Primary tax principle: Are flips inventory or investment?

The tax treatment of loan-related costs depends on how the IRS views the property. Two broad categories matter:

• Inventory (dealer) treatment: If you buy, renovate, and sell homes as part of a business (a “dealer” or a flipper), the property is usually treated as inventory. Costs tied to acquiring and improving the property are capitalized into inventory and become deductible as Cost of Goods Sold (COGS) when you sell the property. Income from the sale is ordinary business income, not capital gain.
• Investment (rental/long-term hold): If you buy a property to hold as rental or invest for appreciation, different rules apply—interest might be deductible on Schedule E, depreciation can be taken, and sales may generate capital gains.

Most short-term fix & flip projects fall into the inventory/dealer category. That classification largely determines how loan costs are treated.

How fix & flip loan interest is treated

Interest on a loan used for a fix & flip can generally reduce taxable profit, but how and when it reduces tax depends on your business classification and accounting method:

• Dealer/inventory sellers: Interest paid to acquire and renovate property is typically treated as a cost of doing business. Many taxpayers capitalize interest and other carrying costs into inventory and recover those costs through COGS when the property is sold. In practice, that means interest reduces your taxable profit at the time of sale (when inventory is sold).
• Cash-basis vs accrual-basis taxpayers: Cash-basis taxpayers generally deduct expenses (including interest) when paid. Accrual-basis taxpayers match expenses to the period when the associated income is recognized, which usually means capitalizing costs into inventory and deducting them upon sale.
• Short holding periods: Because most flips are short-term, capitalization then deduction at sale is common; however, if you can clearly separate financing interest from inventory production costs, you may deduct certain interest sooner. This is a technical area—work with your CPA.

Loan fees, points, and origination charges

Loan-related fees can be handled differently depending on their nature:

• Origination fees and points: If these costs are treated as interest or financing charges, they may be amortized over the life of the loan or capitalized into the cost of the property and then recovered through COGS when the property is sold.
• Broker fees and application fees: These are often deductible as business expenses or capitalized as part of the inventory cost; classification can depend on whether they relate to acquiring or improving inventory.
• Inspection, appraisal and closing costs: Closing costs that are acquisition-related are typically capitalized into inventory; routine transactional fees may be currently deductible if they are not acquisition or improvement costs.

Renovation and carrying costs

Direct renovation costs (materials, subcontractor labor, permits) are capitalized into the property’s cost basis and are recoverable through COGS when the property is sold. Other carrying costs such as property taxes, insurance, utilities, and HOA fees are usually ordinary business expenses and can be deducted in the period they are incurred—unless your accounting method requires capitalization into inventory.

Depreciation — usually not for flips

Depreciation applies to property used in a trade or business or held for production of income (for example, a rental). For a typical flip held only for resale, depreciation usually does not apply because the property is inventory, not a depreciable business asset. If you convert a flip property into a rental, depreciation rules will then apply from the conversion date forward.

Sales, profit reporting, and self-employment tax

When the property is treated as inventory, the gain from the sale is reported as ordinary business income. That income flows through your business tax return—Schedule C (sole proprietor), partnership return, or corporate return—depending on your entity. If you operate as a dealer in real estate, net profits can be subject to self-employment tax if your activities constitute a trade or business that generates self-employment earnings. This is an important distinction for tax planning and retirement contribution considerations.

Common accounting methods and the importance of consistency

Your accounting method (cash vs accrual) affects timing of deductions and income recognition. Many small flippers use cash accounting for simplicity, but accrual accounting is often required or preferred for inventory-heavy businesses. Once you adopt an accounting method, you must be consistent—or follow IRS procedures to change methods. A CPA can help determine the most advantageous and compliant method for your business.

