I'm wondering how significant this is overall regarding resale, and whether I should adjust the MAO to be lower than 70% to accommodate the location--or expect a lower ROI at sale.

depends on location, in a city they should be within .5 mi, in a suburb 1 mile and rural  5 miles but unique properties can be stretched further, I have done thousands of BPO's for banks, the rules were 3 listed and 3 solds, within 20% speck and similar condition, and make appropriate adjustments for differences, there is more art than science to it.

I’ve started the insurance claims and the adjusters are starting to arrive, but I can’t figure out how to connect the adjusters with my PM.

All of the other fields (criteria) that a service like listsource offers are abstracted (manually entered by a person looking at the document).

Also regarding the CapX, I do not completely understand how that works or is adjusted.

What I'm learning is that the manual method seems to work fine for you guys...

The deal is working for us at our original numbers, so I'm inclined to follow your advice and not to make any adjustments upwards.And I agree, two leases does not make prove a market. 

I need a mental adjustment and I need someone to tell me how it really is.

You can plug all your numbers into the brrrr calculator and quickly see where your investment stands and how to adjust things to make the numbers work.  

Rental criteria and terms of agreement can be adjusted to fit the market.
