Small towns like Conneaut, Edinboro, Greenville, and Meadville still have the different neighborhoods but the price variation is a bit tighter. 

There are other variations, but they're variations of these themes.

In Excel you can solve for all different variations of the equation with different variables.

The finish would probably be the area of most variation..

The only reason you have a variation in your set is because the square feet are different amongst units.

Its tough to exactly say but its as simple as people not being able to afford higher payments which would naturally pull housing prices down slightly.Personally, I firmly believe that there should be a greater variation in the interest rate a person receives based on their current financial situation, the LTV the loan is written at, and their credit history.

Is is it not weird that the variation in down payment could be 10% at one, and 25% at another.

Since you're not sure what the name of the color of the original paint was, you're also not certain of the brand of paint and there can be variations amongst the brands even with the same "names" of colors.Most bathrooms aren't very large. 

You're asking how to find the investors in your area who are actively buying properties.So...the answer to #1 is simply to have your realtor pull a report from the MLS of all the recent Cash Sales and see what areas are hot with investors.For #2...Craigslist ads for variations of "We buy houses"..."

I like a variation of @Elizabeth C.'
