My father's justification is that he has no problem lending 50-80 k to me for a 5 % interest.

My father wants to use his SDIRA to provide a loan to the LLC him and I are equal partners in.The loan would provide the additional funds we require to purchase an investment property.The LLC would pay principle and interest at market rate to the SDIRA.Would this be considered a disqualified transaction? 

I was lucky to have a renaissance man for a grandfather and an extremely hardworking father as role models so that helped.

I am a tech professional, but I also own a small Home Improvement company with my father who has been in the industry for 20ish years.

Have a long talk with your father and make sure you can both agree on a plan of action.

Hi,My father purchased this 2-family house (R5 Zone) back in 1976 in Astoria Queens, and just like many other landlords in NYC he rents out the cellar/basement.I've been reading online the definition between a basement and cellar based on the link below, and I think my father's falls under a cellar.

My father bought his first property in 2016 and does it part-time. 

Problem:Currently I own 1/3 equity along with my father 1/3 and our partner1/3.

My father died (again)19. 

My plan is to raise capital for the down payment through an investor and create an LLC with my father to get approved for a DSCR loan.
