Almost every buyer I work with starts with the same question. How much home can I afford? It's the right question to ask. But it has two different answers, and almost no one tells you that up front.
The first answer is the one your lender will give you. It's a math problem. They plug in your income, your debts, your credit, your down payment, and a few other inputs, and they hand you a number. That number is the maximum amount they're willing to lend you.
The second answer is the one you have to figure out yourself. It's the amount you'll actually be comfortable paying every month, for the next ten or fifteen or thirty years, while still living the life you want. That number is almost always lower than the first one and sometimes meaningfully lower.
The gap between those two numbers is where buyers get into trouble. It's where the phrase "house poor" comes from. And it's the most important thing I want every buyer I work with to understand before they fall in love with a listing. Here's how to think about both answers.
How Lenders Actually Calculate What You Qualify For
When you sit down with a lender for a preapproval, they're looking at a few specific things.
Gross income. Your income before taxes and deductions. Not what hits your bank account. Lenders work in pre-tax dollars, which is one of the first reasons their number can feel optimistic compared to your real budget.
Debt-to-income ratio (DTI). This is the big one. Lenders look at two versions. The "front-end" ratio is what percentage of your gross monthly income would go to your housing payment. Most lenders want this under 28-31%. The "back-end" ratio includes all your other monthly debt obligations (car loans, student loans, credit cards, child support) plus the housing payment. Most lenders want this under 43-45%, though some loan programs allow higher.
Credit score and credit history. Higher scores get you better interest rates. Lower scores get you higher rates or, in some cases, no loan at all. This is also where lenders look for red flags like recent collections, missed payments, or short credit history.
Down payment. How much cash you're bringing to the table. This affects not just how much you need to borrow, but also whether you'll need private mortgage insurance (PMI) and what interest rate you'll qualify for.
Employment stability. Lenders generally want to see two years of consistent employment, ideally in the same field. Self-employed buyers face additional documentation requirements.
From those inputs, the lender produces a maximum loan amount and a corresponding maximum purchase price, a.k.a. your preapproval number.
What the Lender's Number Actually Means
Here's the part that almost no one explains clearly. The lender's number is not a recommendation. It's a ceiling. It's the most they're willing to lend you while still being reasonably confident they'll get paid back.
The lender's incentive is to lend you as much as you can plausibly repay. That's not the same as lending you what you'll be comfortable repaying. Those are different goals.
A lender's preapproval also doesn't account for several real costs of homeownership that show up after closing. It calculates principal, interest, taxes, and insurance (the PITI payment). It does not calculate:
-
Routine maintenance and repairs
-
Utilities, which are often much higher in a home than in an apartment
-
Heating costs (a major factor in Vermont)
-
Property tax escalation over time
-
HOA or condo fees, in some cases
-
Furnishing the home
-
Lawn care, snow removal, and seasonal upkeep
-
The lifestyle costs you currently enjoy and want to keep enjoying
Most of these are not optional, especially the maintenance and heating costs. A reasonable rule of thumb is to budget 1-2% of your home's value per year for maintenance and repairs. On a $500,000 home, that's $5,000-$10,000 a year, or roughly $415-$835 per month set aside. Your lender does not include this in their calculation.
What's Different About Buying in Vermont
Vermont has some specific cost realities that out-of-state buyers and even some longtime Vermonters consistently underestimate.
Property taxes. Vermont property taxes are real. The effective rate varies significantly by town, but it's common to see annual property tax bills of $6,000-$12,000 or more on mid-range homes in Chittenden County. Your lender will include this in your monthly PITI calculation, but the figure they use is usually based on the current owner's tax bill, which may not reflect what your bill will look like after reassessment.
Heating costs. You probably know Vermont winters are long and can be fierce. Heating a 2,000 square foot home with oil, propane, or natural gas can run anywhere from $2,000 to $3,000+ per heating season depending on the home's age, insulation, and heating system. If you're moving from a smaller apartment or a warmer climate, this can be a significant adjustment.
Insurance. Homeowner's insurance in Vermont is generally reasonable, but if you're in a flood zone or buying an older home with knob-and-tube wiring or other quirks, premiums can climb quickly.
Older housing stock. Much of Vermont's housing inventory, especially in Burlington's Old North End, Winooski, and the older parts of Essex, is genuinely old. Old homes have character but they also have older roofs, older furnaces, older windows, and older everything else. Maintenance costs on a 100-year-old home can be a lot, and they tend to come in surprise lumps rather than predictable monthly amounts.
When I work with buyers moving to Vermont from other states, the property tax and heating cost realities are almost always the biggest surprises. Build them into your budget before you start touring homes, not after.
The Non-Negotiable Rule: Get the Actual Monthly Payment Before you Offer
This is the single most important thing I tell every buyer I work with. Before you submit an offer on any specific home, work with your lender to have them calculate the actual monthly payment for that specific property at the offer price you're considering. Not your preapproval number and not a rough estimate. The real number, with the real property taxes, the real insurance, and the real interest rate quote.
The reason is that the lender's preapproval is based on assumptions. The actual home you're offering on may have higher property taxes than the assumption built into your preapproval. Insurance might be higher for that property than the generic estimate. Rates may have moved. The HOA fee on a specific condo will change your math.
A great local lender will do this calculation in a few minutes, and they should be willing to do it as many times as you ask. If your lender is not willing or able to give you a real, property-specific monthly payment quickly, you have the wrong lender. This is not a luxury, it's the bare minimum.
I have this done for clients on every offer and counteroffer. Even if you've offered on three other homes this month. The numbers change with every property.
A Framework for Finding Your Own Comfortable Number
Here's the honest version of the affordability question. Take the lender's maximum, then ask yourself these questions:
-
If my income dropped by 20%, would I still feel okay about this payment? Job loss, reduced hours, and life changes happen. A payment that requires every dollar of your current income is a fragile payment.
-
Am I still able to save what I'm saving now? Retirement contributions, emergency fund, kids' college, vacations, future major purchases. If buying this home means stopping all other saving, you've stretched too far.
-
Can I absorb a $5,000 surprise without panic? Furnaces die. Roofs leak. Cars need transmissions. If your monthly housing payment leaves no margin for the unexpected, the unexpected will eventually wreck you.
-
Does this payment still leave room for the life I want? Travel, hobbies, dinners out, gifts, generosity. A home that costs you the rest of your life is not worth it.
If your answer to any of those is "no" at the lender's max, your honest number is lower than your qualified number. Don’t take it as a failure, rather take that as wisdom.
The Bottom Line
Buying a home should improve your life, not constrain it. The lender's number tells you what you can pay. Your honest number is what you should pay. Those numbers are rarely the same, and the gap between them is where house poor lives.
Work with a great local lender who will give you real, property-specific payment calculations on every offer you're considering. Build Vermont's real costs (taxes, heating, maintenance, older housing surprises) into your budget before you start touring. And give yourself permission to buy for less than your maximum. The buyers I see five years after closing who still feel good about their decision are almost always the ones who bought below their ceiling, not at it.
