Putting 20% down on a $300,000 house means writing a check for $60,000. At this price point you are looking at a starter home in many parts of the country, and for first-time buyers especially, $60,000 can feel like a mountain. The good news is that a $300K home is well within the range of low-down-payment programs, and the monthly payment difference between 3% and 20% down is manageable enough that either approach can work depending on your situation.
Down Payment Amounts on a $300K House
| Down Payment % | Amount | Loan Amount | PMI Required? |
|---|---|---|---|
| 3% | $9,000 | $291,000 | Yes |
| 5% | $15,000 | $285,000 | Yes |
| 10% | $30,000 | $270,000 | Yes |
| 15% | $45,000 | $255,000 | Yes |
| 20% | $60,000 | $240,000 | No |
| 25% | $75,000 | $225,000 | No |
A $300K home is right at the entry-level price in most metros. In the Midwest and South, this buys a solid 3-bedroom single-family home. In expensive coastal markets, it is more likely a condo or townhouse. Either way, $9,000 to $60,000 is the cash range you’re planning for.
Notice that the jump from 3% to 5% down is only $6,000 more cash but gives you slightly better loan terms and a wider selection of lenders willing to work with you. If you can swing 5%, it is usually worth the small extra savings.
How Down Payment Affects Your Monthly Mortgage
At 6.5% interest on a 30-year fixed mortgage:
| Down Payment | Loan Amount | P&I Payment | PMI (~0.5%) | Total Payment |
|---|---|---|---|---|
| 3% ($9,000) | $291,000 | $1,839 | $121 | $1,960 |
| 5% ($15,000) | $285,000 | $1,801 | $119 | $1,920 |
| 10% ($30,000) | $270,000 | $1,706 | $113 | $1,819 |
| 20% ($60,000) | $240,000 | $1,516 | $0 | $1,516 |
Note: PMI is estimated at 0.5% annually. Actual rates vary by credit score and lender.
Putting 20% down saves $404/month compared to 3% down (before taxes and insurance).
At this price point, the monthly savings from 20% down are meaningful but not dramatic — roughly $400/month. Your total monthly housing cost including property taxes (~$3,500-$6,000/yr depending on your state) and homeowners insurance (~$1,200-$2,400/yr) will run $1,900-$2,500 with 20% down or $2,300-$2,900 with 3% down.
For most households earning $60,000-$90,000 per year, both ends of that range are within the standard 28% front-end debt-to-income ratio that lenders look for. That makes a $300K home one of the most accessible price points for buyers who want flexibility in how much they put down.
What PMI Costs on a $300K Home
PMI on a $300K house with 5% down typically runs $80-$150 per month depending on your credit score. Borrowers with excellent credit (740+) pay toward the lower end, while scores in the 620-680 range may see premiums closer to $150.
At $119/month, PMI adds $1,428 per year to your housing costs. Over the 7-9 years it typically takes to reach 20% equity through payments alone, that totals $10,000-$13,000. That sounds like a lot, but compare it to the alternative: waiting 3-5 extra years to save the full $60,000. If rents in your area are $1,200-$1,500/month, those extra years of renting cost $43,200-$90,000 — and you build zero equity during that time.
Under the Homeowners Protection Act, your lender must automatically cancel PMI once your loan balance reaches 78% of the original purchase price. You can also request early removal once you hit the 80% mark. If your home appreciates, a new appraisal can get you there faster.
Total Interest Paid Over Loan Life
| Down Payment | Loan Amount | Total Interest (30-yr, 6.5%) |
|---|---|---|
| 5% ($15,000) | $285,000 | $363,200 |
| 10% ($30,000) | $270,000 | $344,100 |
| 20% ($60,000) | $240,000 | $305,800 |
20% down saves $57,400 in interest compared to 5% down.
That $57,400 assumes you keep the loan for the full 30 years. Most homeowners move or refinance within 7-13 years, so the realistic interest savings are closer to $20,000-$35,000. Still worthwhile, but the gap narrows when you consider a shorter holding period.
