The cause presents in the main only issues of fact wbicb the jury bas determined. The main item of damage claimed by the plaintiffs was the destruction of a store building. The store building bad never been rented out, but the sons of plaintiffs used the building for mercantile purposes with the understanding that the plaintiffs were to have their supplies at wholesale price in lieu of a stipulated rental. On cross-examination the plaintiff was asked whether or not the business bad been prosperous. Tbe plaintiff objected to this question and answer, and excepted to the action of the trial judge in permitting the evidence. This exception cannot be sustained. Rental value of property is competent upon the question of the fair market value of property at the time of the taking. Brown v. Power Co., 140 N. C., 333. If the plaintiffs were to receive a part of the stock of merchandise in lieu of rental, the amount of stock carried or the volume of business would be a circumstance to be considered by the jury in determining wha,t return the plaintiffs were receiving for the property at the time of taking. Plaintiffs further testified on cross-examination that they did not build the building upon the premises; that the building was upon the land at the time they purchased it, about eighteen years ago. Thereupon, the defendant asked the witness what the purchase price was for the entire property. Plaintiff objected to this question. Tbe objection was overruled, and plaintiffs testified that the purchase price was $1,000, but that they bad purchased it eighteen years ago. It is accepted law that when land is taken in the exercise of eminent domain it is competent, as evidence of market value, to show the price at which it was bought if the sale was voluntary and not too remote in point of time. R. R. v. Church, 104 N. C., 525; R. R. v. Mfg. Co., 169 N. C., 156. Certainly the value of property eighteen years before the taking, nothing else appearing, would be incompetent, but upon the present record it appears that the plaintiffs bad testified that they bad owned the property for eighteen years, and that the building was then upon the property. Tbe plaintiffs bad further testified that at the time of the taking the property was worth $3,000. It was therefore permissible on cross-examination to test the accuracy of the opinion of the witness as to the value of the property as well as to demonstrate the basis of bis opinion as to the value thereof. A careful perusal of the record and briefs convinces us that the case bas been fairly tried, and the judgment is affirmed.
No error.
