Home Purchase Budget: Everything You Need to Save Before You Buy
Planning to buy a home in 2026? Here is exactly how much you need to save — down payment, closing costs, reserves, moving costs, and the hidden expenses most buyers forget until it is too late.
When pulling together a home purchase budget, most home buying guides focus heavily on the monthly mortgage payment and stop there. But the upfront cash requirement to purchase a home is almost always larger than buyers expect — and running short at closing is one of the most stressful situations in real estate. This guide builds a complete home purchase budget from scratch, covering every cost category so there are zero surprises on closing day. Before you start looking at homes, be sure to use an affordability calculator to establish your true home purchase budget based on your income and debts.
The 5 Budget Categories Every Buyer Needs
A comprehensive home purchase budget must account for five distinct buckets of costs. Most buyers only budget for categories 1 and partially 2 — leaving categories 3, 4, and 5 as expensive surprises.
- (1) Down payment
- (2) Closing costs
- (3) Cash reserves
- (4) Moving and immediate costs
- (5) Ongoing monthly costs
Category 1 — Down Payment
Your down payment is the most significant upfront cost. Here is the range of down payment options and their total cash requirements on homes priced from $250,000 to $500,000:
| Home Price | 3% Down | 10% Down | 20% Down |
|---|---|---|---|
| $250,000 | $7,500 | $25,000 | $50,000 |
| $350,000 | $10,500 | $35,000 | $70,000 |
| $400,000 | $12,000 | $40,000 | $80,000 |
| $500,000 | $15,000 | $50,000 | $100,000 |
Note that putting less than 20% down triggers Private Mortgage Insurance (PMI) — adding $100–$400/month to your ongoing costs. Check our full down payment guide for an analysis of which down payment percentage makes sense for different financial situations.
Category 2 — Closing Costs
Closing costs are paid on top of the down payment and typically run 2–5% of the purchase price. For a $350,000 home, that means $7,000–$17,500 in additional cash due at closing. The major components include lender fees, title insurance, appraisal, attorney fees, prepaid taxes, and upfront insurance premiums. Stress that these are non-negotiable minimums — you cannot close without paying them. In some cases, sellers can be negotiated to cover a portion as a concession. See our comprehensive closing costs breakdown for the full itemised list.
Category 3 — Cash Reserves
Most lenders require borrowers to have 2–6 months of mortgage payments remaining in savings after closing. According to the Consumer Financial Protection Bureau, this is not money you spend — it is money you must demonstrate you have. On a $2,500/month mortgage, a lender requiring 3 months of reserves wants to see $7,500 untouched in your account at closing.
Beyond lender requirements, financial advisors recommend keeping a separate home emergency fund of 1–3% of the home value for unexpected repairs. On a $350,000 home, that is $3,500–$10,500 in accessible savings. Here is a combined reserves table:
| Home Price | 3 Month Reserves ($2,500/mo) | 1% Emergency Fund | Total Reserves |
|---|---|---|---|
| $250,000 | $7,500 | $2,500 | $10,000 |
| $350,000 | $7,500 | $3,500 | $11,000 |
| $500,000 | $7,500 | $5,000 | $12,500 |
Category 4 — Moving and Immediate Costs
These are the costs most buyers completely forget to budget for:
- Moving costs: $1,000–$5,000 for a local move, $5,000–$15,000 for long distance.
- Immediate repairs and upgrades: even move-in ready homes often need paint, new locks, cleaning, and minor repairs — budget $1,500–$5,000.
- New appliances: if the home does not include a washer, dryer, or refrigerator, budget $1,500–$4,000.
- Window treatments and basic furniture: $1,000–$5,000 depending on the home size.
- Utility deposits and connection fees: $200–$500 across electricity, gas, water, and internet.
Total realistic immediate costs run from $5,000–$20,000 depending on the home condition and distance of the move.
Category 5 — Ongoing Monthly Costs
To truly understand how much house you can afford, you must build a complete monthly budget for homeownership beyond the mortgage payment. Here is a realistic example for a $350,000 home with 10% down at 6.8%:
| Monthly Cost | Amount |
|---|---|
| Principal and interest | $2,059 |
| Property tax (escrow) | $321 |
| Homeowners insurance | $120 |
| PMI (under 20% down) | $131 |
| HOA fees (if applicable) | $0–$500 |
| Maintenance (1%/yr rule) | $292 |
| Utilities (estimate) | $250–$400 |
| Total | $3,173–$3,823 |
Conclude: the true monthly cost of homeownership is typically $500–$1,000 higher than the mortgage payment alone. Plan your budget around the full number. Find out exactly how your mortgage payment is calculated and get escrow accounts explained to avoid surprises. First-time buyers can also check with HUD for assistance programs.
Your Complete Home Purchase Budget: A Summary
Let's pull it all together in one table for a $350,000 home with 10% down:
| Budget Category | Low Estimate | High Estimate |
|---|---|---|
| Down payment (10%) | $35,000 | $35,000 |
| Closing costs (2–5%) | $7,000 | $17,500 |
| Cash reserves | $7,500 | $11,000 |
| Moving and immediate | $5,000 | $20,000 |
| Total upfront needed | $54,500 | $83,500 |
Conclude: for a $350,000 home with 10% down, plan to have between $55,000 and $85,000 in accessible savings — not $35,000. This is the number most buyers do not know until it is too late.

Frequently Asked Questions
How much money do I need to buy a $350,000 house?

What are the upfront costs of buying a home?
The main upfront costs include your down payment (typically 3% to 20%), closing costs (2% to 5% of the purchase price), upfront home inspection and appraisal fees, plus moving expenses and any immediate home repairs needed before you settle in.
