Hajjar was running out of money to finish homes under construction on Osmond when the Herzogs negotiated their purchase. They had previously been interested in 251. While floor plans were mostly the same, 257 had an open atrium inside the entrance the full height of the house. This diminished the floor space enough that there was not room for Lisa's dining set.
The Herzogs had enough bargaining power that Hajjar enclosed the atrium in order to make the sale. Lisa feels that Hajjar never really got over having to make the change. Leonard reports that when he and Hajjar went to the bank to arrange for a mortgage, then normally staid First National Bank president John Truby jumped up on his desk, did a little jig and exclaimed, "So you're the one who is going to bail Hajjar out this time!"
