How much house can you actually afford?
The gap between what a lender approves and what you can carry, how large a deposit really has to be and what mortgage insurance costs, whether renting or buying wins over your timeframe, what closing costs come to, and the bills that only start once you own the place.
How much house can I afford?
Work backwards from the monthly payment you can carry rather than forwards from the figure a lender will approve, and count property tax, insurance and maintenance inside that payment rather than the mortgage alone.
There is almost always a gap between approved and affordable, and it is not a mistake on anybody’s part — the two are answering different questions. A lender is testing whether you will probably keep repaying them. It does not know that childcare starts next year, that you want to stop working at 60, or that one of you is about to retrain. The approval is a ceiling, and treating a ceiling as a target is how a house ends up owning the household.
The monthly figure has to be the whole monthly figure. Principal and interest is the number quoted; property tax, buildings insurance and any service or association charge are due whether or not anybody mentions them, and maintenance is the one everybody omits. A common planning figure is around 1% of the property’s value a year on upkeep, which does not arrive evenly — it arrives as nothing for three years and then a roof.
The traditional lending guides put housing at roughly 28% of gross income and total debt payments at around 36%, which is a reasonable first read and has the same weakness as every gross-pay rule: gross is not money you have. Run both against take-home pay instead and you get numbers you can check against a bank statement rather than against a payslip.
Then test it before you sign anything. For three months, pay the difference between your current rent and the proposed all-in payment into savings. If those three months were comfortable, the number is real and you have a deposit that is three months larger. If they were not, you have learned it for free, which is the cheapest this lesson is ever available.
How much do I need for a down payment on a house?
Twenty per cent is the figure everybody quotes and it is not a requirement — plenty of mortgages accept far less — but below it you generally pay mortgage insurance, a monthly charge that protects the lender and buys you nothing.
What 20% actually buys is four things at once: no mortgage insurance, usually a better interest rate, a smaller loan to pay interest on, and a cushion of equity so that a dip in prices does not leave you owing more than the place is worth. That is a real list, and it is why the number became folklore.
What it costs is the years spent reaching it. Those are years of rent, in a market that may be moving away from you faster than you are saving. There is no universally correct answer here — the right one depends on prices where you are, on what your rent is doing, and on how stable the next five years look. Anybody who tells you 20% is mandatory is repeating a rule rather than answering your question.
Mortgage insurance is worth understanding rather than fearing, because it is usually not permanent. On most conventional loans it can be removed once your equity passes a threshold, either through repayment or through the property being worth more — which turns it from a life sentence into a fee for starting earlier. Some loan types work differently and carry it for the life of the loan, so it is a question to ask specifically rather than assume.
And the deposit is not the whole cash requirement, which is the thing that catches first-time buyers hardest. Closing costs are due at the same moment, the move itself costs money, and an empty house asks for several things in its first month. A plan that leaves you with nothing on completion day is how people end up putting a boiler on a credit card in their first winter.
Is it better to rent or to buy?
Buying tends to win over a long stay and lose over a short one, because the fees at both ends of the transaction take several years of ownership to earn back.
“Rent is throwing money away” is the sentence that ends most of these conversations early, and it does not survive contact with the numbers. Owning has its own money that never comes back: mortgage interest, property tax, insurance, maintenance and the transaction fees themselves. The honest comparison is unrecoverable cost against unrecoverable cost — rent on one side, all of that on the other — and only the principal you repay is actually building anything.
Which is why the length of stay decides it. Buying and selling costs a substantial percentage of the price in fees, taxes and agents’ commission, and those are paid whether or not the property gained a penny. Somewhere around five years is the commonly quoted break-even, longer where transaction taxes are high, and it moves with what prices and rents are doing locally. Below it, renting is usually the cheaper answer and frequently by a lot.
Renting also buys things that do not appear in the comparison. You can leave with a month’s notice when the job changes. Your monthly cost is a single known number with no roof in it. When the heating fails, it is somebody else’s afternoon and somebody else’s money. For anybody whose next three years are genuinely uncertain, that flexibility is worth more than the equity they would have built.
The last part is not financial and does not have to be. Wanting to paint a wall, to stay near a school, to stop a landlord deciding where you live next year — those are real reasons and they are allowed to win. The only mistake is believing you are making a financial decision when you have already made a personal one, because that is the version that ends with a house you cannot afford defended with arithmetic that was never the point.
