By the Court, THOMPSON, C.J.:
The State commenced separate actions in eminent domain to condemn property owned by Andrea and Maria Tacchino. The actions were consolidated for trial and the jury returned its verdict for $396,402.28 in one case, and for $182,976.98 in the other. By this appeal the Tacchinos contend that the district court committed prejudicial error when, by pretrial order, it precluded them from offering certain evidence bearing upon fair market value. In our view the preclusive ruling should not have been made, and since it strikes the very heart of the cases, we reverse the judgments and remand for a new trial. Other assigned errors need not be considered.
The property to be condemned consists of all of Blocks "A" and "D" comprising 9.838 acres, and a portion of Block "E" comprising 4.205 acres, and is located within the Tacchino Industrial Park. The property is zoned M-1 which is industrial type zoning and may be used for almost any purpose except single family residences. The Tacchinos acquired the property many years ago and used it as farm land. In 1953 they decided to subdivide their property and contacted the Regional Planning Commission and were assisted by one of its staff in the preparation of a tentative map for subdividing the property into lots. An engineer-surveyor was then employed to prepare a tentative plat of the subdivision showing boundaries, topography, streets, blocks and lots. That plat was approved by the Regional Planning Commission in April 1954. A final subdivision map was then prepared for recordation. It received the approval of the Commission and the City of Reno and was filed with the County Recorder of Washoe County on January 15, 1955. Streets have been cut and graded, and some sewers and storm drains installed. The highest and best use of the property to be condemned is conceded to be for industrial purposes.
The Tacchinos wished to show the value of the condemned property on a lot basis which would have established a higher market value than that shown by evaluating the property as a whole. That approach to the ascertainment of value was ruled out by the district court as to speculative and conjectural. It is to this point that we address this opinion.
1. Private property shall not be taken for public use without just compensation having been first made or secured. Nev. Const. art. 1, § 8. The word "just" is used to intensify the meaning of the word "compensation" and conveys the idea that the equivalent to be rendered for the property taken shall be real, substantial, full and ample. Virginia and Truckee R.R. Co. v. Henry, 8 Nev. 165, 171, 172 (1873); Urban Renewal Agency v. Iacometti, 79 Nev. 113, 128, 379 P.2d 466 (1963); Dep't of Highways v. Campbell, 80 Nev. 23, 32, 388 P.2d 733 (1964).
In line with this underlying concept we have ruled that pre-judgment interest must be paid to the condemnee when the taking occurs before judgment. Saunders v. State, 70 Nev. 480, 485, 273 P.2d 970 (1954). And, in State v. Shaddock, 75 Nev. 392, 398, 344 P.2d 191 (1959), the court wrote: "In determining value and just compensation, evidence of the market value of the property taken is properly received. This is conceded by both appellant and respondents. That this is so does not preclude the court or jury from considering other elements that can fairly enter into the question of value and which an ordinarily prudent business man would consider before forming judgment in making a purchase." The standard just quoted was reaffirmed in Clark Co. School Dist. v. Mueller, 76 Nev. 11, 19, 348 P.2d 164 (1960), a case where the trial court received per-lot appraisal evidence of residential property concerning which preliminary engineering work had been done looking to a formal subdivision.
One inevitably must conclude that the constitutional command for the payment of just compensation can be obeyed only by assuring the property owner that our courts will receive all evidence fairly bearing upon value.
In Almota Farmers Elevator Whse. Co. v. U.S., 409 U.S. 470 (1973), the question was: "Whether, upon condemnation of a leasehold, a lessee with no right of renewal is entitled to receive as compensation the market value of its improvements without regard to the remaining term of its lease, because of the expectancy that the lease would have been renewed." Held: The concept of "just compensation" is measured by what a willing buyer would have paid for the improvements, taking into account the possibility that the lease might be renewed as well as that it might not. The Court of Appeals decision was reversed because it failed to recognize the possibility of a renewal of the lease; a factor which a willing buyer would have considered.
Our Nevada decisions are, we think, in harmony with the philosophy of the Almota case.
2. The State pursuaded the district court that expert witnesses should not be permitted to arrive at their opinions of the fair market value of the property by carving it up into lots, estimating the value of each lot, and then estimating the value of all lots together. This, because valuation must be based upon what a willing purchaser will pay for the whole at the time of the taking and not on what a number of purchasers might be induced to pay in the future for the land in small parcels.
There is solid support for this rule when the land is undeveloped and the subdivision is imaginary or hypothetical. Department of Highways v. Schuloff, 445 P.2d 402 (Colo. 1968). Indeed, some courts so limit expert testimony when the owner has had a subdivision plat prepared or filed for record, or has been systematically developing the tract in parcels or units. City of Caldwell v. Roark, 437 P.2d 615 (Idaho 1968), and Continental Development Corporation v. State, 337 S.W.2d 371 (Tex.Civ.App. 1960), are illustrative.
In our view, those cases and others from several jurisdictions applying the same rule, improperly restrict and limit testimony of qualified appraisers, and are not compatible with the conceptualistic expressions of our court in Virginia and Truckee R.R. Co. v. Henry, Dep't of Highways v. Campbell, State v. Shaddock and Clark Co. School Dist. v. Mueller, to which we have already referred.
A qualified witness should be allowed to testify to the different factors which a well-informed buyer would use in arriving at a price he would pay for the land. Iske v. Metropolitan Utilities District of Omaha, 157 N.W.2d 887 (Neb. 1968). The potential income to be derived from the sale of subdivided lots, properly discounted to show present value, is a factor and relevant to a determination of market value, since sophisticated investors make decisions on the basis of income capitalization. Dash v. State, 491 P.2d 1069 (Alaska 1971); Iske v. Metropolitan Utilities District of Omaha, supra; In re Appropriation for Hwy. Purposes of Lands, 239 N.E.2d 110 (Ohio App. 1968); State Highway Commission v. Lee, 485 P.2d 310 (Kan. 1971). The reasoning of these cases accommodates the constitutional concept of just compensation and tends to assure the property owner that he will receive a full and fair trial of that issue.
Reversed and remanded for a new trial.
