How to Budget for a House: Down Payment, Closing Costs, and Beyond

How much should you save before buying a house?

You should save for four things before buying a house, not one: your down payment, closing costs (typically 2% to 5% of the purchase price and separate from the down payment), moving and setup costs, and an emergency cushion of three to six months of expenses. The down payment is the headline number, but it is rarely the largest share of the real cash you need.

The Consumer Financial Protection Bureau frames the calculation simply: start with your total available savings, subtract anything earmarked for other goals, moving, furnishings, or your emergency fund, and what remains is your true cash available for closing. From there you subtract estimated closing costs to find your maximum down payment. It is worth reading the CFPB's own walkthrough on how much to spend on a home before you settle on a target price.

The piece most first-time buyers underestimate is the cushion. Closing on a house and then having no savings left is how a dream purchase turns into stress by month two. Keep your emergency fund intact as its own pool of money, separate from your home savings, so a surprise repair or income gap doesn't force you back into debt right after you get the keys.

What is a realistic down payment — and do you need 20%?

A 20% down payment is the classic target because it lets you avoid mortgage insurance, but you do not need it to buy: FHA loans allow as little as 3.5% down, and other low-down-payment programs exist. The trade-off is that putting down less than 20% usually adds mortgage insurance to your monthly payment, and a smaller down payment can mean higher total costs over the life of the loan.

So the realistic answer is "as much as you can comfortably reach without draining your cushion." Decide your target home price, decide your down-payment percentage, and turn that into a single dollar figure you are actually saving toward. A vague "save for a house" goal stalls; a specific "$32,000 by next spring" goal moves. Setting that exact number as a tracked goal — and watching the progress bar fill — is the difference between hoping and planning, which is the whole idea behind setting financial goals you can measure.

One more check before you fix the number: affordability. A widely used guideline is the 28/36 rule — try to keep total housing costs near 28% of your gross monthly income and your total debt payments under 36%. It is a guideline, not a law, but if your target home blows past it, that is a signal to adjust the price or the timeline rather than the cushion.

What ongoing costs should your house budget include?

Your house budget should include the costs of owning, not just buying: property taxes, homeowners insurance, mortgage insurance if you put down less than 20%, any HOA dues, utilities, and a maintenance reserve of roughly 1% of the home's value per year. These recurring and irregular costs are what turn an affordable-looking mortgage payment into a tight monthly budget.

The tricky ones are the costs that do not arrive every month. Property taxes and insurance may be paid annually or held in escrow; maintenance is lumpy by nature — nothing for months, then a water heater. The clean way to handle these is a sinking fund: set aside a little each month for a known future expense so the bill is already covered when it lands. Here is how the one-time and ongoing costs break down.

Cost	When it hits	How to budget it
Down payment	One-time, at closing	Financial Goal
Closing costs (2%–5%)	One-time, at closing	Sinking fund
Property taxes & insurance	Annual or escrowed	Sinking fund / recurring bill
Mortgage insurance (if <20% down)	Monthly	Recurring bill
Utilities & HOA dues	Monthly	Recurring bill
Maintenance (~1%/year)	Irregular	Sinking fund

For the full month-to-month framework around these line items — categories, paychecks, and the rhythm of a household budget — the guide on how to make a home budget picks up where this leaves off. And if you are still weighing buying versus building, the cost side of that decision lives in how much it costs to build a house.

How do you track a house budget month to month?

The most reliable way to track a house budget is to give each piece its own home: a Financial Goal for the down payment, sinking funds for closing costs and maintenance, and a clear monthly savings number so you always know whether you are on pace. SenticMoney is built around exactly this, and it does it without ever connecting to your bank.

In SenticMoney, your down payment becomes a Financial Goal with a target amount and date, and the app shows the contribution you need each month to hit it. Closing costs and future maintenance become sinking funds. And because saving for a house competes with every other bill, Runway cash-flow planning — part of the Standard tier ($39/year) — maps your payday-to-payday cash flow and converts it into a daily spending number, so you can see how much you can set aside without coming up short before the next paycheck. The down-payment goal works on the Free tier, which is manual transaction entry only; Runway is the Standard-tier upgrade.

The quiet advantage is privacy. Saving for a house means your full financial picture — income, balances, how close you are to your goal — sits in one place. SenticMoney keeps that on your own device, with no bank login required at any tier, so planning the biggest purchase of your life doesn't mean handing your finances to a third party. It runs natively on Windows and Mac (a signed, notarized .dmg for macOS 12 and later) and supports any budgeting method, so the plan fits how you already think about money rather than forcing a single system on you.
