Politics/Bureaucrats -- what laws are in place to prevent you from deploying in X fashion? Can you bury fiber? Do you have to string across utility poles? If so, who owns the poles? (It'll either be the city or a utility company) What are their rates? What are the requirements to get quotes for their rates? (CenturyLink requires you to be a part of an NDA/Non-Compete Agreement program if you are reselling competitive services)
Business -- how many people are you looking to service? What's the absolute max you could potentially service? (usually subdivisions are zoned with a specific max amount of households) How many would you like to service? What is an acceptable cost? (I found $100 is the sweet spot for gigabit fiber) What kind of customers will you be servicing? (mostly soccor moms who will browse the internet from 11a-3p, young families who embrace video streaming from 8p-11p, retirees who only care about email and facebook from 9a-12p, etc.)
Technical -- how much bandwidth do you really need? Chances are you can actually service 100 or so residential customers with just a single gigabit ethernet connection. How much fiber will you need to run to everyone? The easiest thing to do is run single-mode fiber connected to a media converter in their house. Depending on how you can do "huts" (as google has dubbed them) you will probably do single cisco ToR switch with 48 spf+ ports for 40 customers. You will dedicate 4 ports for uplink connectivity via LACP and have 4 stand-by ports should one be bad. Scale this out as needed.
This will also be specific to your area -- but expect $10k/mile to run conduit to a hut with an additional $2k/mile for different fiber pulls. You would usually run conduit and some kind of fiber at the same time -- probably 96 strand single-mode. But that's up to you.
Not sure what else you need to know. That should be a good starting ground. The bulk of our capital was for fluid insurance bonds. About 80% of our working capital was going to be tied into those while we laid the fiber.
