A home affordability calculator income field looks simple, but one wrong input can move your price range by tens of thousands of dollars. This guide walks you through the inputs in order, so you finish with a realistic home price range built from your income, debts, and down payment. It uses the same debt-to-income logic Duane Buziak applies to Short Pump and Henrico County buyers. Before you start, have your last two pay stubs or tax returns, a list of monthly debts, and a rough savings figure.

Duane Buziak also flags where a NoTouch Credit Pull (a soft credit pull mortgage review) lets you check your numbers without a credit hit.
Step 1: Gather and Calculate Your Qualifying Monthly Income
Calculators expect gross monthly income, meaning pay before taxes and deductions. For a salaried buyer, divide the annual salary by 12. A $120,000 salary enters as $10,000, not the $7,400 or so that lands in your bank account.
Other pay types are averaged differently, and the exact method depends on the loan program and the underwriter. As a general pattern:
- Hourly: hourly rate times typical weekly hours times 52, divided by 12.
- Overtime, bonus, and commission: often averaged over two years, and usually counted only if the history is steady or rising.
- Self-employed and 1099: typically the average of net income after business deductions across two years of tax returns.
Treat these as starting points. Guidelines vary by program, so confirm how your specific pay will be counted before you rely on it.
Self-employed and 1099 buyers often find that tax-return income looks much lower than what the business actually earns. Duane Buziak can use bank statement loans or DSCR/Non-QM options for qualifying buyers, which look at deposits or property cash flow instead of the bottom line on a return.
Two mistakes distort this step more than any others:
- Entering net pay. This understates your budget and can make a home you could qualify for look out of reach.
- Counting income you cannot document. Cash side work or a raise you have not received yet will not be counted by underwriting, so a number built on it will not hold up.
Write down one final figure: your documented gross monthly income. Every later step builds on it.
Step 2: List Every Monthly Debt That Counts Toward Your DTI
Debt-to-income ratio (DTI) compares your monthly debt payments to your gross monthly income. Lenders look at two versions. Front-end DTI is your proposed housing payment divided by gross income. Back-end DTI adds all your other monthly debts to that housing payment before dividing. Back-end DTI usually drives the decision.
Debts that typically count:
- Auto loans and leases
- Student loans
- Minimum credit card payments (not the full balance)
- Personal loans
- Child support or alimony you are required to pay
Expenses that typically do not count: utilities, groceries, phone plans, streaming services, and insurance premiums outside the mortgage. They matter for your budget in Step 6, but they are not part of the DTI math.
Student loans deserve extra care. If your loans are deferred or on an income-driven plan, the payment shown on your statement may not be the one underwriting uses. Programs often substitute a formula, such as a percentage of the balance, so verify the current guideline for your specific program before you plug in a number.
To pull the figures, use the minimum payment on each recent statement and your credit report. A soft credit pull mortgage review can confirm balances and payments without a hard inquiry. Duane Buziak uses a NoTouch Credit Pull for this, which works as a no hard inquiry mortgage pre approval step, so checking your debts does not cost you points.
Add the list into one monthly total. You will use that total in Step 5.
Step 3: Set Your Down Payment and Cash-to-Close Number
Your down payment changes the loan amount, the mortgage insurance, and the payment. Minimums as of October 2026 vary by program:
- FHA: 3.5% down with eligible credit.
- Conventional: as low as 3% on eligible programs, with 5% to 20% more common.
- VA: zero down for eligible veterans and service members with entitlement.
- USDA: zero down, subject to income and property location eligibility.
Dynamo DPA and Turbo DPA can reduce the cash you need upfront. Availability, funding, and eligibility rules change, so confirm they are open and that you qualify before you build your plan around them.
Budget closing costs separately from the down payment. They commonly run a few percent of the purchase price, depending on the loan, the property, and the lender fees. Duane Buziak can structure no-out-of-pocket closing options in some situations, such as seller credits or lender credits, but those depend on the contract and the rate chosen, so treat them as something to confirm, not assume.
For a $480,000 home, 3.5% down is $16,800 and 5% down is $24,000. The closing costs come on top of that.
The most common mistake here is entering all your savings as the down payment. Keep reserves for the move, repairs, and the first months of ownership, because the first year of a house always has surprise bills. Decide on a down payment figure that leaves a cushion, and write it down alongside your estimated cash to close.
Step 4: Enter Realistic Rate, Taxes, Insurance, and Mortgage Insurance
The monthly payment lenders qualify you on is PITI: principal, interest, taxes, and insurance. Many calculators default to principal and interest only, which makes a home look cheaper than it is. Check that the PITI box is on, or add the extra items yourself.
Rate. Use a current market range, not the lowest teaser number in an ad. Rates move daily and depend on credit score, down payment, and loan type, so check a current quote as of October 2026 and run the calculator at the rate you were actually offered, plus a higher one (Step 6).
Property taxes. Henrico County sets its real estate rate per $100 of assessed value. In recent years the rate has been $0.87 per $100, but confirm the current figure on the Henrico County Department of Finance website. At $0.87, a $500,000 assessment means about $4,350 a year, or roughly $363 a month.
Homeowners insurance. Get a quote for your target home type, because premiums vary with age, roof, and coverage. Many buyers use a placeholder in the range of $100 to $200 a month until a real quote arrives.
Mortgage insurance. FHA loans carry MIP (mortgage insurance premium), which includes an upfront charge and an annual charge. Conventional loans with less than 20% down carry PMI (private mortgage insurance), priced by credit score and down payment. Include whichever applies.
HOA dues. Many Short Pump neighborhoods have monthly or annual association fees. Underwriting counts them, so add them.
