After the Continuation War ended in 1944, parts of Kirkkonummi were rented by the Soviet Union to host a military base, and Eri-Aaroni was evacuated again. He ended up in Porvoo, and finally in Nastola. From his time in Åland, he had sired about 300 foals. In 1946 the horse breeding association of Laihia made an offer to purchase him from Buttenhoff, despite the fact that the horse population in Laihia was already widely influenced by his sire, Murto. Buttenhoff agreed to sell as he had become disabled by rheumatoid arthritis, and Räikkönen, the groom and trainer of Eri-Aaroni, was planning to become a farmer. Multiple horse breeding associations had expressed interest to purchase the stallion, but Buttenhoff chose to sell to Laihia because he heard the mare population of Laihia was of high quality. Eri-Aaroni was sold for 2 000 000 Finnish marks, corresponding to c. 680 000 Euros. It was the highest price ever paid for a horse in Finland.
