| Location / Type | Price per Rai | Notes |
|---|---|---|
| Ban Pong (housing dev land) | ฿850,000 | Large plot, inland |
| Khung Phayom (river/canal view) | ฿302,400 | 2,772 m² plot, distant river view |
| Chom Bueng (mountain view) | ฿400,000 | Panoramic mountain, not river |
| Mueang Ratchaburi (provincial capital) | ฿1,668,800 | Urban district, median |
| Photharam (Mae Klong riverfront resort) | ~฿18,400,000 | Prime riverfront, small plot, resort zoning |
| Your Deal (proposed) | ฿2,000,000 | Riverfront, 2 rai — verify exact frontage |
Riverfront land commands a significant premium. The Photharam comparable shows prime Mae Klong riverfront can exceed ฿18M/rai for small resort plots. Your ฿2M/rai is reasonable if the river access is secondary or the plot is larger and less developed.
Your effective price: ฿1,250 / m² — competitive against provincial averages but verify exact river frontage quality.
Based on historical regional growth (~5.5% CAGR), infrastructure developments (M8 motorway, highway upgrades), and riverfront scarcity premium, here are three scenarios over 5, 10, and 15 years:
Assumes slower growth, economic headwinds, minimal development.
| 5 years | ฿4.64M (+16%) |
| 10 years | ฿5.38M (+35%) |
| 15 years | ฿6.23M (+56%) |
Matches 10-year historical regional trend. Most likely baseline.
| 5 years | ฿5.24M (+31%) |
| 10 years | ฿6.87M (+72%) |
| 15 years | ฿9.00M (+125%) |
Strong infrastructure spillover, tourism growth, riverfront premium.
| 5 years | ฿5.88M (+47%) |
| 10 years | ฿8.64M (+116%) |
| 15 years | ฿12.69M (+217%) |
At ฿2M per rai for riverfront land, this deal is fairly priced to slightly undervalued assuming the land has genuine river frontage, good road access, and a clean Chanote title. The 10-year regional trend of ~5.5% annual growth supports a positive outlook, and the upcoming M8 motorway is a meaningful catalyst. However, flood risk and title verification are non-negotiable due diligence items before proceeding.
