Identifying the time sinks in report review

Break down the process of reviewing an inspection report into its individual components. This isn't just about reading the document. It includes reading the summary, meticulously cross-referencing findings with photographs, researching specific repair methods or material costs, getting quotes from contractors, and updating your initial repair estimates.

Each of these steps consumes your time. Some reports are straightforward, others are complex and require significant investigation. Be honest about how long each part takes you, as underestimating this will skew your overall cost analysis.

Assigning a hypothetical hourly rate to your time

To quantify your time, assign a hypothetical hourly rate to your work. This isn't necessarily your personal wage, but rather what your time is worth to your business in terms of potential revenue generation. For instance, suppose your time is hypothetically valued at £75 per hour when you are actively pursuing deals.

This figure helps put a tangible cost on every hour you spend on non-revenue-generating tasks, like report review. It highlights the opportunity cost of that time—what you could have been doing instead to move another deal forward. Please note: this is a hypothetical calculation for internal business analysis and not financial advice.

Tracking actual time spent on a few deals

For a realistic assessment, track your actual time spent reviewing inspection reports on your next few deals. Use a simple timer or a spreadsheet to log minutes for each phase: initial read, photo review, research, contractor calls, and estimate adjustments. Do this for a few deals to get a reliable average.

You'll likely find that what you initially thought took 30 minutes actually took an hour or more. This hands-on tracking provides the most accurate data for your specific process and the types of properties you typically encounter. Don't rely on guesswork.

Factoring in specialist consultations

Beyond your own time, include the time spent coordinating and communicating with specialists. If you need to call a plumber for a detailed quote on a specific issue or a structural engineer for an opinion, their time is a direct cost. Your time spent scheduling, explaining the issue, and reviewing their feedback is an indirect time cost.

These consultations are often necessary for accurate repair estimates, especially for complex issues. Ensure you account for both the direct fees paid to specialists and your own time investment in managing those interactions within your overall due diligence costs.

Incorporating time cost into your deal analysis

Once calculated, add this time cost to your other 'soft costs' for the deal, such as travel, administrative fees, or transactional funding interest. This provides a more comprehensive view of your total expenses. A hypothetical inspection report review might take three hours, costing your business a hypothetical £225.

Including this figure gives you a more accurate break-even point and a clearer picture of your actual profit margin on a deal. Neglecting time costs means you are underestimating your true expenses, which can lead to overpaying for properties or misjudging your actual returns. This is for internal business analysis and not financial advice.

Recognising diminishing returns

At some point, more time spent on an inspection report will not yield new, material information. Learn to recognise when you have enough data to make an informed decision. Over-analysing a report after you've identified the major issues and secured realistic repair quotes is unproductive.

Your goal is to mitigate risk and finalise your offer, not to become an expert on every possible minor defect. Focus on the big-ticket items that genuinely impact your after-repair value and your profit, then move forward with confidence.

Questions people ask

Why should I put a dollar value on my time?

Putting a hypothetical value on your time helps you understand the true cost of each deal, including indirect expenses. It makes you more aware of where your time is spent and encourages efficiency in your processes. Please note: this is for internal business analysis and not financial advice.

Is this only for complicated inspection reports?

No, it applies to all reports. While complex reports take longer, even straightforward ones consume valuable time. Tracking it consistently helps you build an average cost for this specific due diligence step across all your deals.

How does this affect my offer price?

By revealing more accurate total deal costs, including your time, it allows you to make more precise offers that protect your profit margins. If your time cost is higher than expected, your maximum offer price might need to adjust downwards.

What if I outsource report review?

If you outsource, the direct fee paid to the reviewer is a clear cost. However, you still need to factor in your own time spent finding, briefing, and managing that third party, as well as reviewing their summary or findings.