Taxes and insurance are usually collected in an escrow account, meaning you pay one-twelfth each month with your mortgage payment and the servicer pays the bills when due. Calculators that leave these items out overstate how much house you can afford.
Step 5: Run the Numbers With a Worked Short Pump Example
This is an illustration, not a quote. Suppose a household earns $120,000 a year ($10,000 gross per month) and has $800 in monthly debts. At a 43% back-end DTI, total obligations cap near $4,300 ($10,000 x 0.43). Subtract the $800 in debts and about $3,500 is left for housing.
Assumptions: conventional loan, 5% down, 30-year term, an illustrative rate of 6.25% (not a current quote), Henrico taxes at $0.87 per $100, insurance at $150 a month, and PMI at an assumed 0.5% of the loan per year.
At a $480,000 price:
- Down payment: $24,000. Loan amount: $456,000.
- Principal and interest: about $2,808 a month.
- Property tax: $480,000 x 0.0087 / 12 = $348.
- Insurance: $150.
- PMI: $456,000 x 0.005 / 12 = $190.
- Total PITI: about $3,496. Add $800 in debts and total obligations are $4,296, or 43% of income.
Now compare that to the Short Pump median, which local market data places around $520,000 to $527,000. At $520,000 with the same assumptions, the loan is $494,000, principal and interest is about $3,042, tax is $377, insurance is $150, and PMI is about $206. That is $3,774 in PITI and a 45.7% DTI, roughly $275 a month over the cap. Closing that gap means a larger down payment, paying off debt (clearing $300 a month in payments adds roughly $43,000 of price room here), a lower rate, or a different program such as FHA or VA, or a DPA option if you qualify.
Programs differ on down payment, credit, and mortgage insurance, as shown below (as of October 2026; confirm current terms). The 2026 conforming limit for most of the country, including Henrico County, is $806,500 baseline, with a $1,249,125 high-cost ceiling, according to FHFA.
| Loan program | Minimum down payment | Typical credit minimum | Mortgage insurance | Loan limit | Soft pull availability |
|---|---|---|---|---|---|
| FHA | 3.5% | About 580 for 3.5% down; lower scores possible with more down | Upfront and annual MIP | Set by county; confirm for Henrico | NoTouch Credit Pull at pre-approval |
| VA | 0% with full entitlement | Duane Buziak works with VA down to 500 FICO | No monthly MI; VA funding fee may apply | No limit with full entitlement | NoTouch Credit Pull at pre-approval |
| USDA | 0% | Often around 640; varies | Upfront and annual guarantee fees | Income and property-area limits apply | NoTouch Credit Pull at pre-approval |
| Conventional | 3% to 5% minimum; 20% avoids PMI | Often 620 or higher | PMI under 20% down | $806,500 baseline; $1,249,125 high-cost ceiling (FHFA 2026) | NoTouch Credit Pull at pre-approval |
| Dynamo DPA / Turbo DPA | Pairs with an eligible loan to reduce cash needed | Follows the underlying loan | Follows the underlying loan | Follows the underlying loan | NoTouch Credit Pull at pre-approval |
Step 6: Stress-Test the Result Against Your Real Budget
The number from Step 5 is the most a program may allow. It is not necessarily a payment you can live with. Underwriting does not see your childcare bill, a daily commute to West Broad Village or Short Pump Town Center, or the retirement and savings goals you refuse to pause.
Rerun the calculator three ways, using the Step 5 inputs:
- 36% DTI: housing room of $2,800 after debts, or roughly a $380,000 home.
- 43% DTI: the Step 5 result, roughly $480,000.
- Program maximum (for example 50%, where a program and strong compensating factors allow it): roughly $581,000, but with very little room for anything else.
Then raise the rate by one full point. At 7.25% instead of 6.25%, the 43% scenario drops from about $480,000 to roughly $441,000, a difference of about $39,000. If your plan only works at the lowest rate, it is fragile.
Next, subtract your actual non-DTI costs from your take-home pay: childcare, fuel, utilities, groceries, and savings. Whatever remains is your true housing capacity.
The Consumer Financial Protection Bureau explains what a debt-to-income ratio is and why 43% became a common benchmark. Treat it as a reference point, not a target.
A pre-approval amount is a ceiling, not a recommendation. Pick the price where your monthly budget still works after the surprises.
Step 7: Confirm Your Number With a Soft-Pull Pre-Approval
A calculator estimates, but a pre-approval verifies. Duane Buziak runs a NoTouch Credit Pull so you get a mortgage pre approval without hard pull at the first stage. That is a no credit hit mortgage application step, so confirming your range does not lower your score.
The broker structure also matters for the price range itself. Duane Buziak shops 500+ wholesale lenders, while retail lenders offer one shelf of products. A different program, rate, or mortgage insurance structure can change the payment on the same loan amount, and so the price range that works for you. A mortgage pre approval without hard pull from a soft pull mortgage broker means you can compare options before committing to a single set of terms.
To get started, send:
- Your last two pay stubs
- W-2s or two years of tax returns (self-employed buyers may use bank statements instead)
- Recent bank statements
- A photo ID

Your Verified Range and When to Rerun It
Once pre-approval is complete, you will have a documented range, with the budget-tested figure from Step 6 sitting inside it. In the worked example, that meant a home near $480,000 on a $120,000 income, with $520,000 needing a bigger down payment, less debt, or a different program.
Rerun the calculator whenever something changes: a rate move, a new car payment, a raise, a student loan status change, or a different down payment source. A fresh soft pull keeps the numbers current without a hard inquiry.
