There is no single number, but you can estimate it quickly: the cash you need to buy a house in 2026 is your down payment plus closing costs plus a cash reserve, and the income you need is whatever keeps your total housing payment within a sane share of your monthly take-home. For a moderately priced home, the all-in upfront cash often lands somewhere between roughly 5% and 25% of the purchase price depending on your loan and market. Below is how to turn that into a real figure for your situation — and you should confirm the exact numbers with a lender before counting on them.
The four upfront costs
- Down payment. The headline number. It can be as low as around 3% on some conventional loans, 3.5% on FHA-style government-backed loans, sometimes 0% on specific programs, or 20% to avoid private mortgage insurance.
- Closing costs. Lender fees, title, appraisal, taxes, and prepaids. These typically run about 2% to 5% of the loan amount.
- Cash reserves. Many lenders want to see a few months of mortgage payments left in the bank after closing. Even when not required, it is wise.
- Moving and setup. Movers, immediate repairs, furniture, and utility deposits add up — budget a realistic cushion.
Estimating your cash on a sample price
These are illustrative ranges on a hypothetical $350,000 home, not a quote. Your real figures depend on your loan, location, and lender.
| Cash item |
Low-down-payment path |
20%-down path |
| Down payment |
~$10,500 (3%) |
~$70,000 (20%) |
| Closing costs (2–5%) |
~$7,000–$17,000 |
~$6,000–$14,000 |
| Reserves (a few months) |

| Mortgage insurance |

usually avoided |
| Approx. cash to close |
~$18,000–$28,000+ |
~$76,000–$84,000+ |
The low-down-payment path needs less cash but usually adds mortgage insurance and a larger loan; the 20% path needs far more cash but lowers the monthly payment. Neither is automatically "right."
How much income you need
Lenders care less about a target salary and more about ratios. Two common guideposts:
- Front-end ratio. Many lenders prefer your housing payment to stay near or below roughly 28% of gross monthly income.
- Back-end ratio (debt-to-income). Total monthly debt payments, including the mortgage, often need to stay under about 36% to 43% depending on the loan program.
If you want to understand the metric lenders lean on most, read what is debt-to-income ratio in 2026. The point is that two people with the same salary can qualify very differently based on existing debt and credit.
How to figure out your number
- Pick a realistic price range for your area, not a national average.
- Choose a down-payment target based on the cash you have and whether you want to avoid mortgage insurance.
- Add 2% to 5% of the loan for closing costs.
- Add a reserve of a few months of the future payment.
- Get pre-approved so a lender confirms the income and credit picture before you shop seriously.
What to skip
- Emptying your emergency fund. A bigger down payment is not worth being one repair away from debt.
- Forgetting ongoing costs. Property taxes, insurance, maintenance, and possible HOA fees are not in the purchase price.
- Assuming 20% is mandatory. It avoids mortgage insurance but is not required for many loans.
- Stretching to the maximum a lender approves. Approval is a ceiling, not a recommendation.
FAQ
Do I always need a 20% down payment?
No. Many loans allow far less, and some specialized programs allow zero down. A 20% down payment mainly helps you avoid private mortgage insurance and lowers your loan size. Verify what your loan options allow.
What are closing costs?
They are the one-time fees to finalize the loan and transfer — lender charges, title, appraisal, taxes, and prepaid items. Expect roughly 2% to 5% of the loan amount, varying by location.
How much income do I need?
There is no fixed salary. Lenders evaluate ratios like your housing cost versus income and your total debt versus income, alongside credit and reserves. Pre-approval gives you a personalized answer.
Should I put down more or keep cash?
It depends. A larger down payment lowers the monthly payment but leaves less liquidity. Keeping a healthy emergency fund usually matters more than squeezing out a bigger down payment.
