fees, title insurance, appraisal, escrow, and prepaid expenses — typically range from 2% to 5% of the loan amount. On a $350,000 home, that's $7,000 to $17,500 due at closing in addition to the down payment. Property taxes, homeowner's insurance, and potential HOA dues are recurring annual costs that can meaningfully affect affordability.

Buyers focused only on the purchase price or monthly mortgage payment can find themselves stretched thin once the full cost picture becomes clear. Building a realistic budget that accounts for all of these factors before making an offer is essential.

During particularly competitive markets, some buyers waive inspection contingencies to make their offers more attractive. While this may help win a bidding war, it removes a key safeguard. A professional home inspection can surface structural issues, faulty wiring, plumbing problems, roof damage, or environmental hazards — defects that could cost thousands or tens of thousands of dollars to address.

Some buyers opt for a pre-offer inspection (conducted before submitting an offer, with the seller's permission) as an alternative — keeping their offer clean while still gaining material knowledge about the property's condition.

Lenders use credit scores to price risk. A borrower with a score in the mid-600s may be offered a substantially higher interest rate than a borrower with a score above 760 — even on the same loan amount. On a 30-year fixed mortgage, that difference in rate can compound to a significant sum over time.

Before applying for a mortgage, it is worth reviewing your credit reports for errors, paying down revolving balances where possible, and avoiding new credit applications. Even modest improvements to a credit score in the months before applying can influence the terms a lender offers.
