Statistically speaking, and open house will not help sell your house..  

Many of the statistical/econometric tools I know like the back of my hand are (claimed to be) used regularly in aspects of decision making in real estate. 

@David Cruice, looking at some multi family units in New Mexico, do you have a few tips to pass on to a new investor Possibly some Unknown’s that may come up or what are the most critical things to look for, what % does the city ratings/crime statistics have with determining the value of the investment?

@Ryan Thomas there really is no statistical cap rate in any area.

@James Wise I agree...it's a little difficult to insert metropolitan statistical area after every reference to a city.

Yearly tenant survey wont be useful as im sure you dont have enough data points, ie propertIes, to make it statistically significant.

As long as the numbers are based on the statistical facts and reports (employment, etc).

That graph doesn't show home prices and would be an interesting statistic to compare.

If you want to try an advanced statistical technique to improve your chances of increasing your response rate, research Design of Experiments (DOE), which is a multivariate method of testing many factors simultaneously.
