I recently did some research on this. Phnom Penh has a lot of great options, especially in new residential complexes. You should definitely check out the World Estate website for a detailed list of available apartments. They only work with trusted developers, which is a big plus. You can find their listings here: https://worldestate.homes/en/cambodia/flats/. Prices vary widely, starting from around $74,176 for projects like R&F City Residential Complex. Be sure to check the completion dates and developer reputation. A good lawyer is essential to navigate the legal process, especially since the laws for foreign buyers can be tricky. Good luck!
