It is generally advised not to use all your savings to buy a house, as this can leave you financially vulnerable to emergencies, repairs, and closing costs. Experts recommend keeping at least 3–6 months of living expenses in an emergency fund after the down payment, which typically should be 5%–20% of the home's price.
If your mortgage rate is higher or similar to the savings rate you're looking at, overpaying your mortgage is likely to make greater financial sense. If the savings rate is higher than your mortgage rate, it might be better to prioritise saving for the future.
The "27.39 rule" (often rounded to $27.40) is a simple financial strategy to save $10,000 in one year by consistently setting aside $27.40 every single day, making it an achievable micro-saving habit to build wealth or an emergency fund. It turns the daunting goal of saving $10,000 into a manageable daily action, emphasizing consistency over large lump sums.
The "3-3-3 rule" in real estate isn't a single guideline but refers to different strategies: for buyers, it's about financial readiness (3 months savings, 3 months reserves, 3 property comparisons) or a financial affordability check (30% income, 30% down, 3x income); for agents, it's a marketing habit (call 3, note 3, share 3) or prospecting (talking to everyone within 3 feet). There's also a developer rule (1/3 land, 1/3 build, 1/3 profit), though it's considered outdated by some.
Red flags when buying a house include structural issues (foundation cracks, sloping floors), water problems (stains, musty smells, basement flooding signs, poor drainage), sloppy renovations (fresh paint covering damage, crooked finishes, DIY work), bad maintenance (old roof, deferred upkeep), and listing/market oddities (long time on market, multiple price drops, little info). Always get a professional inspection to uncover hidden issues with major systems like electrical, plumbing, HVAC, and roofing before buying.
You can typically afford an $800,000 mortgage with an annual income between $200,000 and $260,000. The amount you can borrow depends on more than just your salary, though. We'll cover those factors below. Luckily, you don't have to rely on guesswork to understand your potential monthly payments.
To afford a $700,000 house, you generally need an annual income between $180,000 to $235,000, depending on interest rates, down payment, and existing debts, with lenders often using the 28/36 rule (housing costs under 28% of gross income, total debt under 36%) to assess affordability. A 20% down payment ($140,000) is common, reducing your loan, but taxes, insurance, and other expenses add to the total monthly cost.
I tell young people all the time, by the time you hit 33 years old you should have at least $100,000 saved somewhere. Make that your goal. That's the age when it's really time to start getting FOCUSED on saving.
Not Saving Enough for a Down Payment
While some programs allow low or zero down payments, putting more money down can reduce your monthly payment and eliminate private mortgage insurance (PMI). Goal: Aim to make a down payment of at least 3%-5%, but if possible, 20% is ideal to avoid PMI.
However, most lenders still require your score to be at least 600 for an insured mortgage, even with a co-signer. How long does it take to raise my score enough to buy a home? Raising your credit score enough to buy a home (typically up to at least 600–680) can take anywhere from about 3 to 12 months.
It could wreck your credit
If your mortgage is too big, keeping up with those payments could mean falling behind on other bills. And if that happens, your credit score could take a serious beating. You'll generally see your score fall substantially with just a single late or missed bill payment.
Ways to pay off your home loan faster
You can't afford the house payment.
Don't buy a house if the monthly payment (including principal, interest, taxes, homeowners insurance and HOA fees) on a 15-year fixed-rate mortgage would be more than 25% of your take-home pay.
So, what do lenders look at when deciding to approve or deny an application? Lenders consider four criteria, also known as the 4 C's: Capacity, Capital, Credit, and Collateral.
