Personally speaking I thing LI is super over valued and there's a ton of traffic.

Unlike most properties in that area, this duplex is on a small gravel private road by a canal so there is no thru traffic and a lot of privacy.

Sounds like little house on the prairie but Wait till a chicken gets loose (as they always do ) and stumbles out in traffic ( as they often do)  .

I haven't seen a lot of traffic on the forum for Oahu.Any advice is much appreciated!

I/we don't want to be in huge cities (we're early 40s and value quality of life vs crazy traffic), but want to be proximate to options and accessibility. 

The professionals needed for development include lawyers, engineers including civil, geotechnical, environmental, and traffic, architects, title companies and surveyor.I may be telling you what you already know and I could go on and on but it would be easier to discuss one or two areas rather than explain all of them.

Check to see if you have to install any manholes, fire hydrants, curb, gutter, sidewalks, street signs, street lighting any specific street design or access requirements, Check DOT requirements for access, stop lights and permits, traffic studies, DWQ requirements for permits, permit fees and time frames.Once you have an idea of what you can build and what is required in terms of permitting and infrastructure you want to talk to some civil engineers, architects and commercial general contractors that do the type of projects and build the type of buildings you want to build so you can get an idea of costs, time frame and requirements.

We prefer flexible for that reason (and because, as @Luke Carl mentions it seems to be preferred by ABB) but sites like "booking.com" offer a non-refundable rate option that can also boost traffic and bookings.The key is that you're happy and comfortable with your policy and "enforcing it" if need be.

And remember the traffic in NYC is brutal .

Imagine spending 1.6 mill and there is a traffic jam in front of your house, and NO garage, you are parking on grass.
