Generic searches waste time. Custom criteria laser-focused on your exact investment strategy deliver perfect matches automatically. Here's how to build search criteria that work as hard as you do.

Personalization = Precision

Generic search: "3 bed homes" = 10,000 results
Custom criteria: Your exact specifications = 15 perfect matches
Time saved analyzing bad deals: 99.85%

Build Custom Criteria

The Custom Criteria Builder Framework

5-Step Custom Criteria Process:

1

Define Your Strategy

What are you trying to accomplish? (flip, rent, BRRRR, etc.)

2

Set Financial Parameters

Price range, cash flow targets, profit minimums

3

Choose Property Characteristics

Type, size, condition, age that fits strategy

4

Target Geographic Areas

Specific neighborhoods/zips you want to invest in

5

Add Special Filters

Keywords, DOM ranges, motivated seller signals

Advanced Custom Criteria Techniques

Technique #1: Negative Criteria (Exclusions)

Specify what you DON'T want as much as what you do

Examples:

  • • Exclude: HOA fees over $200/month
  • • Exclude: Properties on busy streets
  • • Exclude: Condos (prefer full ownership)
  • • Exclude: Properties with pool (maintenance cost)

Technique #2: Ratio-Based Criteria

Set criteria based on ratios, not just absolute numbers

Smart Ratios:

  • • Rent-to-price: Minimum 1% (or 0.8% in hot markets)
  • • Price per sqft: Max 85% of neighborhood average
  • • Lot size to building: Minimum 3:1 ratio
  • • Days on market to price: Inverse relationship alert

Technique #3: Conditional Criteria

If/then logic for more intelligent filtering

Examples:

  • • IF price under $200K, THEN allow C neighborhoods
  • • IF 4+ beds, THEN accept up to $350K price
  • • IF DOM over 90, THEN lower price threshold to 60% ARV

Criteria Refinement Process

Monthly Criteria Review Checklist:

Check Results Quality

Are matches actually good deals? Or too many false positives?

Adjust for Market Changes

Update price ranges if market has shifted significantly

Add Learned Preferences

Discovered you hate 2-story homes? Add to exclusions

Test Variations

Create slight variations to see if you're missing opportunities

Common Criteria Mistakes

❌ Mistake #1: Copying Someone Else's Criteria

What works in their market/strategy won't work for yours.

Solution: Build criteria specific to YOUR goals and market

❌ Mistake #2: Set It and Forget It

Criteria from 2 years ago don't fit today's market conditions.

Solution: Monthly reviews and adjustments

❌ Mistake #3: Too Many "Must Haves"

15 absolute requirements = 0 properties will ever match.

Solution: 5-7 core criteria + nice-to-haves