If you are buying a starter home and plan to upgrade within 5-7 years, the interest savings from a larger down payment may not be worth delaying your purchase — especially if home prices in your area are rising. Building equity through appreciation and principal paydown can outweigh the interest savings from a bigger down payment.
How Long to Save $60,000 for 20% Down
| Monthly Savings | Time to $60,000 |
|---|---|
| $500/month | 10 years |
| $1,000/month | 5 years |
| $1,500/month | 3.3 years |
| $2,000/month | 2.5 years |
| $2,500/month | 2 years |
Parking your savings in a high-yield savings account earning 4-5% APY shortens these timelines by a few months. At $1,000/month with 4.5% interest, you hit $60,000 in about 4.5 years instead of 5.
The real question is whether waiting makes sense in your market. If homes are appreciating at 4% per year, a $300,000 house today costs $312,000 next year and $349,000 in five years. Your target down payment amount keeps growing, and you miss out on the equity you would have been building.
What Income Do You Need for a $300K House?
| Down Payment | Est. Monthly Housing Cost | Income Needed (28% rule) |
|---|---|---|
| 3% ($9,000) | ~$2,500 | ~$107,100/yr |
| 5% ($15,000) | ~$2,460 | ~$105,400/yr |
| 10% ($30,000) | ~$2,340 | ~$100,300/yr |
| 20% ($60,000) | ~$2,060 | ~$88,300/yr |
These figures include estimated property taxes and homeowners insurance. Your actual requirements may be lower if you have minimal other debts, since many lenders approve up to 43-45% total debt-to-income. A household earning $75,000 with no car payment or student loans could potentially qualify for a $300K purchase even with just 5% down.
Closing Costs Add Up
Your down payment is not the only cash you need. Closing costs on a $300K home typically range from $6,000 to $12,000 (2-4% of the purchase price). These cover appraisal fees, title insurance, attorney fees, lender origination charges, and prepaid items like homeowners insurance and property tax escrow.
With 20% down, plan for $66,000-$72,000 in total cash at closing. With 5% down, it is $21,000-$27,000. In both cases, make sure you keep a separate emergency fund — draining all your savings to buy a house leaves you vulnerable to unexpected repairs, medical bills, or job loss right when you have a new mortgage payment to cover.
Some sellers will agree to cover part of your closing costs (seller concessions), which can reduce the cash you need. FHA loans allow sellers to contribute up to 6% of the purchase price toward your closing costs.
Down Payment Assistance for First-Time Buyers
A $300K home falls squarely in the range targeted by most down payment assistance programs:
- FHA loans: 3.5% down ($10,500) with a credit score of 580+. Widely available and the most common path for first-time buyers with limited savings.
- Conventional 97: 3% down ($9,000) for first-time buyers through Fannie Mae or Freddie Mac. Requires 620+ credit score.
- VA loans: 0% down for eligible veterans and active-duty service members. No PMI required.
- USDA loans: 0% down for properties in eligible rural and suburban areas. Income limits apply, but many areas outside major metros qualify.
- State programs: Nearly every state housing finance agency offers grants, forgivable loans, or matched savings programs for first-time buyers. Many cover 3-5% of the purchase price, which at the $300K level means $9,000-$15,000 — potentially your entire down payment.
Should You Put 20% Down on a $300K House?
Put 20% down if you have $60,000 saved beyond your emergency fund and closing costs, you want the lowest possible monthly payment, you are in a slow-appreciation market, or you plan to stay in this home for 10+ years.
Put less than 20% down if you are a first-time buyer and saving $60,000 would take 3+ more years of renting, your market is seeing 4%+ annual price appreciation, you have steady income that comfortably covers the slightly higher payment, or you want to keep cash available for moving costs, furniture, and initial repairs.
Wait to buy if you do not have at least 3-6 months of expenses saved beyond your down payment and closing costs, your debt-to-income ratio is above 43%, or you are unsure you will stay in the area for at least 3-5 years. Selling a home within 2-3 years of buying often results in a net loss after transaction costs.
