accordingly , i vote for limiting the increase in compensation to be awarded to defendant appellants to the valuation set by themselves as owner in the amount of p300,000.00 with 6 % interest per annum on the balance of p200,000.00 from may 4 , 1963 , which would bring the total exproprriation value to close to five hundred thousand pesos ( 500,000.00 ) or ten times the original price paid therefor by defendants-appellants .
