Automate Property Listings šŸš€

Turn Monday's 3 prompts into production-ready code

May 13, 2025
26 min read
šŸ  Real EstatešŸ Python + TypeScript⚔ 10 → 1000+ listings/day

The Problem

On Monday you tested the 3 prompts in ChatGPT. You saw how image analysis → feature extraction → description generation works. But here's the reality: you can't ask your agents to copy-paste 200 times per day. One agent spending 3 hours manually creating listings? That's $90/day in labor costs (at $30/hr). Across a busy brokerage handling 50 listings/day, you're looking at $135,000/year just on listing admin. Plus the inconsistencies that hurt SEO and the delayed time-to-market that costs you leads.

3+ hours
Per day creating listings manually
35% inconsistent
Descriptions missing key features
Can't scale
Beyond 10-15 properties/day

Watch the 3 prompts chain together automatically. This is what you'll build.

Real Estate Gotchas

Industry-specific challenges you'll hit in production. Here's how to handle them.

MLS Compliance & Data Standards

Build a normalization layer that maps your internal format to each MLS's requirements. Use RESO Data Dictionary as baseline.

Solution
# MLS normalization layer
class MLSAdapter:
    def __init__(self, mls_type: str):
        self.mls_type = mls_type
        self.field_mappings = self.load_field_mappings()
    
    def normalize_listing(self, internal_data: Dict) -> Dict:
        """Convert internal format to MLS-specific format"""

Image Processing & Storage

Compress images on upload, use CDN for delivery, cache AI analysis results. Don't re-analyze same image twice.

Solution
# Image processing pipeline
import hashlib
from PIL import Image
import io

class ImageProcessor:
    def __init__(self, cache_backend, cdn_url):
        self.cache = cache_backend

Duplicate Listing Detection

Use address + city + zip as primary key. Check for existing listings before creating new. Handle price changes as updates.

Solution
# Duplicate detection
import Levenshtein

class DuplicateDetector:
    def __init__(self, db_connection):
        self.db = db_connection
    
    async def find_duplicate(self, new_listing: Dict) -> Optional[str]:
Showing 8 of 53 lines

Market-Specific Terminology

Maintain region-specific terminology dictionaries. Include market context in prompts. Use local examples for few-shot learning.

Solution
# Region-specific terminology
class RegionalTerminology:
    TERMS = {
        'US': {
            'property_types': ['Single Family', 'Condo', 'Townhouse', 'Co-op'],
            'features': ['Hardwood floors', 'Central AC', 'Finished basement'],
            'rooms': ['Master bedroom', 'Family room', 'Mud room']
        },

Fair Housing Compliance

Post-process all descriptions through compliance filter. Flag and remove prohibited terms. Log all modifications for audit trail.

Solution
# Fair Housing compliance filter
import re
from typing import List, Tuple

class FairHousingFilter:
    # Prohibited terms under Fair Housing Act
    PROHIBITED_TERMS = [
        # Family status implications
