Pre-foreclosure is the lead source every wholesaler learns first. It makes sense: someone behind on their mortgage is, almost by definition, a motivated seller. So the question I hear is whether code violations are even worth bothering with when pre-foreclosure exists.
Having worked both in Seattle, here's my honest take. They're not competitors. They're two different distress signals, and the second one is far less crowded.
What pre-foreclosure leads are
Pre-foreclosure leads are properties where the owner has fallen behind on the mortgage and the lender has started the foreclosure process, but the home hasn't been sold at auction yet. The trigger is a public filing, a Notice of Default or a lis pendens, recorded with the county. That filing is what list vendors scrape and sell.
So pre-foreclosure, like code violations, is a public record. Neither one is secret data. The difference is who else is looking at it, and what the signal actually tells you.
The honest comparison
| Pre-foreclosure leads | Code violations | |
|---|---|---|
| Signal | Financial distress (missed payments) | Property distress (neglect, vacancy, unsafe conditions) |
| Source | County NOD / lis pendens filings | City code-enforcement records |
| Cost | Often paywalled (RealtyTrac, ForeclosuresDaily) | Often free open data |
| Competition | Very high, everyone buys these | Low, the data is fragmented |
| Timing | Late, the clock is already running | Earlier, before it escalates |
| Owner state | Defensive, over-contacted | Usually not yet besieged |
Pre-foreclosure is a strong signal that's badly saturated. The list is sold to every wholesaler, agent, and "we buy houses" operator in the market. By the time you reach the owner, they've had a dozen letters and three voicemails this week. The intent is high, but so is the noise, and in several states there are rules restricting how and when you can solicit someone in active foreclosure. Worth knowing before you mail.
Code violations are a quieter, earlier signal. A vacant-building flag or an emergency order shows an owner who has checked out or can't keep up, often months before any financial filing hits the county. Fewer investors mine it because the data is scattered across city portals in different formats. That friction is exactly why the leads aren't picked over. Since the records are public, the only barrier is the work of assembling them. (More on that in are code violations public record?.)
So which one wins?
Wrong question. The best lead isn't one or the other, it's the overlap.
A property with an open code violation and a recent pre-foreclosure filing is about as motivated as a seller gets: the house is falling apart and the money has run out. Those are the names I move to the top of the stack. Code violations get me in early and away from the crowd; pre-foreclosure confirms the financial pressure. Stacked signals beat any single list, which is the whole idea behind how to find distressed properties.
If I had to start with one on a budget, I'd start with code violations, because they're usually free, less competitive, and they surface owners before the pre-foreclosure crowd shows up. Then layer pre-foreclosure on top as a confirmation signal, not your only list.
How to actually work it
The mechanics are the same for both: pull the records, rank by how serious and how recent the distress is, cross-reference with owner data (absentee owners convert best), skip trace, and reach out before the property lists. For the violation side, which case types matter most is broken down in the investor's guide to code violations.
That stacking is what I built FlaggedLeads to do for Seattle: it scores every property by distress signal and surfaces the ones worth contacting. The free Seattle map shows where the violations are, so you can see the quieter list for yourself.
Frequently Asked Questions
Are pre-foreclosure leads worth it?
Yes, but with eyes open. The intent is high because the owner is under real financial pressure. The catch is saturation: these lists are sold widely, so you're competing with a crowd, and some states restrict foreclosure solicitation. Use them, but don't rely on them as your only source.
Where do pre-foreclosure leads come from?
A public county filing, a Notice of Default or lis pendens, that the lender records when an owner falls behind. List vendors scrape those filings and resell them, but you can also pull them directly from the county recorder.
Are pre-foreclosure lists free?
The underlying filings are public, so you can assemble a list yourself from county records for free. The convenient, pre-packaged lists from services like RealtyTrac or ForeclosuresDaily are paid, often $50 to $500 a month.
Code violations or pre-foreclosure, which is better for wholesaling?
Code violations are earlier and far less competitive; pre-foreclosure is a stronger financial signal but heavily worked. For most wholesalers, code violations are the better starting point, with pre-foreclosure layered on as confirmation.
Can you combine code violations and pre-foreclosure leads?
That's the highest-value move. A property with both an open violation and a pre-foreclosure filing is a top-tier motivated seller. Stacking distress signals beats working any single list.
