Johanna called. Said that she called the guy who wanted to be kept posted, and he offered a bit higher than me, but she really wanted to sell to me. I immediately offered $315,000, and she said she had to call her Dad.
She called back about a half hour later and said, "Congratulations, your the soon to be owner of beautiful apartment in Manhattan." We talked a bit about furnishings, and I gave her $150 for the mattress and the office chair.
So I'm very pleased with this development. I emailed her my attorney's info, and contracts should be drawn tomorrow.
