Home Purchase Tax Deductions: What I Wish Someone Had Told Me Before Closing Day

Here’s a stat that blew my mind — the average American homeowner saves between $3,000 and $15,000 a year just from tax deductions related to their home. When I bought my first house back in 2016, I had absolutely no clue about any of this stuff. I left thousands of dollars on the table that first year, and honestly, it still stings a little!

Understanding home purchase tax deductions isn’t just some boring accounting exercise. It’s literally money back in your pocket, and who doesn’t want that?

Mortgage Interest Deduction: The Big One

Let’s start with the granddaddy of all homeowner tax breaks — the mortgage interest deduction. If you’ve got a mortgage on your primary residence, you can deduct the interest you pay on loans up to $750,000 (or $1 million if you bought before December 15, 2017). This was the first deduction I actually figured out on my own, and man, it made a difference.

My first year, I paid something like $12,000 in mortgage interest alone. Being able to deduct that from my taxable income felt like finding a $20 bill in an old jacket — except way, way better.

Property Tax Deductions

This one’s pretty straightforward but often gets overlooked. You can deduct state and local property taxes on your federal return, though the SALT deduction cap limits this to $10,000 total ($5,000 if married filing separately). That cap includes state income taxes too, so keep that in mind.

I remember being so frustrated when I realized the SALT cap ate into my deductions. My property taxes alone were close to $8,000, and once you add state income tax, I was already way past the limit. It is what it is, though.

Mortgage Points: The Deduction Nobody Talks About

Okay, this is the one that really got me. When you close on a house, you might pay discount points to lower your interest rate. Each point typically equals 1% of your loan amount. And guess what? Those points are generally tax deductible in the year you buy your home.

I paid two points on my mortgage — that was around $4,800. My accountant was the one who caught it because I totally forgot to mention it. So yeah, keep all your closing documents organized, people!

Don’t Forget About PMI

If you put less than 20% down on your home, you’re probably paying private mortgage insurance. The deductibility of PMI premiums has been a bit of a rollercoaster over the years — it keeps getting extended and then expiring. For recent tax years, it’s been available for qualifying homeowners, but you’ll want to check the current IRS guidelines because this one changes more often than my neighbor changes his lawn ornaments.

There are income limits on this deduction too. It starts phasing out once your adjusted gross income exceeds $100,000.

Home Office Deduction for the Self-Employed

Now here’s a little tangent — if you’re self-employed and work from home, there’s an additional deduction waiting for you. The home office deduction lets you write off a portion of your mortgage interest, property taxes, utilities, and even depreciation based on the square footage of your dedicated workspace.

I started freelancing on the side a few years ago, and this deduction was a game-changer. Just make sure the space is used exclusively for business — the IRS is pretty strict about that one.

Closing Costs That Qualify

Not all closing costs are deductible, but some definitely are. Here’s a quick rundown:

• Prepaid mortgage interest
• Property taxes paid at closing
• Loan origination fees (in some cases)

However, things like title insurance, appraisal fees, and home inspection costs are generally not deductible. I learned this the hard way when I tried to deduct basically everything on my closing statement. My tax preparer gave me a look I’ll never forget.

Your Wallet Will Thank You Later

Look, buying a home is one of the biggest financial decisions you’ll ever make. Taking advantage of every legitimate home purchase tax deduction available to you isn’t just smart — it’s essential. Everyone’s situation is a bit different, so definitely consult with a tax professional who knows your specific circumstances.
