The people lending you the money will have done numerous deals.  

And still almost 4 month since then, I have asked Nomad numerous times for anything that would help me understand the new tiers and how its different from previous division of responsibilities. 

All the pre-war charm. 

I can't believe your second story  lol , seems like you had a deal in a war zone that is horrible lol! 

Once I hit my reserves goal, I transfer the additional money to a separate "War Chest".

There were at least 4 maybe 5 individuals on Dave’s team that handled numerous things like; getting any necessary info from me and the title company, providing my account statement (proof of funds) for the sellers of my replacement, working with ERG for the exchange documents I needed to sign for both closings, and getting the 45-day form filled out and sent back to ERG.

We've been investing there since 2011 & find it to be a great market IF you stay away from the  war zones.Available to talk if you'd like.Best.

I am newer to this but have done years of research, read books, and read numerous posts on this forum.

So my personal take: If you feel like having a non-contingent offer will allow you to be more competitive and save $10k+ on the new home because of a bidding war/multi-offer situation, then it may make sense. 

Numerous rents How did you find this deal and how did you negotiate it?
