Real Estate Portfolio Management

Automate portfolio tracking, performance monitoring, and valuation updates across your entire real estate holdings with unified data from 20+ global platforms.

The Portfolio Management Challenge​

Managing a real estate portfolio involves tracking dozens or hundreds of properties across multiple markets, each requiring constant monitoring.

Manual Data Collection​

  • Logging into multiple portals to check property values
  • Copying data into spreadsheets for each property
  • Hours spent updating portfolio metrics each month
  • High risk of human error in data entry

Delayed Valuations​

  • Waiting weeks for professional appraisals
  • Outdated portfolio values affecting investment decisions
  • Missing market opportunities due to slow data updates
  • Difficulty justifying valuations to investors or lenders

Fragmented Market Intelligence​

  • No unified view of portfolio performance across markets
  • Cannot easily compare properties or identify underperformers
  • Limited visibility into local market trends affecting each asset
  • Challenging to forecast future portfolio value

Inefficient Operations​

  • Cannot track rent comparables for all properties simultaneously
  • Manual monitoring of new listings near portfolio properties
  • Time-consuming portfolio reporting for stakeholders
  • Difficulty scaling portfolio management as holdings grow

Limited Competitive Intelligence​

  • No systematic way to track similar properties for sale
  • Missing acquisition opportunities in target markets
  • Cannot benchmark portfolio performance against market
  • Incomplete data on neighborhood dynamics

How It Works​

Track Portfolio Valuations​

Monitor property values across your entire portfolio:

from propapis import PropAPIS

api = PropAPIS(api_key='your_api_key')

# Define portfolio properties
portfolio_addresses = [
    '123 Main St, Austin, TX 78701',
    '456 Oak Ave, Nashville, TN 37201',
    '789 Pine Rd, Denver, CO 80202'
]

# Get current valuations
for address in portfolio_addresses:
    property_data = api.platforms.zillow.get_property(address)

    print(f"\n{property_data.address}")
    print(f"  Current Value: ${property_data.zestimate:,}")
    print(f"  Last Sale: ${property_data.last_sold_price:,}")
    print(f"  Value Change: ${property_data.zestimate - property_data.last_sold_price:,}")

Monitor Performance Metrics​

Track key performance indicators for each property:

# Get detailed property metrics
property_data = api.platforms.zillow.get_property('123 Main St, Austin, TX')

# Calculate performance
current_value = property_data.zestimate
purchase_price = 450000
appreciation = current_value - purchase_price
appreciation_pct = (appreciation / purchase_price) * 100

print(f"Purchase Price: ${purchase_price:,}")
print(f"Current Value: ${current_value:,}")
print(f"Appreciation: ${appreciation:,} ({appreciation_pct:.1f}%)")
print(f"Rent Estimate: ${property_data.rent_zestimate:,}/month")

Compare Rental Income Potential​

Optimize rental rates across portfolio:

# Get rent comparables for portfolio property
rent_comps = api.platforms.zillow.search_rentals(
    location='123 Main St, Austin, TX',
    radius=0.5,
    bedrooms=3,
    bathrooms=2,
    status='active'
)

# Calculate market rent range
rents = [comp.price for comp in rent_comps]
avg_rent = sum(rents) / len(rents)
min_rent = min(rents)
max_rent = max(rents)

print(f"\nRent Comparables (n={len(rent_comps)})")
print(f"  Average: ${avg_rent:,.0f}/month")
print(f"  Range: ${min_rent:,} - ${max_rent:,}")

Monitor market conditions affecting portfolio:

# Get market trends for portfolio locations
markets = ['Austin, TX', 'Nashville, TN', 'Denver, CO']

for market in markets:
    trends = api.platforms.zillow.get_market_trends(location=market)

    print(f"\n{market}")
    print(f"  Median Price: ${trends.median_price:,}")
    print(f"  YoY Change: {trends.yoy_change:.1f}%")
    print(f"  Days on Market: {trends.avg_dom:.0f}")
    print(f"  Inventory: {trends.active_count:,} listings")

Identify Acquisition Opportunities​

Find new properties matching portfolio criteria:

# Search for acquisition targets
targets = api.platforms.zillow.search_listings(
    location='Austin, TX',
    property_type='Single Family',
    min_bedrooms=3,
    min_bathrooms=2,
    max_price=500000,
    days_on_market_min=60,  # Properties sitting longer
    status='active'
)

print(f"\nFound {len(targets)} potential acquisitions")
for prop in targets[:5]:
    print(f"  {prop.address} - ${prop.price:,} ({prop.days_on_market} DOM)")

Quick Start​

from propapis import PropAPIS

api = PropAPIS(api_key='your_api_key')

# Track a portfolio property
property_data = api.platforms.zillow.get_property('123 Main St, Austin, TX')

print(f"Address: {property_data.address}")
print(f"Current Value: ${property_data.zestimate:,}")
print(f"Rent Estimate: ${property_data.rent_zestimate:,}/month")