How do I save for a house deposit?
Work out the whole cash figure you need including fees, divide it by the number of months you are giving yourself, and move that amount into a separate savings account on payday before anything else can reach it.
Start with the whole figure rather than the deposit, because the deposit is the part people plan for and the rest is the part that derails them. Add the closing costs, the cost of the move, whatever the place needs in its first month, and a buffer that is still intact once the keys are handed over. Buying a house is the most common way an emergency fund quietly gets spent, and the first year of ownership is a bad year to have none.
Then decide where it sits, and this one has a clear answer: money you intend to spend within a few years does not belong in the market. A fall of twenty per cent is an ordinary event that recovers over a decade, which is fine when the money is for retirement and catastrophic when it is for a completion date in eighteen months. A high-yield savings account is the boring, correct home for it.
The rate it grows at is the savings rate, and the reliable lever is timing rather than willpower: the transfer leaves on payday, before the month has had a chance to make a case for itself. Money that never sat in the current account is not money you decided against spending — it was simply never available, and that distinction is what makes the difference over two years.
Money that was never part of the monthly rhythm is the easiest to divert whole. A raise, a bonus, a tax refund, a side payment — none of them has an existing claim on it, so sending all of it to the deposit costs nothing you were already used to. And record it as saving rather than as spending: a fund that reads as an expense makes the month you were most disciplined look like the month you overspent.
What does owning a home cost that renting does not?
Property tax, buildings insurance, maintenance and the repairs that arrive without warning are all costs a renter never sees, and together they routinely add a third or more on top of the mortgage payment itself.
Property tax and insurance are the two that are certain, and in many places you will never pay them directly: the lender collects them monthly alongside the mortgage and pays them on your behalf out of an escrow account. That is convenient and it has one consequence worth knowing in advance — your monthly payment can rise without the interest rate moving at all, because a tax assessment or an insurance renewal went up. People treat that as an error the first time it happens. It is not.
Maintenance is the one that decides whether a household copes. A common planning figure is around 1% of the property’s value a year, and the trap is not the size of it but the shape: it is nothing, nothing, nothing, then a boiler; nothing, nothing, then a roof. Averaged over a decade the number is about right, and any single year will look nothing like it. This is exactly the job a sinking fund exists to do — a monthly amount set aside for a cost you cannot date but can absolutely predict.
Then the ones specific to the place: association or service charges, which can change by vote and which you have limited control over; ground rent or land charges where they exist; and utilities that are frequently higher than in a rented flat, because the house is bigger and its insulation is now your problem rather than a landlord’s.
None of this is an argument against buying. It is an argument for putting the whole number into the comparison, because the mortgage payment on its own is the figure that makes buying look cheaper than renting, and it is the one figure that is guaranteed to be incomplete.
What are closing costs, and how much should I expect to pay?
Closing costs are the fees that complete a purchase — lender charges, legal work, valuation, title, taxes and prepaid insurance — and they commonly come to somewhere between 2% and 5% of the price, due in cash on top of the deposit.
They surprise people for two structural reasons. They are not one fee but a list of a dozen or twenty small ones, so no single number ever gets quoted early; and they are due at the very end, at the exact moment the deposit has just left the account. A buyer who saved precisely the deposit discovers the gap with days to go, which is late enough that the only available fixes are bad ones.
They fall into four groups. Lender fees for arranging the loan, which are the ones most open to being questioned. Third-party fees for work actually done — the valuation, the title search, the survey, the legal work. Prepaid items and the escrow deposit, which are not really fees at all but tax and insurance paid in advance. And transfer taxes, which are set by a government and are the same wherever you shop.
Some of it is negotiable and some of it is not, and the difference is worth knowing before you spend energy in the wrong place. You can compare lenders on their own charges and you can sometimes choose your own provider for certain services; you cannot negotiate a transfer tax. In some markets a seller contributes towards the buyer’s costs, which is a term of the offer rather than a discount — worth asking about, and worth knowing it is a thing that exists.
Budget for them as their own line from the beginning, next to the deposit rather than inside it. A percentage of the purchase price, held separately, saved on the same schedule. The point is not precision this early — it is that the number exists in the plan at all.
