What would be a fair percentage for a partner just to cosign?

[Ricardo Mejia]

I'm a software developer with two full time jobs and have been saving 70% of my income for the last year. I want to get a duplex that needs a small to moderate amount of reparations to house hack with an FHA loan. Unfortunately, I'm 6 months away from having a full 24 month work history at my job since I'm just starting out my career.

I could wait the 6 months but I've been seeing a few good deals in my market that would be good to jump on. I have the full downpayment and closing costs and would be managing the entire process. For this I will need to find a partner to cosign with me.

What would be a good percentage split for my partner if all they're doing is just cosigning on the loan?
