40 people times 1900 per month is 76,000 per month, 912,000 per year.
Usually for real estate back of envelope calculations, 120 months or 10 years' worth of rent is what the value of the property is. What did the Negev property sell for?
It seems in the bay area that figure isn't accurate. From my experience the term is even greater than 150 months, often more than 200. I guess this means rent is cheap here (or conversely the price to buy is very high, probably partly because mortgage rates are so low and the interest is tax deductible).
