Most Buyers Ask the Wrong Question
The question sounds simple: how much money do you really need to buy a home? Ask ten people and you’ll get ten answers, because most of them are answering a different question than the one that decides anything. They’ll talk about the down payment. They’ll quote the old 20% rule. What they skip is the number that actually determines whether your offer gets accepted, your loan closes, and you still have money in the bank the week after you get the keys.
That number is your total cash to close, plus whatever you need left over afterward. Here’s how to find yours, built up one piece at a time.
Step 1: Split Your Money Into Four Buckets
Every dollar you need falls into one of four categories. Lenders only care about the first two. Your future self cares about all four.
- Down payment — the percentage of the purchase price you pay up front.
- Closing costs — lender fees, title insurance, appraisal, prepaid taxes and insurance. Usually 2% to 5% of the loan amount.
- Cash reserves — money still sitting in your account after closing. Many lenders want to see two months of mortgage payments left over.
- Move-in costs — movers, utility deposits, a fridge, blinds, and that first trip to the hardware store.
Step 2: Run the Numbers on a $375,000 House
Let’s use a $375,000 purchase price with 10% down. Round numbers, nothing exotic.
Down payment: $37,500
Ten percent is a comfortable middle ground. It keeps your loan below most jumbo thresholds and it’s enough to convince a seller you’re serious. Put down less than 20% and private mortgage insurance comes along with the deal.
Closing costs: $8,000 to $12,000
On a $337,500 loan, budget roughly 2.5% to 3.5% of the loan amount. That covers the origination fee, the appraisal (typically $600 to $800), title search and lender’s title insurance, recording fees, and the escrow cushion of two or three months of property taxes and homeowner’s insurance collected up front. Transfer taxes vary wildly by state and can add several thousand on their own.
Cash reserves: about $5,500
Say your total monthly payment lands at $2,740 for principal, interest, taxes and insurance. Two months of that is $5,480. Lenders want it in the bank after closing, not spent on a sectional sofa.
Move-in costs: $2,000 to $6,000
A local move runs $1,000 to $2,500. Long distance can hit five figures. Add deposits for utilities and a few hundred for the stuff you won’t realise you need until night one.
Total: roughly $53,000 to $60,000 for a $375,000 house. Not $75,000. Not $37,500. Somewhere in between, depending on your state, your lender, and your timing.
Step 3: Work Backwards From What You Have
Now flip the calculation. Say you have $45,000 saved and you want $8,000 still in the bank after closing. That leaves $37,000 to cover the down payment, closing costs, and moving. If closing costs run about 2.5% of the price and your down payment is 10%, then:
0.125 × price = $34,000 (setting aside $3,000 for moving)
Price ≈ $272,000.
That’s your ceiling, not the $400,000 a lender might pre-approve you for. A pre-approval tells you what a bank will lend. It says nothing about what you should spend. If you’re still working out the savings side of this, our guide on how much you should realistically save before buying a home is the right place to start, because the answer shifts a lot depending on whether you’re six months out or three years out.
Step 4: Know Where the Cheap Down Payments Are
You don’t have to bring 20%. Here’s what the main loan programs actually require.
- Conventional: as little as 3% down for first-time buyers, 5% otherwise. PMI applies until you reach roughly 20% equity.
- FHA: 3.5% down with a 580+ score, 10% with a 500–579 score. Comes with an upfront mortgage insurance premium plus an annual one.
- VA: 0% down for eligible veterans and surviving spouses, plus a funding fee some borrowers can have waived.
- USDA: 0% down in eligible rural areas, with an upfront and annual guarantee fee.
A smaller down payment lowers your cash to close and raises your monthly payment. There’s no free lunch here, just a trade you get to choose.
Step 5: The One Variable That Moves Everything
Your credit score sets your interest rate, and your rate sets your monthly payment. On a $337,500 loan, the gap between a 640 score and a 760 score can exceed a full percentage point, which is more than $200 a month on the exact same house. It nudges your homeowner’s insurance premium in most states too.
If your score needs work, a step-by-step plan to move your credit score from 620 to 760 before you shop will do more for your budget than any negotiation at the closing table. Fixing a score takes four to six months. Fixing a rate after closing takes a refinance.
Step 6: Build the Money in the Right Order
- 12 months out: Set your target using the four-bucket method above. Then stop guessing and get a real pre-approval. The home buying process from pre-approval to closing day runs in a set order, and skipping steps is expensive.
- 9 months out: Pay down revolving debt and open zero new credit lines. No store card for the new couch.
- 6 months out: Park savings somewhere you can’t casually spend it. Every stray dollar goes into that account.
- 3 months out: Get fully underwritten rather than just pre-qualified, lock your rate, and don’t shuffle money between accounts without a paper trail.
Timing matters as well. When rates dip and inventory is thin, waiting for a perfect market can cost more than buying in a merely good one. It’s worth weighing whether now is the right time to buy a house against your own lease dates and savings timeline rather than the headlines.
What to Do If You’re Short
Being $10,000 short isn’t a dead end. These options genuinely work:
- Seller concessions. Ask the seller to cover closing costs in exchange for a slightly higher price. You don’t pay less overall, but you keep your cash.
- Down payment assistance. State housing finance agencies and many cities run first-time buyer programs, often structured as a forgivable second mortgage.
- Gift funds. Family contributions are allowed on most loans. They need a gift letter and a clean paper trail.
- Lender credits. Accept a slightly higher rate and the lender absorbs part of your closing costs. Run it both ways before deciding.
- Buy less house. Unglamorous and the option that saves the most. One buyer bought a Florida home $55,000 under asking simply by being patient and willing to walk away.
The Test That Tells You You’re Ready
Forget the calculators for a second. You’re ready to buy when three things are true at once. Your full cash-to-close sits in an account you can access within a week. You’ll still have three months of mortgage payments left after the movers leave. And your total housing payment, taxes, insurance and HOA dues included, lands under 30% of your take-home pay.
Miss one of those and the house isn’t the problem. The timing is. Wait a few months, fix the piece that’s off, and come back with a number you don’t have to stretch for.
And plan for the overage. Appraisals come in low, escrow shortages happen, and moving trucks cost more in July. Aim for the top of your range instead of the middle, and the closing table will feel a lot less like a cliff edge.
