What is a good deal for a private investor

[Mark Derby]

So, I've read a bunch of the search results but can't seem to find anything that answer's my question:

What is a good deal to offer a private investor. I'm looking for 30% of up to $700K, basically to fund down payments. From an investor's prospective, does it make sense to put up a down payment and own that percentage of the property, risk and all. You get 30% of what it produces after all expenses.

I'm assuming there would need to be some sort of exit strategy or buy out provisions written into the deal, such as no buy out for first 5 years but after that, it's at appraised value?

What are the common arrangement that you have used either as silent partner or general loan?

THIS IS NOT A SOLICITATION - NO OFFORS PLEASE!
