Long term prospect, how soon is too soon to follow up?

[Daniel Vandenbos]

Hey, BP! First time trying to structure a owner financed deal. Quick story, I was walking by a rental located near my house, found a For Rent sign. Did some research and found the owners are an elderly couple. I reached out to inquire if they would be interested in selling, the wife seemed very happy and we had a great conversation, she advised they were discussing selling. I called back later as agreed to speak with the husband who agreed they have 3 properties they are possibly interested in selling, totaling 7 units...

To the question... They want to wait until spring to do anything, and they took my information and said they will be in contact by the end of the year. Overall I’d say the conversation went extremely well. I set on my calendar to reach out to them the first week of December. In anyone’s experience is this a reasonable timeline? I don’t want to fall out of good graces.... Thank you!
