"Across the room assessment"

[Eric Brewer]

What's up guys, newbie here to the real estate investing world. I wanted to get some opinions from the old and new investors out there about what are the first things they look at on a MLS report or any other real estate website (realtor.com, Zillow, etc). What makes up your "first impression". What are some of your hard stops when looking at the house details (price, square footage, price/sqft, neighborhood, etc.) What are your absolute H-to-the-no's and what are somethings you see that push you to explore more on that property. I know these are very general questions but for me I am in a very unique position where I can explore a lot of different types of houses and scenarios so I will take whatever feedback I can get. My exception would be, it would have to be my "primary residence" since I am a first time home buyer.

I am an emergency room nurse and one of the skills I have developed over time is to determine if a person is "sick or not sick" by being able to look at the patient from across the room and make a decision. I'ts call our "across the room assessment" and nurses have that skill dialed in. I want to utilize that skill when I look online and really dial it in. I want to be able to tell from across the room if a house is "sick or not sick" just by looking at the initial listing. 

I've been plowing through all these resources and find myself getting a little overwhelmed looking at house after house after house trying to find a good deal. I feel like at some point everything just looks the same.

Thanks in advance for any and all feedback...
