Hidden MLS Filters Most Investors Miss

1. Keyword Search in Listing Descriptions

Most MLS systems let you search listing text for specific phrases.

Power Words: "investor special," "cash only," "as-is," "estate sale," "relocating"

2. DOM (Days on Market) Ranges

Don't just search "over 60 days" - use specific ranges.

Sweet Spot: 45-90 days (motivated but not yet desperate/overpriced)

3. Price Per Square Foot Filters

Find underpriced properties by filtering below market $/sqft.

Strategy: Set max at 80% of neighborhood average price/sqft

4. Foreclosure/REO Status

Bank-owned properties often priced to sell quickly.

Filter: "REO," "Bank Owned," "Foreclosure" in property status

5. Lot Size for Future Development

Larger lots = potential to add ADU, subdivide, or expand.

Strategy: Filter for lots 50%+ larger than neighborhood average

Common Filtering Mistakes

❌ Mistake #1: Too Many Filters

15+ filters = 0 results. You've filtered out all properties.

Solution: Start with 5-7 core filters, expand if needed

❌ Mistake #2: Ignoring Price Per Square Foot

Listing at $200K seems cheap until you see it's $300/sqft.

Solution: Always include $/sqft filter below market average

❌ Mistake #3: Not Using Keyword Searches

Missing motivated sellers who signal intent in listing descriptions.

Solution: Add keyword filters for investor-friendly terms
