DSE 2019 Question 32: Dummy variables and functional forms

Scenario 3: Data from a random sample of 107 home sales in 2003 yielded the regression $\hat P=119.2+0.485\,BD+23.4\,BA+0.156\,HS+0.002\,PS+0.090\,A-35.6\,PC$, with standard errors $(23.9),(2.61),(10.76),(0.011),(0.00048),(0.311),(10.5)$ respectively. $R^2=0.72$, $SER=41.5$. $P$ is price or value (Rs. 1000), $BD$ is number of bedrooms, $BA$ is number of baths, $HS$ is house size (sq. ft.), $PS$ is plot size (sq. ft.), $A$ is age (years), and $PC$ is a dummy $=1$ if the house is in poor condition and $0$ otherwise.

What is the loss in value if a homeowner allows his house to get into 'poor condition'?
