Land contract vs lease option when a tenant/buyer is refinancing

Does one offer more opportunity for the tenant to refinance than the other?

Is either a LC or LO considered a refinance in the eyes of the lender?

Does the term of the LO or LC affect the tenants ability to refinance (1 year vs 2 year option)?

Does the amount of the option or down payment affect the tenant’s ability to refinance?

I would like to get the tenant in the best position possible to make the purchase more likely than not. Thanks!
