Short answer: budget for closing costs (roughly 2–5% of the purchase price), a few thousand dollars for moving and immediate repairs, and a separate emergency fund of 3–6 months of expenses that you do not touch to make the deal work. On a median-priced U.S. home, that's realistically another $25,000–$40,000 on top of your down payment — and if that number just made your stomach drop, good, better now than at the closing table.

The down payment gets all the attention because it's the number that determines whether you qualify for the loan. But it's not the number that determines whether you can actually afford to own the house. That second number is quieter, less discussed, and the thing that actually wrecks new homeowners.

Closing costs: the bill nobody warns you about loudly enough

Closing costs are the fees for actually processing the loan and transferring the property — lender fees, title insurance, appraisal, recording fees, prepaid property taxes and homeowners insurance, and so on. Bankrate and LendingTree both put the typical range at 2% to 5–6% of the loan amount, though it varies a lot by state, loan type, and lender (as of August 2026).

A 2025 industry report from LodeStar, cited by Bankrate, put the average purchase-transaction closing cost at $4,661 for a single-family home — but the spread by state is enormous, from around $1,551 in South Dakota to $17,545 in Washington, D.C. Translation: "closing costs" is not a fixed number, it's a regional tax on the entire transaction, and you need to ask your lender for a real Loan Estimate early, not guess from a national average.

Since the national median existing-home price hit $434,100 in July 2026 (NAR), a buyer at 3% closing costs on that home is looking at roughly $13,000 — due at the closing table, in addition to the down payment, usually as a cashier's check or wire, not a Venmo request you can stall on.

Moving costs: small line item, real money

Nobody budgets for the actual move because it feels like an afterthought compared to a six-figure mortgage. It isn't free. Local moves with professional movers run roughly $301 to $3,512 depending on home size and hours billed; long-distance/interstate moves run $2,509 to $11,641 (moveBuddha, updated August 2026). Even a DIY move with a rented truck and a case of beer for your friends isn't zero — gas, truck rental, and boxes add up to a few hundred dollars minimum.

The day-one reserve: repairs, furniture, and the stuff that isn't optional

Inspection reports find things. Even a house that passes clean tends to reveal something within the first few weeks — a water heater that's louder than it should be, a garage door opener that finally gives up, blinds for windows that came bare. Buyers on r/FirstTimeHomeBuyer consistently describe getting hit with a major system replacement — HVAC, plumbing, an appliance — in the first three to six months of ownership, even when everything worked fine for the previous owner. Systems don't know they've changed hands; they just know they're old.

Set aside a few thousand dollars specifically for "stuff that breaks or is missing in month one" — separate from your ongoing maintenance budget below. This isn't optional cushion, it's closer to a known cost you just don't have an invoice for yet.

The 1% rule for ongoing maintenance

The most commonly cited rule of thumb, used across the industry and echoed constantly in first-time-buyer threads, is to budget 1% of your home's value per year for maintenance and repairs — separate from your mortgage payment. On the median $434,100 home, that's roughly $4,340 a year, or about $360 a month, that needs to exist somewhere in your budget beyond principal, interest, taxes, and insurance (PITI).

Fannie Mae's own guidance is more nuanced: closer to 1% for a newer home, climbing toward 4% for a home 30+ years old, since older homes need more roof, HVAC, and plumbing replacements. If you're buying a 1960s house with the original everything, budgeting like it's a 2022 build is how you end up surprised. This isn't a fund you build up once and forget — it's a recurring line item, like a subscription you didn't ask for but definitely have.

The emergency fund: separate from all of the above

This is the part people skip because they've already stretched to hit the down payment and closing costs, and there's nothing left. That's exactly the problem. Multiple sources — Experian summarizing guidance from major banks and FINRA, and general personal-finance consensus — recommend keeping 3 to 6 months of expenses in reserve after closing, untouched by the home purchase itself (Experian, citing Wells Fargo, FINRA, and others). The CFPB doesn't set a hard number and instead suggests thinking about your own history of unexpected expenses — reasonable advice, less satisfying than a clean rule.

Lean toward the higher end (5–6 months) if you're a single-income household, have variable income, or work in an industry that's had layoffs recently. Lean toward 3 if you have strong job security and other liquid backup (a HELOC you could tap, family who could help in a real emergency, etc.). The point isn't the exact number — it's that this money is not the same pool as your down payment or your maintenance fund. If your "emergency fund" doubles as your closing-cost cushion, you don't have one.

Putting your own number together

Here's the rough math, using the July 2026 median home price of $434,100 and typical assumptions:

  • Down payment (20%): $86,820 — not part of this article's number, but shown for scale
  • Closing costs (3%): ~$13,000
  • Moving costs: ~$1,500 (local, modest move)
  • Day-one repair/furnishing reserve: ~$2,500
  • Emergency fund (4 months of a $4,000/month household budget): ~$16,000

That's roughly $33,000 beyond the down payment — before your first annual maintenance budget of ~$4,300 even kicks in. Your own number will move based on your home price, your local closing costs, your move distance, and your actual monthly expenses, but the framework doesn't change: down payment, closing costs, moving, immediate reserve, ongoing maintenance, and a genuinely separate emergency fund are six different buckets, not one big pile of "house money."

None of this means you need six figures sitting around to buy a house responsibly — plenty of buyers put 3.5% down and use the difference for exactly these reserves instead of maximizing their down payment, and that's a legitimate strategy, not a consolation prize. The mistake isn't buying with less down; it's not knowing these other buckets exist until the invoice shows up.
