But I think changing demand patterns from young buyers and renters have the potential to turn these areas into very vibrant and valuable communities - like they historically were.

The pattern (whether we like it or not) has been for agents to list below where they actually think it will sell to get multiple offers.

You will begin to see a pattern here and you will soon learn what finishes are necessary in your market and corner lots on a busy street sell for less :).

Colors clash, patterns clash, and honestly it looks so ugly it's like the sellers are still living in the home.The seller is not happy.

Research these areas and you’ll see a pattern.

Again, paying $100 o whatever for every time the tenant see a roach or a mouse, is dumb in the long run....again, your PM should know that....Some or all of these could be legit....but when there is a pattern, you need to get to the source of the pattern and stop the bleeding, not put a band aid over it.

Do you have an idea on laundry usage patterns across all of your properties?

After enough time is spent on the MLS, or even a site like Zillow, I think that you develop an idea of the base cost of a house that you're looking for, and after enough evaluations, you'll start to notice patterns in the numbers (of the listing, not the analysis) where you could then decide to run a more in-depth analysis.

As for credit score,  I don't rely on set number but more importantly patterns that show up on the credit report. 

@Chris Hanisco - think about the $400-600/mo you won't be able to spend on your son and yourself because you're being charitable to someone who has shown a pattern of not respecting the property you are purchasing.
