Buying a home in 2026 is a genuinely different experience than it was even a decade ago. Prices have climbed, mortgage rates have resettled into a new range, and the rules that once guided buyers through the process have quietly become unreliable. The problem is that outdated advice tends to stick around long after it stops being useful.
Much of what gets passed down from parents, friends, and well-meaning coworkers was true at some point, but the housing market has shifted enough that following the wrong guidance can cost you real money or delay homeownership unnecessarily. Here are eleven pieces of conventional wisdom that deserve a hard second look.
1. You Absolutely Need a 20% Down Payment
According to NerdWallet’s 2025 Home Buyer Report, nearly two thirds of Americans still believe that a 20% down payment is required to buy a home. That belief is simply not accurate. Since roughly a third of non-homeowners say that not having enough money for a down payment is holding them back, this misconception could be stopping people unnecessarily.
Advice from older generations is often to aim for 20%, but mortgage products like FHA loans, which permit down payments of 3.5%, and VA and USDA loans, which permit as little as zero down, can open the door to homeownership for those who don’t have a large sum of cash available. The median down payment is currently 18% for all buyers and 9% for first-time buyers, according to the National Association of Realtors.
2. Wait for Mortgage Rates to Drop Before You Buy
Perhaps the most expensive mistake homebuyers make is sitting on the sidelines, convinced that mortgage rates will inevitably decline to even lower levels. While rates remain elevated compared to the rock-bottom levels of 2020 and 2021, waiting for a dramatic drop could backfire in multiple ways. If mortgage rates do decline, buyers will likely face increased competition from others who were also waiting, which could drive up home prices and negate any savings from the lower rate.
Waiting for rates to drop may be a losing game, since a decline may motivate a large number of other buyers to start searching too. Based on available analysis, waiting for a modest rate drop may not pay off quickly enough to justify delaying a home purchase, with data suggesting that only rate cuts of roughly 0.6 percentage points or more offer meaningful savings within a reasonable timeframe.
3. Renting Is Always Throwing Money Away
This one gets repeated so often it feels like gospel. The reality is more nuanced. While renting can be cheaper short-term in some markets, buyers do build equity and gain stability with fixed payments over time. With rents rising faster than inflation in many areas, monthly mortgage payments can actually end up lower than rent in certain markets.
In today’s market, buyers should think medium to long term. With the costs of rent so far below the costs of buying in many markets, today’s home shoppers face a much longer break-even horizon, meaning that buying typically only becomes the better financial decision if the buyer plans to stay in the home for more than seven years. Renting strategically while building savings isn’t a failure. It can be a smart financial move depending on where you live and how long you plan to stay.
4. You Need Perfect Credit to Get a Mortgage
A myth that follows many buyers into the mortgage process is the belief that only those with flawless credit scores can get approved for a loan. This can be intimidating enough to stop some people from even exploring their options. In reality, different loan programs are designed to support buyers with a wide range of credit histories.
Lenders look at the full picture of a financial profile, not just a single number. That includes income, debt, savings, and overall financial stability. Your credit score matters, but it’s just one part of a much larger story. For example, FHA loans require a minimum score of 580 for the buyer to be eligible for a smaller down payment. Many people with imperfect credit have bought homes and done just fine.
5. Skip the Home Inspection to Win the Offer
During the most frenzied stretches of the pandemic housing boom, buyers were waiving inspections just to compete. That pressure has eased considerably. Skipping the inspection is risky. Inspections uncover hidden problems that aren’t obvious during a showing, such as faulty wiring, roof damage, and foundation problems. Without one, you’re buying the home as-is, including costly issues the seller might not disclose. The few hundred dollars saved on the inspection could cost thousands down the road.
A licensed home inspector may uncover damage or issues with the house that buyers should be aware of before owning the property. If an inspection does find significant damage, buyers may be able to negotiate with the seller to repair the issues, negotiate a lower asking price, or walk away if they have an inspection contingency. A smarter move in competitive situations is to shorten contingency timelines, offer higher earnest money, or get pre-underwritten financing.
6. Your Pre-Approval Amount Is Your Budget
Getting pre-approved feels like a milestone, and it is. But confusing the maximum loan amount you qualify for with what you can actually afford comfortably is a costly mistake. A pre-approval amount represents the maximum a lender thinks you can borrow, not the amount you can comfortably afford. Stretching your budget to its limit is risky. Monthly housing costs could consume a massive chunk of your income, leaving little for savings, emergencies, or other spending.
