Putting 20% down on a house is often ideal to avoid Private Mortgage Insurance (PMI), secure a lower interest rate, and have smaller monthly payments, but it's not always necessary or feasible; you can buy with less (even 0-5%) by accepting PMI, though it adds cost, or you might invest the difference if market conditions favor it and you maintain emergency funds. The best choice depends on your financial situation, risk tolerance, and local market, balancing saving for a larger down payment against the costs (rent, missed equity) of waiting.
Key Takeaways
Putting down at least 20% on a house is the wisest move—it keeps you from paying private mortgage insurance (PMI) and saves you thousands in interest over time. If you're a first-time home buyer, a 5–10% down payment is okay—but be ready for a higher monthly payment with PMI tacked on.
If you're applying for a conventional mortgage with less than 20% down, your lender may require that you purchase private mortgage insurance. Typically, most homebuyers wrap the premium for the insurance into their monthly mortgage payment.
As a rule of thumb, buy-and-hold real estate investors normally make a down payment of around 20-25% when financing an investment property, although some loan programs offer investment property financing with down payments as low as 15%.
A Bigger Down Payment Signals Financial Stability
Sellers want to avoid deals falling through. A buyer putting down 3% is often seen as riskier than one putting down 20%. A larger down payment suggests the buyer is financially solid—and less likely to get denied by the lender at the last minute.
The 3-7-3 Rule in mortgages isn't a loan type but a federal timeline from the TILA-RESPA Integrated Disclosure (TRID) rule, ensuring borrower protection by mandating disclosures within 3 business days of application, a 7-business-day wait between the initial Loan Estimate and closing, and another 3-day wait if significant changes (like APR) occur, giving borrowers time to review costs before committing to a loan.
Strategies to Avoid the 20% Down Payment
Contrary to popular belief, a 20% down payment is not a mandatory requirement for purchasing a home, as numerous loan programs, including FHA, VA, and USDA options, allow for significantly lower or even 0% down payments for qualified individuals.
Cons of Saving for a 20% Mortgage Down Payment
The benefits of paying half down on a house are quite clear, as you can significantly reduce your monthly mortgage payments. You'll have less to pay every month and have more money in your pocket for other expenses. You'll be paying less on the mortgage's interest if you pay 50% up front.
To afford a $700,000 house, you generally need an annual income between $180,000 to $235,000, depending on interest rates, down payment, and existing debts, with lenders often using the 28/36 rule (housing costs under 28% of gross income, total debt under 36%) to assess affordability. A 20% down payment ($140,000) is common, reducing your loan, but taxes, insurance, and other expenses add to the total monthly cost.
With a $150,000 salary, you could afford a home priced around $415,000-$430,000, assuming you have $20,000 saved up for a down payment and are carrying some monthly debt already, such as a car payment or student loan. This also assumes an interest rate of 7%.
To pay off a 30-year mortgage in 10 years, you must aggressively pay down the principal with strategies like increasing monthly payments significantly, making bi-weekly payments (effectively one extra payment yearly), applying lump sums from bonuses/refunds, and potentially refinancing to a shorter-term loan, all while ensuring extra funds go directly to the principal to save thousands in interest.
A household should allocate no more than 28% of their gross income to housing expenses. Total debt payments, including housing, should not exceed 36% of gross income under the 28/36 rule. Lenders often use the 28/36 rule to evaluate creditworthiness and loan approval.
The Rule prohibits the lender and consumer from closing or settling on the mortgage loan transaction until 7 business days after the delivery or mailing of the TILA disclosures, including the Good Faith Estimate and disclosure of the final Annual Percentage Rate (APR), even when all parties are prepared and desire to ...
In other words, if you put down less than 20 percent, it will add a bit more to your monthly payments in the form of PMI. The exact amount depends on how much you did put down and what your interest rate is. Fortunately, PMI will not usually extend for the entire life of a conventional loan.
