I think it is one of the most important questions you can ask.
Understanding how your asset will be maintained after you complete will determine many things, such as: the ease of rental, how enjoyable it will be to live within the community of the building, what rental return you will get as compared to other buildings within close proximity. In fact, I believe this question tells you more about the developer and how you can protect your asset and funds than any other question. So, find out all you can by asking questions like; who is managing my property? What have they built and how are those buildings being run? What fees will I be paying and what service are included?
