How Speed to Seller identifies duplicate seller replies

We implement specific systems to identify and filter out duplicate seller replies before they reach our marketplace. This ensures you are always getting a fresh, unique lead ready for your outreach.

What counts as a duplicate reply?

A duplicate reply, for our purposes, is when the same homeowner, at the same property address, responds to our outreach within a specific time frame. This prevents investors from buying what they perceive as the same lead multiple times. Our system focuses on providing distinct opportunities.

It is important to differentiate between a duplicate reply and a re-engagement from a seller after a long period. We recognize that seller situations change, so our definition of a duplicate has a time component.

Our initial filter: matching phone numbers

The first layer of our duplicate detection system relies on the primary phone number used by the homeowner to reply. When a text reply comes in, our system cross-references that phone number against recently received replies from other homeowners. This is a quick and effective way to catch immediate duplicates.

If a reply comes from a number already associated with an active lead in our system, it is flagged for further review. This helps ensure that the same person is not being presented as a new lead if they happen to reply from the same number again shortly after an initial response.

Beyond phone numbers: address and name cross-referencing

While phone numbers are a strong indicator, we also cross-reference replies using property addresses and owner names. Sometimes a homeowner might reply from a different phone number, or perhaps a spouse or other household member replies for the same property. We look at the property address as the core identifier.

Our system checks if a reply's associated property address or owner name matches a recently listed lead. This multi-layered approach helps us catch duplicates that a single data point might miss, ensuring a higher quality of unique leads for our investors.

Timing out replies: when a "duplicate" becomes a new lead

Motivation levels and life circumstances change over time. A seller who replied six months ago and did not move forward might be in a different position today. Our system recognizes this by 'timing out' replies after a certain period.

If a homeowner replies again after this set timeframe, even if he or she previously replied for the same property, we consider it a fresh lead. This reflects a renewed or changed motivation and provides a new opportunity for investors to engage.

Seller intentions: why some replies look similar

Occasionally, you might encounter leads that feel similar even if they are not exact duplicates by our system's definition. This can happen if, for example, two different heirs for an inherited property reply separately from their own numbers, or if a homeowner replies to multiple outreach campaigns over a long period from different numbers.

Our system aims to filter out direct duplicates from our own campaigns. We prioritize the homeowner's explicit reply and the uniqueness of that specific response for listing on the marketplace.

Maintaining lead integrity: what this means for you

Our meticulous process for identifying and filtering duplicates means you can trust the freshness of the leads you buy on Speed to Seller. You are getting replies from homeowners who have not been presented to investors on our platform in a recent, active timeframe. This saves you time and resources.

We are committed to providing unique, high-intent leads. Our methodology is built to minimize wasted effort on your part by ensuring each lead represents a genuine new opportunity for you to connect with a motivated seller.

Questions people ask

What if a seller texts back months later? Is that a duplicate?

No, if a seller texts back after our defined 'timeout' period, we consider it a new, fresh lead. We recognize that a seller's situation and motivation can change significantly over several months, warranting a new opportunity.

How do you handle multiple numbers for the same property?

Our system cross-references not only phone numbers but also property addresses and owner names. If different individuals associated with the same property reply, we evaluate the uniqueness of the reply and the overall context before listing.

Do you ever re-list replies?

Yes, if a homeowner replies again after our 'timeout' period, he or she is considered a new lead and can be re-listed. This is because the lapse in time indicates a potential change in his or her selling situation or motivation.
