Mortgage interest is deductible only on the first $750,000 of home acquisition debt, and only if your itemized deductions beat the standard deduction. That second test is where most Shenandoah Valley buyers stop benefiting, because loans at Valley price points are small enough that the standard deduction usually wins. Understanding the mortgage interest deduction limits for 2026 helps you size a payment you can carry without counting on a refund. Duane Buziak, NMLS #1110647, of Blue Mountain Mortgages by Duane Buziak, walks through the debt cap, the itemizing test, how USDA, VA, FHA, and conventional loans differ, and a worked Augusta County example. This is general information, not tax advice, and a CPA makes the filing call.
The $750,000 Debt Cap and the Rules Around It
Federal law lets you deduct interest on up to $750,000 of “acquisition debt,” the combined loans used to buy, build, or substantially improve your main home and one second home. Loans taken out on or before December 16, 2017 keep the older $1,000,000 limit. As of 2026, the 2025 federal tax law made the $750,000 cap permanent instead of letting it expire, but confirm current status with your tax professional before filing.
The cap applies to the loan balance, not the purchase price. If your balance is $1,000,000, only $750,000 of it qualifies, so roughly 75% of your interest is deductible. The actual calculation uses average balances during the year, so your CPA’s figure may differ slightly.
Purpose matters as much as size. Interest counts only when the borrowed money went into the home. A home equity loan used to pay off cards or buy a truck does not qualify, even though the house secures it. In a cash-out refinance, the proceeds are split by use: the part that replaces your old acquisition debt or pays for improvements is deductible, and the part spent elsewhere is not.
Two limits get confused constantly:
- The tax cap: $750,000 of acquisition debt, an IRS rule about deductibility.
- The conforming loan limit: $806,500 in 2026 ($1,249,125 in high-cost areas), a loan-sizing rule that decides whether a mortgage is conforming or jumbo.
They are different numbers for different purposes. A loan of $790,000 is conforming but still subject to the $750,000 tax cap, so a small slice of its interest is not deductible.
The authority on all of this is IRS Publication 936, the Home Mortgage Interest Deduction guide. Read it or hand it to your CPA before you make any assumptions about your return.
Why Many Valley Homeowners Never Use the Deduction
Mortgage interest only reduces your taxes if your total itemized deductions exceed the standard deduction. For 2026, the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly, per the IRS (Tax Topic 551). Your itemized total is mortgage interest plus state and local taxes (subject to the SALT cap, which the 2025 law raised to roughly $40,000 for 2026 with phase-downs at high incomes), charitable gifts, and a few other items.
Valley price points work against that math. The Census QuickFacts page for Augusta County and the page for Rockingham County show median owner-occupied home values well below what buyers pay in Northern Virginia. Check the current figure and data year on those pages. Smaller loans mean smaller interest, and county property tax bills rarely add enough to close the gap. A married couple needs more than $32,000 in itemized items before the first dollar of mortgage interest saves them anything.
The most common mistake is assuming “I have a mortgage, so I get a tax break.” What you actually deduct is the amount by which your itemized total exceeds the standard deduction, taxed at your bracket. If itemizing beats the standard deduction by $3,000 and you are in the 12% bracket, the deduction is worth about $360.
Timing matters too. Early payments on a 30-year loan are mostly interest, so the deduction is largest in year one and shrinks every year as principal grows. A buyer who barely clears the standard deduction in year one will likely fall below it by year five or six.
Duane Buziak shows buyers the after-tax picture up front, so the payment you qualify for never depends on a deduction you may not receive. Whether to itemize on your actual return is a decision for a CPA.
How Loan Type Changes What You Can Deduct
USDA and VA
USDA loans in eligible Valley areas, such as much of Page, Shenandoah, Rockingham, and Augusta counties, allow zero down. That means a larger loan and more interest than a down-payment loan on the same house. The upfront guarantee fee is 1% and the annual fee is 0.35% as of 2026 (see USDA Rural Development). How those fees are treated for tax is an open question worth putting to your CPA, since they resemble mortgage insurance under the restored rules discussed below.
Eligibility depends on the property address and on household income against that county’s limit for your household size. Check the address on the USDA eligibility map, and ask Duane Buziak to pull the current county income limit before you shop.
VA loans carry a funding fee, which is waived for veterans with service-connected disability ratings (see VA.gov). Whether and how the fee is deductible is a question for your CPA against current IRS guidance.
FHA and Conventional
Mortgage insurance premiums became deductible again beginning with tax year 2026 under the 2025 tax law, treated as qualified residence interest. As of 2026, details such as income phase-outs and which premiums qualify should be confirmed in current IRS guidance, because they determine whether the FHA annual premium or conventional private mortgage insurance helps you at all.
Points and Jumbo Loans
Discount points paid at closing may be deductible in the year paid when you meet the conditions in Publication 936, including that they are paid on a loan for your main home and are a normal charge in your area. Otherwise they are spread over the life of the loan. Jumbo loans over $750,000 are where the cap actually bites, since interest on the balance above that line is not deductible.
Worked Example: A $275,000 Home in Augusta County
Suppose a buyer purchases a $275,000 home in Augusta County near Staunton. All figures below are illustrations at an assumed 6.5% rate on a 30-year fixed loan, not a rate quote.
