So due to the fact that I am not there to visually see the property up close, it would probably be a good idea to have a contractor give me a quote before I close on the property? 

You can take screen captures. so a visual identity is on record.

Patch walls and replace broken screens as necessary, and fix or replace small things like cover plates for light switches and wall sockets, light fixtures, doorknobs and faucet handles.AppearanceMake the duplex as visually appealing as possible by increasing its curb appeal, the term used to describe how the residence looks from the outside.

I often wonder if people really understand how much money can be made on the commercial brokerage side of this business using the same time and effort one uses to wholesale a house and make a small fee for all your time and effort.. you talk to 100 potential commercial clients and have the same stick to it ness and you would be cashing 6 figure checks not 6k... just food for thought..

One thing I am still seeking is a visual blueprint to run off of.

This one had a spooky feeling basement, but NOTHING visually unusual... until I looked at the photos. 

To maximize your "passive-ness", you should consider aligning yourself with an experienced investor that has been around long enough to have survived a few real estate cycles.

We are visual "creatures" and the professional just has a way of sprucing things up for us!

I think painting them white will have a significant visual impact on the house, allowing us to maximize rents.

The changes are very visually uncomfortable for me.
