How to structure a small partnership for down payment help

[Pablo Mendez]

Brand new to investing, doing reading now. Have been talking real estate with friends and family and family member offered to invest $10,000 with us on our first deal or deals. 

Just finished The Millionaire Real Estate Investor and long term hold rentals will be our focus. 

Plan is to purchase a $100K rental with 20% down traditional mortgage only on my name. 

Do we simply treat the $10K from family as a loan with a fixed rate of return to them? Do we give a percentage of the cashflow and treat it like a partnership? Do we use the $10K to rehab or use it for part of the down payment?