Record-keeping checklist for fix & flip loans

Good records make tax time—and audits—much easier. Keep organized documentation for each project:

• Loan documents (promissory notes, closing statements, amortization schedule)
• Invoices and receipts for materials, labor, permits, and subcontractors
• Proof of payment (bank statements, canceled checks)
• Contractor agreements and change orders
• Sales contract, closing statement, and selling expenses (commissions, advertising)
• Detailed time log if you claim active participation or self-employment
• Entity formation and capitalization records if you use an LLC, S corp, or partnership

Entity choice matters—consult your CPA

Which entity you use—sole proprietorship, single-member LLC, multi-member LLC, S corporation, or C corporation—will affect how income, expenses, and self-employment tax are reported. For example:

• Single-member LLCs taxed as disregarded entities report activity on the owner’s Schedule C.
• Partnerships and multi-member LLCs report on Form 1065 and issue K-1s to owners.
• S corporations may offer payroll planning opportunities but add compliance complexity.

A CPA can model after-tax outcomes for each structure and recommend the best choice for liability protection and tax efficiency.

Typical fix & flip loan features and eligibility (what to expect)

While loan products vary across lenders, many fix & flip loans share common characteristics:

• Fast approval to close on time—many applicants get approvals within 7–10 business days.
• Loans structured to cover both purchase and renovation costs under one facility.
• Flexible short-term terms (often 6–18 months) designed for projects with quick turnarounds.
• Typical eligibility items include a minimum credit score (commonly around 620), non-owner-occupied properties, a renovation budget and timeline, proof of financial stability, and no recent bankruptcies (for example, within two years).
• Minimum loan amounts often start around $100,000 for many programs.

Practical tax planning tips from a CPA’s perspective

• Decide classification early: Work with your CPA before you buy the property to decide whether the activity will be treated as a trade or as an investment. That choice affects how you account for interest and renovation costs.
• Keep project-level accounting: Track each property as a separate job in your accounting software. This simplifies COGS calculations, profitability tracking, and tax reporting.
• Plan for taxes on sale: Remember taxes will be due when the flip closes. Set aside an estimated percentage for federal and state taxes so you aren’t caught short.
• Consider entity and payroll planning: If flipping is your primary business, evaluate payroll vs distributions, retirement plan options, and how to shelter income legally and efficiently.
• Document reasonable interest and fees: Keep loan amortization schedules and interest statements to back up deductions or capitalized interest in the event of audit.

Example: How a flip’s expenses flow to the tax return

Example (simplified): You buy a home for $150,000, spend $50,000 on renovations, pay $10,000 in interest and loan fees during the project, and sell for $240,000 with $10,000 selling costs (commissions and closing fees).

• Inventory basis = $150,000 (purchase) + $50,000 (renovation) + $10,000 (capitalized interest & loan fees, if applicable) = $210,000
• Net sales proceeds = $240,000 – $10,000 (selling costs) = $230,000
• Gross profit = $230,000 – $210,000 = $20,000 — reported as ordinary business income (subject to income tax and possibly self-employment tax, depending on entity and facts).

This example shows why capitalizing the right costs and tracking everything is essential—small mistakes change taxable profit materially.

When you might want to deduct rather than capitalize

Under certain narrow circumstances, some costs may be current deductions rather than capitalized. Examples include routine operating expenses not directly tied to production of inventory, or interest that cannot be allocated to a particular property. These are fact-specific determinations. Your CPA will evaluate the rules and your accounting method to decide which treatment is correct.

Audit risk and documentation

Flipping real estate often draws IRS attention because the line between investment and trade or business can change how income is taxed. Maintain meticulous documentation showing intent, timelines, budgets, and when you started active marketing and selling activities. Clear organization reduces audit risk and speeds up any required responses.

Bottom line

Fix and flip loans are a common and useful tool for short-term real estate projects. From a tax perspective, expect most renovation and acquisition costs to be capitalized into inventory and recognized as COGS when the property is sold. Interest and financing costs often reduce taxable profit either by current deduction or capitalization—how that works depends on whether you’re treated as a dealer, your accounting method, and the facts of the case. The rules are complex and fact-dependent, so get tailored advice from a CPA before and during your project.
