I paid about $2000 an acre for a 5 acre lot back in 1976 and that was considered too high. A lot about 1/2 mile from me sold for $300,000 this past fall, and it didn't have tree on it. Back in1970 or so, I should have bought that 160 acres east of Albuquerque for $28 /acre.
God isn't making anymore land and it will only continue to rise
Around here where it took 30 acres or so to run a cow/calf pair, they are raising houses 8 to an acre and selling them for $300,000 base.
There isn't a farm or ranch, if you can call one that, within 20 miles of me now over 40 acres.
