How long do I have to hold a note before I sell it?

[Alettia Rucker]

After hearing a guru on note selling I decided to reverse engineer a deal. I have an end buyer that's a 100% Vet makes $5000 per month from benefits. He has $10,000 to put down. He's old school so he hasn't thought to establish credit and he doesn't have any other bills. I found a home to purchase for him.

ARV - $130,000

Purchase price - $79,000

Repairs - $5,000 (this light because the buyer is fine with it how it is but I want to make sure that its up to par)

Note:

Purchase price- $100,000

Downpayment - $10,000

Interest - 11%

10 years/ 120 payments

Monthly payment: 1377.36

I have a MLO lined up and a servicer

If I get a Hardmoney loan to purchase and rehab the property how soon can I get out? How long do I have to hold the note before I can sell it? Where do I find the note buyers?

Is this even the right exit strategy? Also, one other concern is the home that he likes has an above-ground pool. Will I need additional insurance for this?

Any insight would be helpful.
