What questions should I ask when interviewing an architecht?

[Will Wu]

I recently engaged into negotiating the purchase of a lot in Miami that is zoned for building 2 multi-families fourplexes. The developer sold me 3 fourplexes a year ago and offered me this vacant lot to built additional 2 if I wanted. I've been very happy with the high cap rate of the fourplex as well as the 20% valuation of the properties in one year. I'm totally new to construction, the developer is a gentleman on his 70's and he retired last year and has no wish to engage into another construction project. He will introduce me to his architects and builders so they can walk me thru the whole process. I have no experience whatsoever in buying lands and constructions. I'm hoping any developers can give me tips on what I should be aware of and what questions should I ask when interviewing the architects/builders?
