We develop and consult new developers through the full cycle of development.Financing differs from project to project based on your equity, land cost, construction methods, etc.

I'm sure there will be others with their own (and possibly conflicting) opinions, but for question #1, I always advise my clients to focus on properties in areas that 1) they currently (or previous) live in/near, 2) they travel to frequently, or 3) they have family/friends in the area.For question #2, the answer is going to depend on what you do for #1.

Considering traveling nurses/workers, as well as seasonal rental for ND home games (also a huge Fighting Irish family).

My agent is currently finding best rates with Travelers.   

A place that is easy (and hopefully) inexpensive for you to travel to a couple times per year to check in on things.  

We also use Travelers and Proper.

But consulting with the town would be good to try to understand what they're permitting process is like.

Second question is, if we don't live in the city we will invest in, we understand we will have to be traveling often, but who could be a good person to check in on the construction so we don't have to go every week?

If the signs point to selling, consult your CPA about the tax implications.
