Helping Self-Employed Business Owners Plan for Homeownership

By Doug Caldwell
Featuring special guest John Allis IV, Tax Advisor & Certified Public Accountant

Why We Wrote This Article

If you’ve read my recent article, Mortgage Money Myths: Should Self-Employed Borrowers Write Off Everything?, you know I believe one of the smartest things a business owner can do is involve both their mortgage lender and tax advisor before filing a tax return.

As I was writing that article, one thought kept coming back to me.

Readers shouldn’t only hear the mortgage perspective.
They deserve to hear directly from a tax professional as well.

So I reached out to my friend, John.

John has spent years helping individuals and business owners navigate tax planning, and I thought it would be valuable to sit down and have a conversation about one of the biggest misunderstandings in home financing.

This article isn’t about giving tax advice.

It isn’t about telling you how to prepare your tax return.

It’s about helping business owners understand how tax planning and mortgage planning often work best together.

I hope you enjoy our conversation.

Question 1

Why can’t self-employed borrowers qualify based on business income alone?

Doug:

One of the most common questions I hear from self-employed borrowers is:

“My business had a great year. Why can’t I qualify based on what I actually made?”

John:

Most business owners assume minimizing taxes always puts them in the best financial position, but minimizing taxes and qualifying for a mortgage don’t always move in the same direction.

Mortgage lenders generally qualify borrowers using documented taxable income, not simply the cash flowing through the business.

Many business owners have excellent cash flow while reporting relatively low taxable income after legitimate deductions.

Those deductions reduce taxes, but they may also reduce the income a lender can use when determining borrowing power.

Tax planning and financing goals should be coordinated rather than handled independently.

Professional Perspective

“Tax planning and financing goals should be coordinated rather than handled independently.”

Doug’s Perspective

This is probably the biggest surprise I see with self-employed borrowers.

No one is suggesting you should pay more taxes than necessary.

The goal is understanding how today’s tax decisions may affect tomorrow’s financing opportunities.

Planning creates options. Waiting limits them.

Question 2

When should someone planning to buy a home begin talking with their tax advisor?

Doug:

When should someone planning to buy a home begin talking with their tax advisor?

John:

As early as possible.

Ideally, twelve to twenty-four months before purchasing a home.

Early planning gives both your tax advisor and your mortgage professional time to build a strategy that supports your overall financial goals.

If you wait until you’re already shopping for homes, the tax returns that matter most have often already been filed.

Doug’s Perspective

I couldn’t agree more.

Some of my best client conversations happen long before anyone fills out a mortgage application.

Early planning often gives us more flexibility, more financing options, and fewer surprises.

Question 3

How do you balance minimizing taxes while preparing for future financing?

Doug:

How do you balance minimizing taxes while helping someone prepare for future financing?

John:

It starts with understanding the client’s goals.

If financing isn’t part of the conversation, we generally focus on minimizing taxes within the law.

If buying a home or refinancing is part of the client’s future, we have a different discussion.

Sometimes reporting a little more taxable income today may create greater borrowing power tomorrow.

It’s not about paying unnecessary taxes.

It’s about making informed financial decisions.

Doug’s Perspective

I love this answer because it illustrates something important.

Your tax advisor and your mortgage lender are not working against each other.

They’re solving different pieces of the same puzzle.

When those conversations happen together, clients usually benefit.

Question 4

Are there deductions business owners frequently misunderstand?

Doug:

Are there deductions business owners frequently misunderstand?

John:

Yes.

Depreciation, Section 179 elections, bonus depreciation, vehicle deductions, and significant one-time purchases often create questions.

Some items may be treated differently during mortgage underwriting depending on the loan program.

That’s why it’s valuable for your tax advisor and lender to communicate before major tax decisions are finalized.

Doug’s Perspective

One question I hear all the time is:

“I wrote off several thousand dollars in office supplies. Can’t you just add that back?”

Unfortunately, it isn’t that simple.

Recurring business expenses are generally viewed differently than documented one-time expenses.

Every loan program has different underwriting guidelines.

Every borrower has a different financial picture.

That’s why there isn’t a one-size-fits-all answer.

Question 5

What should someone do before filing taxes if they hope to purchase a home soon?

Doug:

What advice would you give someone before filing their tax return if they hope to purchase a home soon?

John:

Meet with both your tax advisor and your mortgage professional before filing.

Filing should be part of one coordinated financial plan, not two separate conversations.

One of the best statements John shared with me was:

“Filing is often treated as the finish line for taxes and the starting line for financing, when it should really be one coordinated decision.”

That perfectly captures why we wanted to write this article together.

Question 6

What is the difference between cash flow and taxable income?

Doug:

What is the difference between cash flow and taxable income?

John:

Cash flow is the money moving through your business.

Taxable income is what remains after tax rules and allowable deductions have been applied.

A business can generate excellent cash flow while reporting relatively low taxable income.

That’s why successful business owners are sometimes surprised by how mortgage underwriting evaluates their income.

Doug’s Perspective

I think this explanation helps connect the dots for many business owners.

Just because your business is healthy doesn’t necessarily mean your tax return tells the entire story.

Sometimes traditional financing works perfectly.

Other times, alternative documentation programs such as bank statement loans may be worth exploring.

Question 7

What’s one thing every self-employed borrower should know before applying for a mortgage?

Doug:

What’s one thing every self-employed borrower should know before applying for a mortgage?

John:

Involve your tax advisor and mortgage professional early.

Planning almost always creates more opportunities than reacting after your tax return has already been filed.

Doug’s Perspective

That has really become the theme of this conversation.

Planning beats guessing.

Final Thoughts

One thing became very clear while putting this article together.

Tax planning and mortgage planning are not competing strategies.

They’re complementary strategies.

The best financial decisions rarely happen in isolation.

Whether you’re planning to buy a home next year or five years from now, start the conversation early.

• Talk with your tax advisor.
• Talk with your mortgage professional.
• Build a plan together.

Buying a home isn’t simply about qualifying for a loan.

It’s about making smart financial decisions that support your long-term goals.

As I’ve said throughout The Smarter Mortgage Series:

My job isn’t to sell you the lowest interest rate.
My job is to help you make the best financial decision for your situation.