Scenario A, USDA at 0% down. The base loan is $275,000. Financing the 1% guarantee fee ($2,750) makes the loan $277,750, with $0 out of pocket for the down payment and no-out-of-pocket closing options possible depending on the deal. Principal and interest is about $1,756 a month. The 0.35% annual fee adds roughly $81, for about $1,837 before taxes and insurance.
Scenario B, FHA at 3.5% down. The down payment is $9,625, leaving a base loan of $265,375. Financing the 1.75% upfront premium ($4,644) makes the loan $270,019. Principal and interest is about $1,707. An annual premium of roughly 0.55% adds about $124, for about $1,830. The monthly payments land within a few dollars, but Scenario B needs $9,625 in cash first.
Year-one interest. Scenario A pays about $17,960 in interest in year one, and Scenario B about $17,460. Assume $2,000 a year in property tax (an illustrative figure). That puts itemized housing costs near $19,960 and $19,460. A married couple filing jointly needs $32,200 to beat the standard deduction, so the deduction is worth $0 unless they have $12,000 or more in other itemized items. A single filer, with a $16,100 standard deduction, clears it by about $3,000 to $3,900 once state income tax and charitable gifts are counted, which is worth a few hundred dollars at the 12% bracket.
Contrast case. Now take a $1,000,000 loan on a home near Winchester in Frederick County. Year-one interest at 6.5% is about $64,700. Only 75% is deductible under the cap, or roughly $48,500. About $16,200 of interest earns no deduction at all.
What matters in both cases is cash to close and the monthly payment. Duane Buziak uses the NoTouch Credit Pull to pre-qualify buyers without a hard inquiry, so this comparison can be run before any credit impact.
Broker or Lender: Who Helps You Plan Around These Limits?
Every option below can produce a Loan Estimate. What differs is how many programs sit behind the quote and whether you take a credit hit to see it. Competitor cells contain only what applies to any single-company provider; ask each for its current credit-pull policy in writing.
| Option | Loan shelf | How pricing is shown | Pre-approval credit pull |
|---|---|---|---|
| Duane Buziak (independent broker) | Wide wholesale lender shelf, so USDA, VA, FHA, conventional, and jumbo are compared side by side | Multiple lender quotes compared on one Loan Estimate basis | NoTouch Credit Pull, no hard inquiry to pre-qualify |
| Rocket | Its own product lineup | One company’s rate sheet | Confirm policy with Rocket |
| Movement | Its own product lineup | One company’s rate sheet | Confirm policy with Movement |
| Alcova | Its own product lineup | One company’s rate sheet | Confirm policy with Alcova |
| Single-bank local lender | That bank’s programs only | One institution’s rate sheet | Ask before applying |
Duane Buziak brings $95.6M in production, 1,400+ five-star reviews, Top 1% Nationwide standing, and Scotsman Guide Top Originator recognition in 2025 and 2026. As an independent broker, he shops a wide wholesale lender shelf instead of one rate sheet, which matters when USDA, FHA, and conventional pricing differ by the same few dollars a month as in the example above.
No mortgage broker gives tax advice, and Duane Buziak does not. A good one runs the payment and after-tax scenarios, then refers you to a CPA.
Mortgage Interest Deduction FAQs for Valley Homebuyers
Is there a mortgage interest deduction limit in Virginia in 2026?
Yes. As of 2026, the federal limit is interest on $750,000 of acquisition debt, or $1,000,000 for loans taken out on or before December 16, 2017. Virginia follows its own rules for state returns, so ask a CPA about the state side.
Does a Rockingham County homeowner benefit from itemizing?
Usually only if total itemized deductions exceed the 2026 standard deduction of $16,100 single or $32,200 joint. At Harrisonburg-area loan sizes, many owners fall short. A CPA can run your actual figures.
Can Augusta County USDA borrowers deduct interest?
Yes, USDA loan interest qualifies like other acquisition debt, if you itemize. The treatment of the USDA guarantee and annual fees should be confirmed with a CPA and IRS Publication 936.
Are FHA mortgage insurance premiums deductible in 2026?
As of 2026, the 2025 tax law made mortgage insurance premiums deductible again, beginning with tax year 2026. Confirm current income limits and qualifying premiums with the IRS or your CPA before counting on it.
How is interest deducted on a Frederick County jumbo loan?
Only interest on the first $750,000 of balance is deductible. On a $1,000,000 loan, roughly 75% of interest qualifies, with exact figures based on average balances.
Is the interest on a Warren County second home deductible?
Often yes, if it qualifies as your second home and the combined debt on both homes stays within the $750,000 cap. Rental use of the property changes the rules, so check Publication 936 or ask a CPA.
Does refinancing in Shenandoah County change the deductible amount?
It can. Refinanced debt stays deductible up to the old acquisition balance, and cash taken out is deductible only to the extent it funds the home. A conventional cash-out refinance is capped at 90% loan-to-value, and a VA cash-out can reach 100%.
Are points on a Page County purchase deductible?
Often, when paid on a main-home purchase and the conditions in Publication 936 are met, you can deduct them in the year paid. Otherwise they are spread over the loan’s life. Confirm with a CPA.
The Limit That Matters, and the Next Step
For most Valley buyers, the deduction depends on loan size and on whether itemizing beats the standard deduction, not on the $750,000 cap. Plan your payment around what you can comfortably afford, not a refund you may never see.