Lenders assess whether you can technically make the payment, not whether you’ll be comfortable doing it for thirty years. Your grocery bills, car payments, childcare costs, and retirement contributions don’t factor into that calculation. Most financial advisors suggest not buying a home if the monthly payment would exceed roughly a quarter of your take-home pay, because any more than that risks leaving too little money for other important financial goals.
7. Property Taxes Stay the Same After You Buy
First-time buyers often fixate on the mortgage payment and treat property taxes almost as an afterthought. That can be a painful oversight. With the rapid increase in home prices during and after the pandemic, property taxes have increased at a faster-than-usual rate. According to data analytics firm CoreLogic, the average property tax bill in the U.S. increased by roughly a quarter between 2019 and 2024. Since home prices are forecast to continue increasing, buyers can expect higher tax bills in the future as well.
In many states, property assessments are recalculated periodically, and a newly sold home often triggers a reassessment at its sale price. If you plan on moving to another county or state, you need to research local property tax rates and be prepared for potentially higher costs. A real estate agent can provide information on current tax rates in the area, or you can look it up through public resources. Running the real numbers on taxes before closing protects you from an unpleasant first-year surprise.
8. Only First-Time Buyers Qualify for Assistance Programs
This assumption causes a significant number of buyers to stop looking for help before they’ve even started. Many down payment assistance programs have broader eligibility than people realize. Many down payment assistance programs offer financial help to buyers making down payments and covering closing costs, and these programs are often available on the local, state, and federal levels. Grants don’t require repayment, making them an especially attractive option.
Repeat homebuyers may still qualify for certain down payment assistance programs. Income limits, location requirements, and property type often matter more than whether you’ve owned before. For those who find saving for a large down payment challenging, certain loan programs can help make homeownership more accessible, including VA loans and USDA loans which aren’t required to make a down payment at all. It’s worth checking what’s available before assuming you don’t qualify.
9. Always Choose the Lowest Mortgage Rate You Can Find
It seems obvious that the lowest rate wins. In practice, it’s more complicated than that. Choosing a mortgage based on the lowest rate alone is not always the best option. A mortgage decision involves many moving parts, including loan terms, closing costs, monthly payments, upfront fees, and how long you plan to stay in the home. A slightly lower rate might come with higher expenses elsewhere, while a loan with a slightly higher rate may better align with your financial goals.
Buyers should also evaluate the annual percentage rate, which incorporates both the interest rate and the fees, giving a more accurate picture of the loan’s true cost. Sometimes accepting a slightly higher rate with lower closing costs will keep more money in your pocket for emergencies, renovations, or other investments. The rate is the headline, but the full loan package is what really determines what you pay.
10. Closing Costs Are Just a Small Extra Fee
Underestimating closing costs is one of the most common financial shocks in the homebuying process. Buyers who’ve saved diligently for a down payment can be caught completely off guard when they see the closing disclosure. Even if you’re not putting down 20%, a down payment isn’t the only upfront cost to save for. You’ll need to account for additional expenses like closing costs, agent fees, inspections, and moving costs.
For example, with a median sale price for a single-family home in late 2025 around $435,000, average closing costs could range from roughly $8,700 to $21,700. Agent fees could add several thousand dollars more on top. Sometimes the seller may cover a portion of closing costs, but that is not guaranteed. Planning for closing costs as a distinct line item, not a rounding error, makes the entire process far less stressful.
11. Homeowners Insurance Is a Fixed, Predictable Cost
Buyers who bake a modest homeowners insurance estimate into their monthly budget and never revisit it are in for a rude awakening over time. Insurance premiums have been rising sharply and show little sign of slowing down. The increasing frequency and severity of weather-related events in recent years have led to rapidly rising insurance costs. Annual premiums have increased by more than sixty percent since 2019 and hit a record high in 2024. Costs are likely to keep rising, and in some markets obtaining an insurance policy at any price has become difficult.
Some of the largest insurance companies in the country, including Farmers, Allstate, and State Farm, are limiting their exposure in climate-risky states like California and Florida. Buyers should consider the availability and cost of homeowners insurance in the market where they’re looking to buy. In some regions, the cost of insuring a home is now one of the most significant financial variables in the entire buying decision, and it deserves the same attention as the mortgage rate itself.
The housing market has changed enough in recent years that advice which once felt like common sense can now quietly work against buyers. Revisiting these assumptions before making one of the largest financial decisions of your life isn’t just smart. It’s essential.
