Excellent, you took initiative and did something very difficult for most people.  

Just remember, while initial cash flow might be lower, Denver's still a hot spot for long-term appreciation, and its rental demand means you shouldn't have trouble finding tenants.

Of course I still need to decide which part of the country I plan on investing in (it's possible I'm moving around the country frequently in the first year, so that is making me think about the most ideal location for an initial investment).Once established and with a track record in Spain, I plan on making my first investment here in the US, most likely in the Boston/MA area.In any event, I'm excited to connect and learn from those in this group.If you know anyone with international investment properties or contacts abroad, especially in Spain, I would love to connect!

My initial read of your post makes me think you're over-analyzing this.Pick a couple areas and go visit...you'll know when it feels right.

This initial build is funded by my cash and equity in personal residence.

Alas I was dumb enough not see initially.

I think I've probably passed the deadline by now but I thought I saw somewhere on the website mentioned that I can submit the document after the initial appeal has been submitted?

Their Hartford quote is also well above the price my own agent had gotten me from Hartford and at least initially appears to be identical coverage.  

However, I've encountered a setback as my initial lender has withdrawn (100%LTV), necessitating the search for alternative financing.

I told my initial lender my plan.
