Can I invest through primary residence co-owner loan?

[Sarp Ka]

Hi there,

If i agree with my friend and we split closing costs 50-50, could I own 50% of the house and can my friend still get primary residence conventional loan with 10-15% downpayment?

Please note that I cannot get any primary residence loan since I'm already using one and it hasn't been 1 year since I've closed on my property. However my friend can get a primary residence loan and can live in that property.
