Private money finances 25% and gets equity

[James Schiro]

I am considering a financing arrangement and would like thoughts on whether this makes sense.  

I have identified an apartment complex that will have slight + cash flow with conservative expense/revenue estimates and 100% financing. 

I have an investor partner who will finance 25% at market or slightly below market rate on an 8 year am. 75% will be financed via conventional commercial financing, 20 year am. with 5 year balloon. 

In return for providing all of the "come up money", the partner would receive 25% ownership stake and, as I mentioned, be paid back with interest.  Partner would be largely silent and does not want to participate in management. 

Is this too generous, or is this a reasonable offer since I will not have to come up with anything up front?
