The correlation coefficient came in at 0.03.

Scientific method, coefficient of expansion, gravity, etc  all of your technical background applies to investing and wealth management.2.  

See, it's a snazzy start-up where everything is remote (besides their main office in SF) and they got da fancy "algorithms" & da nifty "machine learning" with a coefficient quadratic equation here and a pythagorean theorem there that tells them what rent should be and tenant profiles you should look for.

Get rid of all the technical Math discussion on the house, I don't care about Fibonacci or the Coefficient of Expansion if that was included. 

To pick just one of those items and call it "investing" is not understanding the element of time/energy coefficient.

California's GINI coefficient is on par with many third world countries. 

NCREIF Real Estate Correlation to:Russell 3000 Index: 0.23Barclays US Aggregate: -0.24NAREIT: 0.13A correlation coefficient of 0 means that price fluctuations are not correlated at all.

One way to quantify income inequality is with the gini coefficient.

If it intimidates you, don't worry, I will attempt to be concise and provide a laymens terms summary.Basic statistics crash course:Obtain as many sample rent data as possible (Zillow works)Define alpha for null hypothesis testing ( 0.05)Run multiple regression analysis (#bed, #bath, sq ft) against active rental list prices.Observe P-values for each metricResult:#Bed - 0.02#Bath - 0.04Sq ft - 0.02All are below or equal to 0.05, reject null hypothesis (statistically significant).Create multiple regression line using coefficients for each metric.Input variables from project property and solve for rent!

Rehab Construction:R-19 or higher wall insulation (except for in the Deep South)Insulated sheathing or right foam boardIf the walls aren’t T-19, HVAC should be SEER 14 (at least) and 95% AFUENew Construction:R-19 or higher wall insulation.High quality windows such as Energy Star, U-values (in the North), and Solar Heat Gain Coefficients (in the South)Who can claim the tax credit?
