let's assume you require ,say, 20 gallons per minute flow to your home.
for 3/4" pipe: pressure loss at the end of 700' pipe is about 38 psi due to friction. So if the main header has 60 psi where your pipe connects, you will see about 12 psi at your home. This is assuming the 700 feet is not on an incline, which will reduce pressure even more.
using this same concept:
1" pipe -- about 11 psi lost in the pipe.
1.5" pipe -- about 2 psi lost in the pipe.
2" pipe -- about 1/2 psi lost in the pipe.
I don't actually know your flow requirements. Flows higher than 20 gpm will cause higher losses. I would suggest the 1.5" pipe to allow for outside water usage inside and outside at the same time.
