Answer
There is a reason to be concerned with multicollinearity.
Work Step by Step
In MINITAB, enter the Acres values in C1, the Bedrooms values in C2, the Bathrooms values in C3, the Sq. ft. values in C4, the Age values in C5, the Rooms values in C6 and the price values in C7.
Select Stat -> Basic Statistics -> Correlation
In variables enter C1 C2 C3 C4 C5 C6 C7. You may deselect "Display p-values"
Click OK.
Since some correlations between the explanatory variables are greater than 0.7, there is evidence that multicollinearity exists.
