Need some help with what data to use.

[Kosebaja]

Hello there!

Im kinda new to EViews and econometrics, but I am having a great time learning about it. This semester I am finishing my degree in macroeconomics and I choosed to write about real estate prices.

I have had some courses in econometrics before that went very good, but its a whole new world when you have to find all the data yourself.

My dependent variable is:
- Real estate prices in square meters

The undependent variables:
- The unemployment rate
- Number of people living in the city (I am using log on this variable)
- Interest rate on bank loans
- Number of houses in the city. (I am using log on this variable)

Its a time series analysis and ill find the unemployment rate and the interest rate to be stationary.

The number of people and number of houses are only stationary in first difference.

So when I run my OLS I get non significant variables.

I've been reading around this forum for some time now and I suppose my problem are that my variables are cointegrated.

Ive also been using the Hodrick Prescott filter to get the trend and cycle to all the variables, can I use the cycles and try to estimate a regression line? If not, what is the use of the HP filter?

Thanks for taking the time to read this.
