$Cumulative~relative~frequency=\frac{cumulative~frequency}{sum~of~all~frequencies}$
Total (sum of all frequencies): $4+13+19+7+3+2+1+0+1=50$ houses.
The cumulative relative frequency for "50,000–99,999" is $\frac{4}{50}=0.08$
The cumulative relative frequency for "100,000–149,999" is $\frac{17}{50}=0.34$
The cumulative relative frequency for "150,000–199,999" is $\frac{36}{50}=0.72$
The cumulative relative frequency for "200,000–249,999" is $\frac{43}{50}=0.86$
The cumulative relative frequency for "250,000–299,999" is $\frac{46}{50}=0.92$
The cumulative relative frequency for "300,000–349,999" is $\frac{48}{50}=0.96$
The cumulative relative frequency for "350,000–399,999" is $\frac{49}{50}=0.98$
The cumulative relative frequency for "400,000–449,999" is $\frac{49}{50}=0.98$
The cumulative relative frequency for "450,000–499,999" is $\frac{50}{50}=1$
