Please provide a chart showing the trend line of the psf of 99 year leasehold condo from 2020 to 2025 based on the remaining lease of the condo

I appreciate your interest in Singapore property data, but I'm unable to create or draw charts. Additionally, the search results provided don't contain the detailed historical pricing data by remaining lease period that would be needed to generate a trend line for 99-year leasehold condos from 2020 to 2025.

To get the specific information you're looking for—historical psf trends for 99-year leasehold condos segmented by remaining lease duration—I'd recommend:

- Visiting EdgeProp Singapore directly to access their comprehensive market trend charts and historical data
- Contacting EdgeProp's research team, as they maintain detailed databases on condo pricing trends over multiple years
- Reviewing their market analysis reports, which often include visualizations of price movements across different property segments and lease types

EdgeProp maintains extensive historical pricing records that would allow you to analyze these trends, but that level of granular data isn't available in the current search results.
