What would this note be worth?

[Account Closed]

I am trying to sell an 8-unit apartment building that needs a little work. I am willing to do owner financing since I own it free and clear. The problem is, I would like to get the cash rather than hold the note long term. So, I'd like to create the note, let it season then resell it.

I have an investor interested, but they want to do a no money down deal. I am not crazy about that, but they do have a point that they will be putting money into the building and making the asset worth more. Here are the terms:

Purchase price: $180,000

$0 down payment

6% interest with 30 year amortization, due in 10 years

Payments would be $1,080

So, after all of that, what kind of discount would I expect if I sold the note? How long would the note need to season? I haven't done any due diligence on the buyer, so I am not sure of their credit yet. I will definitely vet them before moving forward, but I want to see if its even worth moving forward.
