How to detect inconsistencies in lead source data

Detecting inconsistencies in lead source data is crucial for evaluating a provider's reliability and ensuring you are getting what you paid for. This involves cross-referencing information and looking for patterns that do not align with expectations.

Verify property address and owner details

The most basic check is to cross-reference the property address and owner's name with public records. Use your county's assessor's website or a property data tool to confirm the information. Look for misspellings, incorrect street numbers, or outdated owner names.

A significant discrepancy here can indicate poor data hygiene from the lead source. If the property address is wrong, your entire outreach effort will be wasted on the wrong homeowner.

Cross-reference motivation indicators

If your lead source provides motivation cues (e.g., 'pre-foreclosure,' 'tax delinquent'), verify these. A quick search of court records or tax records can confirm if the property truly aligns with the stated motivation.

Sometimes a lead might be labeled with a strong motivation, but a deeper dive into public records reveals the issue was resolved months ago. This is a crucial check for understanding the true urgency of the seller.

Check for duplicate entries or stale information

Maintain your own internal database of leads. Before uploading new leads, run a check for duplicates by property address or owner name. Receiving the same lead multiple times can inflate lead counts.

Also, pay attention to the age of the data. If you are consistently getting leads that are several months old with no updated information, their motivation may have changed or the property may have sold already.

Look for discrepancies in communication history

If the lead source claims to have text messaged homeowners, and Speed to Seller lists replies from those texts, compare the reported interaction with what you find when you call. Does the seller confirm the text message and the nature of his or her reply?

A seller who has no recollection of texting or whose replies seem to contradict the lead provider's description warrants further investigation. This helps ensure the lead's origin story matches his or her current state.

Track lead performance by source over time

Do not just look at individual leads; track the overall performance of each lead source in your CRM. Monitor metrics like contact rate, appointment set rate, and contract rate for each provider.

If one source consistently underperforms or has a higher rate of data discrepancies compared to others, it is a clear indicator of inconsistency. Over time, these patterns become evident and help you evaluate reliability.

Communicate findings clearly to the lead provider

When you find inconsistencies, document them thoroughly and communicate your findings to the lead provider. Provide specific examples and data points, not just general complaints.

A reputable provider like Speed to Seller should be open to feedback and willing to address issues with data quality. This communication is essential for holding them accountable and improving the quality of the leads you receive.

Questions people ask

What's the most common inconsistency I might see?

Often, it is outdated ownership information or a property address that does not exactly match public records. These small errors can waste a lot of your time and effort in outreach.

How quickly should I report an inconsistency to my provider?

As soon as you find it. Prompt reporting allows the provider to investigate and address the issue quickly. Waiting too long can make it harder to trace the source of the error.

If I find inconsistencies, does that mean the lead is bad?

Not always. A minor inconsistency might just be a data entry error. However, a pattern of significant or repeated discrepancies suggests a systemic issue with the lead source's data quality, which can impact the overall value of their leads.
