First, the one number that decides everything

Lenders don’t guess at what you can afford — they measure it. They look at how much of your monthly income already goes to debt, then see what’s left for a house payment. That ratio is called your debt-to-income, or DTI, and it’s the number that actually sets your ceiling. The calculator below works exactly the way a lender does — but it shows you two ceilings, not one: the maximum, and the comfortable number underneath it. The gap between them is where the rest of your life fits.

HOW MUCH CAN YOU AFFORD

Start with the payment
you believe in.

The bank will tell you your maximum. This shows you two numbers — the max, and the one that leaves you room to breathe. Buy at the ceiling you believe in, not the one your approval allows.

Colorado first-time buyer reviewing her home budget
Real Buyer, Real Numbers

She qualified for more than she bought — on purpose.

Jessica came in the way most first-time buyers do: wanting to know the biggest number the bank would approve. The approval came back higher than she expected. Most loan officers would have stopped there and pointed her at the top of it.

Instead, we asked a different question — not "what can you afford," but "what are you actually trying to build?" It turned out a house was one piece of it. She wanted her student loans and her car paid off inside five years, and maxing out a mortgage payment would have buried that goal.

So she bought below her ceiling. She put down less than she'd planned — keeping the rest of her savings liquid — and directed it at the debt instead. With excellent credit and a lower monthly payment on the house, she had real room in her budget to attack the loans, and walked out on track to be debt-free in five years and a homeowner.

That's the difference between someone who sells you a loan and someone who looks at the whole picture. The calculator above shows you your ceiling. The conversation is about whether you should buy there — or somewhere that leaves room for the rest of your life.

Understanding the Numbers

How the calculator figures your ceiling

01

Debt-to-Income (DTI)

DTI is the share of your gross monthly income that already goes to debt. Lenders cap it — most Qualified Mortgages draw the line where your total monthly debts, including the new mortgage, can’t cross a set percentage of your income. The calculator also shows a lower, comfortable target, because just because a lender will approve you at the max doesn’t mean you should live there. The comfortable number leaves room for savings, emergencies, and everything a house isn’t.

02

Down Payment & PMI

Your down payment sets your loan-to-value and whether you pay Private Mortgage Insurance. Put less than 20% down and PMI is required — it protects the lender, not you, and it’s a real monthly cost until it drops off at 20% equity. Colorado’s appreciation often gets buyers there faster than they expect. The calculator folds your PMI into the total automatically, so the number you see is the number you’d actually pay.

03

Total Monthly Payment

Your real monthly cost is far more than principal and interest. It includes property taxes, homeowners insurance, PMI if it applies, and any HOA or metro district fees. Buyers routinely underestimate the total — which is exactly why this calculator breaks out every component instead of hiding them.

Common Pitfalls

Affordability mistakes Colorado buyers make

01

Looking only at the purchase price

The sticker price is the starting point, not the cost. Taxes, insurance, PMI, and HOA or metro fees can push a lower-priced home’s monthly cost above a pricier one without them. The calculator above shows the all-in number — that’s the one that matters.

02

Ignoring metro district fees

Common in Castle Rock, Parker, Highlands Ranch, and newer developments across Colorado — metro district fees stack on top of HOA dues and fund the roads, water, and parks in newer communities. They’re not optional, and they can meaningfully change your monthly cost. Always ask about metro district taxes before you make an offer.

03

Maxing out at the top of your approval

A lender approving you at the maximum doesn’t mean you should spend there. At the ceiling, nearly half your income goes to debt — leaving little for savings, emergencies, or a life. Aim for the comfortable number instead. The calculator shows both for exactly this reason.

04

Underestimating PMI

With less than 20% down, PMI is a real monthly cost — money that protects the lender, not you — until you reach 20% equity. Colorado’s appreciation often shortens that runway, but plan for it as a cost until then, not an afterthought.

05

Taking the first insurance quote

Every lender requires active homeowners insurance before your loan can fund, and Colorado swings premiums hard — wildfire in the foothills, hail along the Front Range — so the same house can quote hundreds apart from one carrier to the next. That volatility is exactly why insurance is built into the practice: one call runs your property across 30+ carriers and places the right coverage at the right price, timed to fund your loan on schedule. You don’t chase quotes for weeks — the team that already compares every carrier does it for you.

06

Shopping for a house before you know your number

The most expensive mistake happens before you tour a single home: falling for a house first, then working out whether you can afford it. By then you’re emotionally committed, and the budget bends to the house instead of the house fitting the budget. Run your number first — the comfortable one, not just the max — and shop inside it. The right home inside your ceiling beats the wrong one that stretches it.

These numbers are a starting point, not a pre-approval. When you’re ready to turn them into a real plan, the next step is a conversation — where a loan program gets matched to your actual situation and goals. See our first-time home buyer guide, or explore FHA and VA loans in Colorado.

Common Questions

Home Affordability: Frequently Asked Questions

The calculator uses the standard debt-to-income (DTI) ratio that lenders apply when qualifying borrowers. It takes your gross monthly income, multiplies it by the maximum DTI ratio (43% for most loan programs), then subtracts your existing monthly debt payments. The remaining amount is your maximum allowable monthly housing payment. From there, it works backward — factoring in the interest rate, loan term, property taxes, insurance, PMI (if applicable), and HOA fees — to determine the highest purchase price that keeps your total housing cost within that limit.
DTI stands for debt-to-income ratio — the percentage of your gross monthly income that goes toward debt payments. Lenders use two DTI measurements: the front-end ratio (housing costs only, typically capped at 28–31%) and the back-end ratio (all debts including housing, capped at 43–50%). The 43% back-end limit is the threshold for Qualified Mortgages under federal rules. Some loan programs allow up to 50% with compensating factors like strong reserves or excellent credit. This calculator shows both a "comfortable" level at 36% and the maximum at 43% so you can see the range.
Private Mortgage Insurance (PMI) is required on conventional loans when your down payment is less than 20% of the purchase price. The exact amount depends on your loan size and credit; the calculator shows yours. The good news: PMI is not permanent. It automatically cancels when your loan balance reaches 78% of the original purchase price, and you can request removal at 80%. Colorado's strong home appreciation often accelerates the timeline to PMI removal.
Colorado has some of the lowest effective property tax rates in the nation — approximately 0.55% on average, compared to the national average of around 1.1%. This is largely due to the Gallagher Amendment (repealed in 2020 but with lasting effects) and the TABOR amendment, which limits how much property tax revenue can grow. For home buyers, this means property taxes add less to your monthly payment than in most other states.
Your down payment can come from savings, gift funds, the sale of a current home, or a HELOC on an existing property. Gift funds are accepted by FHA, VA, and conventional loans — FHA and VA allow 100% of the down payment to come from a gift. If you are using a HELOC on a current home, the new monthly payment on that HELOC counts toward your debt-to-income ratio. CO Home Equity helps you structure the optimal down payment strategy based on your specific financial situation.
The Third Leg

Insurance before closing, not after

Every lender requires active homeowners insurance before your loan can fund — and in Colorado, wildfire and hail risk swing premiums hard from one carrier to the next. Taking the first quote is how buyers overpay.
