Why cleaning costs matter for your books

Cleaning costs are a legitimate expense in real estate investing, especially for flips where properties are often acquired in distressed conditions. Accurately tracking these costs ensures your profit calculations are correct. If you miss these, your actual profit will be lower than what your books show.

These expenses contribute to the overall cost basis of the property. A higher cost basis means a lower taxable gain when you sell. Proper bookkeeping allows you to fully account for all money spent to get the property ready for market.

It also provides a clear picture of your actual investment per property, which is vital for analyzing deal profitability and making future investment decisions. This is not tax advice.

Cleaning costs during acquisition vs. rehab phase

The timing of the cleaning dictates its accounting treatment. If you pay for initial cleaning, trash removal, or securing the property immediately upon acquisition, before any major rehab begins, these costs can be considered part of the acquisition expenses.

Once you start renovation, any subsequent cleaning, such as debris removal during demolition or a final deep clean before staging, falls under rehab expenses. The distinction is subtle but important for categorizing correctly in your accounting software.

Generally, costs incurred to make the property safe and accessible for contractors are acquisition-related, while costs incurred to enhance its marketability during or after construction are rehab-related. He or she should clearly categorize these.

Categorizing cleaning expenses in your software

In your bookkeeping software, create distinct categories for these types of expenses. For example, you might have 'Property Acquisition: Initial Clean-out' and 'Property Rehab: Cleaning & Waste Removal'. This level of detail helps with accurate reporting.

Attach receipts or invoices for all cleaning services directly to the expense entry. This provides a clear audit trail and justifies the cost. If you use a general ledger, ensure clear descriptions for each transaction.

Using specific categories also helps you analyze your spending patterns across different flips. You can see if certain types of properties consistently incur higher initial cleaning costs, influencing future offer amounts.

Tracking multiple cleaning service vendors

It is common to use different vendors for various cleaning tasks, such as a junk removal service for heavy debris and a professional cleaning crew for the final touch-up. Track each vendor separately in your books.

Assign a unique vendor profile to each company. This allows you to easily run reports on how much you are spending with each vendor over time. It also simplifies payment processing and year-end reporting for contractors.

Ensure that each vendor provides a detailed invoice that breaks down the services rendered. This helps you allocate the costs correctly between acquisition and rehab phases if a single vendor performs both types of work.

Impact on cost basis and profit calculations

Every dollar spent on cleaning, whether during acquisition or rehab, adds to the total cost basis of the property. This total cost basis is crucial for calculating your net profit when you sell. Higher costs mean a lower profit, but also potentially a lower taxable gain.

When you determine your ARV and calculate your maximum allowable offer, remember to include these cleaning costs in your projected expenses. Failing to do so will result in an inaccurate profit projection and potentially an overbid.

Regularly reconcile your cleaning expenses against your budget for each flip. This allows you to catch any overruns early and adjust your strategy if necessary. Knowing your true costs is key to smart investing.

Keeping clear records for potential audits

Maintain meticulous records of all cleaning expenses, just as you would for any other significant property cost. Keep all invoices, receipts, and proof of payment organized, either digitally or physically. This protects you in case of an audit.

Your records should clearly show the date of service, the vendor, the amount paid, and the specific property the service was for. Good record-keeping demonstrates that your expenses are legitimate business deductions.

Consider using cloud-based accounting software that allows you to upload and store documents electronically. This ensures your records are backed up and accessible whenever you need them, regardless of where you are.

Questions people ask

Are cleaning costs considered a repair or an improvement?

Generally, initial cleaning to make a property habitable or ready for rehab is typically seen as an expense that adds to the property's cost basis. It is usually not a 'repair' in the sense of fixing something broken, nor a 'capital improvement' like adding a new roof, but a necessary cost to prepare the asset.

What if the seller left a lot of junk?

Costs associated with removing large amounts of seller-left junk are explicitly part of your initial cleaning and acquisition expenses. These contribute to your total cost basis for the property.

Do I need separate accounts for each flip project?

While not strictly required, using separate bank accounts or at least robust tracking within your bookkeeping software for each project is highly recommended. It makes tracking expenses and profits per deal much clearer and simplifies financial analysis.
