Having lived nearly 15 years in Shanghai and been deeply interested in both Shanghai history (with this blog), architecture as well as in French real estate for expatriates (with my own firm EXPATRIMO), it is natural that people came to me about Old Shanghai real estate.
Old Shanghai Villas and pre WW2 apartment buildings are a very specific market with its own rules quite different from usual Shanghai real estate. I partnered with one small firm dedicated to it and having been in operation for many years. I consider them the most knowledgeable people on this topic in the city.
If you want to buy or sell Old Shanghai real estate (pre WW2 only!), of if your want to rent out one of those properties, we can surely help you. Please do not hesitate to contact me at: hmartin_at_shanghailander.net
