How to Stack Lists in PropStream
By FlipProperties Editorial TeamPublished September 8, 2026Updated October 20, 2026PropStream figures checked October 2026
Filter stacking is a core PropStream skill — the difference between pulling a large unfiltered data dump and building a focused pipeline of likely sellers. Every filter removes owners who can't or won't sell. What remains is a shorter list of owners more likely to have a reason to sell.

The stacking principle
A raw lead-type pull is not a deal list — it's a starting point. Each lead list targets one situation: the owner is absent, or the property is in pre-foreclosure, or there's a tax lien. That single criterion is necessary but not sufficient. Most of those owners can't or won't sell.
Each filter you add asks a question: "Can this owner actually sell?" (equity filter — no equity means the bank won't release the lien). "Does this owner have a reason to sell?" (absentee filter — out-of-state means they can't manage the property). "Is this owner likely to respond?" (ownership-length filter — long-term owners are more reachable than recent flippers). A stacked list is the intersection of capacity, motivation, and reachability.
How stacking works in PropStream, and which thresholds to use
PropStream says one property can land on more than one lead list, such as a home with liens that's also in pre-foreclosure, and that stacking those lists "will identify high degrees of motivation and potential duplication." To see the overlap, open a marketing list and sort the marketing list column in descending order. Properties on more than one list move to the top.
| Filter or list | How PropStream defines it, or what you set | Common starting point |
|---|---|---|
| High Equity list | 50% or more equity, or $100,000 or more in equity | Use it as is for the deepest-equity leads |
| Equity (your own range) | You choose the percentage | 30%+ for a broader list; 50%+ to match the High Equity list |
| Ownership length | You choose the number of years | 2+ years to skip recent flips; 5+ years for longer-held homes |
| Vacant | Flagged as unoccupied by the USPS | Pair it with absentee and equity |
| Pre-foreclosure | The owner missed a mortgage payment and the lender filed a default notice | Filed within the last 90 days |
These starting points are choices, not rules. Tighten or loosen them based on how many leads your market returns. PropStream's Save Search keeps a stack's filters and can email you when new properties match.
Three worked examples
Absentee Owners
RESULT
Out-of-state absentee owners with equity and a long ownership history: a smaller list worth mailing first.
Pre-Foreclosure
RESULT
Active, equity-positive pre-foreclosures where the owner can still sell and has a reason to.
Vacant + High Equity
RESULT
A strong combined signal: empty, equity-rich, and the owner is somewhere else paying for nothing.
The universal filter hierarchy
These are the filters that matter across every category, in the order you should apply them:
Equity
Always first. No equity = no deal. Filter 30%+ for a broader list, or 50%+ to match PropStream's High Equity list. This is the capacity filter — without it, nothing else matters.
Occupancy / absentee
Is the owner living there? Second because it's a strong motivation proxy. Absentee + vacancy is a strong combination; owner-occupied requires a different conversation.
Ownership length
How long have they owned? 2+ years eliminates flips and traders. 10+ years means deep equity and likely mortgage-free. Long ownership correlates with motivation and deal flexibility.
Recency
How fresh is the signal? For distress categories (pre-foreclosure, bankruptcy, code violations), recency matters — contact while the filing is recent and the owner is still deciding what to do.
Common stacking mistakes
Stacking before pulling — select the lead type first, then filter. Filtering too early (before you know the pool size) over-narrows and you miss leads you didn't know existed.
Using all the filters — too many filters and you're hunting for unicorns. Leave enough list size for outreach to work.
Skipping equity because 'the motivation is strong enough' — a motivated seller with negative equity can't sell at your price no matter how badly they want to. Equity is non-negotiable.

Stacking means layering filters on top of each other so each one removes owners who can't or won't sell. Start with a lead type (for example, Absentee Owners — say 50,000 properties in your county, though your numbers will differ). Add filter 1 (out-of-state → fewer owners). Add filter 2 (equity 30%+) . Add filter 3 (owned 5+ years). Each filter narrows the list, and what remains is a short list of owners who have both the capacity (equity) and a reason (absentee, distress, life event) to sell — a hypothetical worked example, not a promise of results.
Absentee owners + out-of-state + equity 30%+ + owned 2+ years. This stack starts with the large absentee pool, narrows to the out-of-state subset, ensures deal room (equity), and eliminates flips and wholesales (ownership length). It's high-volume enough to produce leads every week, filtered enough to cut out most owners with no reason to sell, and the owners are reachable without the emotional complexity of distress categories.
Three filters is a good starting point. Two filters leaves the list too large for efficient outreach — you'll waste time and skip-trace money on low-probability contacts. Four or more filters can over-narrow and eliminate good leads — owners who might sell even if one filter doesn't perfectly match. Three filters is a reasonable balance: enough to isolate motivation, while still leaving a workable list you can actually call.
Yes. A property can meet several criteria at once, such as having liens and being in pre-foreclosure, so it shows up on more than one list. PropStream says those overlaps can point to higher motivation, and to duplicates you don't want to contact twice.
PropStream describes High Equity properties as having 50% or more equity, or $100,000 or more in equity. For a broader list, set your own equity range instead, such as 30% or more.
No. Stacking narrows a list to owners with more than one sign they might sell, which can make your marketing more focused. Results still depend on your market, your offer and your follow-up.
