How to Stack Lists in PropStream

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 your actual deal flow.

The stacking principle
A raw lead-type pull is not a deal list — it's a starting point. Every PropStream lead type returns properties that match a single criterion: 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.
Three worked examples
Absentee Owners
RESULT
High-probability out-of-state absentee owners with equity and history — the ones who answer letters.
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 standard deals, 50%+ for maximum flexibility. 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.
Forgetting to save the stack — PropStream lets you save filter stacks as templates. Build each stack once, name it, and reuse it every week with fresh data.
Where to go next
Apply stacking to a specific category: How to Find Absentee Owners walks through the exact filter sequence for the highest-volume category. Or start with the five-step method to see how stacking fits into the full deal-sourcing workflow.

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 have real conversion potential, and the owners are reachable without the emotional complexity of distress categories.
Three filters is a good starting point. Two filters leaves the list 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.
