Day 6 AI bootcamp: Real Estate Recommendation App

Posted by xkuang on January 3, 2025

Creating a personalized real estate recommendation app leverages the power of artificial intelligence to match users with properties that meet their specific preferences. This guide provides a comprehensive walkthrough on building such an app, incorporating real estate APIs, and enhancing it with interactive maps and data visualization.

Understanding the Integration of AI and Real Estate Data

Developing an AI-driven real estate app involves several key components:

Data Acquisition: Collecting real-time property data using real estate APIs.
User Preference Modeling: Understanding and processing user preferences.
AI and Machine Learning: Implementing algorithms to generate personalized recommendations.
Interactive User Interface: Designing a UI that provides a seamless user experience with maps and detailed property information.

Step-by-Step Guide to Building the App

1. Data Acquisition with Real Estate APIs

To provide users with up-to-date property listings, integrate real estate APIs such as the Zillow API or alternatives like Realtor.com APIand Estated API.

Example of Fetching Data from Estated API:

import requests

api_key = 'YOUR_API_KEY'
endpoint = 'https://api.estated.com/property/v3'
parameters = {
    'token': api_key,
    'address': '1600 Amphitheatre Parkway, Mountain View, CA'
}

response = requests.get(endpoint, params=parameters)
data = response.json()

property_details = data['data']
print(property_details)

2. Incorporating Interactive Maps and Nearby Amenities

Enhance the user interface by integrating interactive maps that display properties and nearby amenities like train stations, schools, grocery stores, and coffee shops with ratings from Google Reviews.

Using Google Maps and Places API:

<!DOCTYPE html>
<html>
<head>
    <title>Real Estate Map</title>
    <script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&libraries=places"></script>
</head>
<body>
    <div id="map" style="height:500px;width:100%;"></div>
    <script>
        function initMap() {
            var propertyLocation = {lat: 37.4221, lng: -122.0841};

            var map = new google.maps.Map(document.getElementById('map'), {
                center: propertyLocation,
                zoom: 14
            });

            var marker = new google.maps.Marker({
                position: propertyLocation,
                map: map,
                title: 'Property Location'
            });

            var service = new google.maps.places.PlacesService(map);
            var request = {
                location: propertyLocation,
                radius: '2000',
                types: ['train_station', 'school', 'grocery_or_supermarket', 'cafe']
            };

            service.nearbySearch(request, function(results, status) {
                if (status === google.maps.places.PlacesServiceStatus.OK) {
                    results.forEach(function(place) {
                        var placeMarker = new google.maps.Marker({
                            map: map,
                            position: place.geometry.location,
                            icon: {
                                url: place.icon,
                                scaledSize: new google.maps.Size(25, 25)
                            },
                            title: place.name + ' (Rating: ' + place.rating + ')'
                        });
                    });
                }
            });
        }

        google.maps.event.addDomListener(window, 'load', initMap);
    </script>
</body>
</html>

3. Displaying Household Income and Demographic Data

Provide investors with insights into the economic landscape by displaying household income data for the property's zip code.

Fetching Data from the U.S. Census Bureau API:

import requests

endpoint = 'https://api.census.gov/data/2019/acs/acs5'
parameters = {
    'get': 'B19013_001E',
    'for': 'zip code tabulation area:94043',
    'key': 'YOUR_CENSUS_API_KEY'
}

response = requests.get(endpoint, params=parameters)
data = response.json()

median_income = data[1][0]
print('Median Household Income:', median_income)

4. Implementing AI for Personalized Recommendations

Utilize machine learning algorithms to analyze user preferences and suggest suitable properties.

Example Using Scikit-Learn for Nearest Neighbors:

import pandas as pd
from sklearn.neighbors import NearestNeighbors

# Load and preprocess real estate data
real_estate_data = pd.read_csv('real_estate_listings.csv')
features = real_estate_data[['price', 'bedrooms', 'bathrooms', 'lot_size', 'year_built']]

# Train the model
model = NearestNeighbors(n_neighbors=5)
model.fit(features)

# User preferences
user_preferences = [[250000, 3, 2, 5000, 2010]]

# Find similar properties
distances, indices = model.kneighbors(user_preferences)
recommended_properties = real_estate_data.iloc[indices[0]]
print(recommended_properties)

5. Designing the User Interface with Advanced Filters

Create a UI that allows investors to filter properties based on various criteria such as bedroom count, bathroom count, lot size, build year, HOA fees, and household income.

Implementing Filters in React.js:

function PropertyFilter({ onFilterChange }) {
    const [filters, setFilters] = useState({
        bedrooms: '',
        bathrooms: '',
        lotSize: '',
        yearBuilt: '',
        hoaFees: '',
        medianIncome: ''
    });

    const handleChange = (e) => {
        setFilters({...filters, [e.target.name]: e.target.value});
    };

    const applyFilters = () => {
        onFilterChange(filters);
    };

    return (
        <div className="filter-panel">
            <input type="number" name="bedrooms" placeholder="Bedrooms" onChange={handleChange} />
            <input type="number" name="bathrooms" placeholder="Bathrooms" onChange={handleChange} />
            <input type="number" name="lotSize" placeholder="Lot Size" onChange={handleChange} />
            <input type="number" name="yearBuilt" placeholder="Year Built" onChange={handleChange} />
            <input type="number" name="hoaFees" placeholder="HOA Fees" onChange={handleChange} />
            <input type="number" name="medianIncome" placeholder="Median Income" onChange={handleChange} />
            <button onClick={applyFilters}>Apply Filters</button>
        </div>
    );
}
