Automate Investment Analysis 🚀

Turn Monday's 3 prompts into production-ready code

September 2, 2025
18 min read
🏢 Real Estate Tech🐍 Python + TypeScript⚡ 0 → 5000 deals/day

The Problem

On Monday you tested the 3 prompts in ChatGPT. Cool! You saw how extraction → validation → questions works for investment analysis. But here's the thing: you can't ask your analysts to copy-paste 200 times per day. One analyst spending 3 hours running prompts manually? That's $90/day in labor costs. Multiply that across a busy investment firm and you're looking at $27,000/year just on deal screening. Plus the copy-paste errors that lead to missed opportunities or bad investments.

3+ hours
Per day running prompts manually
35% error
From copy-paste mistakes
Can't scale
Beyond 10-20 deals/day

The Code

Three levels: start simple, add reliability, then scale to production. Pick where you are.

Basic = Quick startProduction = Full featuresAdvanced = Custom + Scale

When to Level Up

1

Simple API Calls

  • Sequential processing
  • Basic error handling
  • Manual review of all results
  • Local logging
  • Cost: ~$50-100/month in API calls
Level Up
2

Add Reliability Layer

  • Retry logic with exponential backoff
  • Queue system (Redis/RabbitMQ)
  • Automated confidence scoring
  • Structured logging (Winston/ELK)
  • Database for results tracking
  • Cost: ~$300-500/month (API + infrastructure)
Level Up
3

Framework Orchestration

  • Multi-step workflow orchestration
  • Parallel processing where possible
  • Smart caching of common queries
  • Real-time monitoring dashboard
  • A/B testing of prompts
  • Integration with deal management systems
  • Cost: ~$800-1,500/month
Level Up
4

Multi-Agent System

  • Dedicated agents per task type
  • Load balancing across API providers
  • Advanced caching and rate limiting
  • Custom model fine-tuning
  • Real-time market data integration
  • Automated deal scoring and ranking
  • Multi-region deployment
  • Cost: Custom pricing, typically $2,000-5,000/month

Real Estate Tech Gotchas

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

Market Data Staleness

Implement time-based cache invalidation + real-time API checks for high-value deals.

Solution
# Cache with TTL
import redis
import json
from datetime import timedelta

redis_client = redis.Redis(host='localhost', port=6379, decode_responses=True)

def get_market_data(address: str, max_age_hours: int = 24):
Showing 8 of 27 lines

Multi-Currency Handling

Detect currency from address, convert to USD for comparison, store both values.

Solution
# Currency handling
import requests
from typing import Dict

def normalize_price(price: float, currency: str, address: str) -> Dict:
    # Detect currency if not provided
    if not currency:
        currency = detect_currency_from_address(address)
Showing 8 of 24 lines

Incomplete Listing Data

Use ML to estimate missing values based on similar properties + neighborhood averages.

Solution
# Estimate missing values
def estimate_missing_data(deal: Dict, comps: List[Dict]) -> Dict:
    # Calculate neighborhood averages
    avg_hoa = sum(c.get('hoa', 0) for c in comps) / len(comps)
    avg_tax_rate = sum(c.get('tax_rate', 0) for c in comps) / len(comps)
    
    # Estimate rent using price-to-rent ratio
    avg_ptr = 0.008  # typical 0.8% monthly rent
Showing 8 of 17 lines

Regulatory Variations

Maintain jurisdiction database + flag deals requiring manual legal review.

Solution
# Jurisdiction rules
JURISDICTION_RULES = {
    'CA': {
        'rent_control': True,
        'max_annual_increase': 0.05,
        'requires_legal_review': True
    },
    'TX': {

Deal Volume Spikes

Auto-scaling queue workers + priority scoring to process best deals first.

Solution
# Priority queue with auto-scaling
from celery import Celery
import boto3

app = Celery('investment_analysis')

@app.task(priority=1)  # high priority
def process_high_value_deal(deal_id: str):
