Identify a good HDB block with the highest rental yield and lowest purchase price.

To identify a good HDB block with high rental yield and a relatively low purchase price, you can utilize several tools and resources available on EdgeProp Singapore.

1. Market Trends Tracker: This tool allows you to access historical property data and compare sales volumes of similar properties. You can filter the data to focus on HDB blocks with higher rental yields and lower purchase prices.

2. HDB Lease Tool and Affordability Calculator: These tools can help you calculate the HDB tenure and affordability, ensuring you find a block that fits your budget.

3. Property Alerts and Search Filters: You can set up property alerts and use search filters to find HDB blocks near amenities like MRT stations, schools, or within specific HDB estates or districts. This can help you identify areas that are likely to have higher rental demand and thus better rental yields.

4. Heatmap: The heatmap feature on EdgeProp Singapore shows the most popular property sales locations, which can indicate areas with high demand and potentially better rental yields.

Some general tips:
- Look for HDB blocks in mature estates that are close to amenities but may not be in the most central or expensive areas.
- Consider blocks with recent renovations or upgrades, as these can attract higher rental income.
- Use the historical data to identify trends in rental yields and purchase prices in different HDB estates.

By combining these resources, you can make an informed decision on which HDB block offers the best balance of high rental yield and low purchase price.
