So on a 100k property I'm looking at about 15k down plus closing and seller contributions up to 2% towards closing.

So my question is this: I have a profit sharing account from a prior employer (which no contributions are made, just interest) and a separate one with my current employer.

For example, if you split the rehab into 3 different phases then in theory each of you would have to contribute 5k per phase. 

What you're trying to do is called a contribution of capital.  

. , who didn't really contribute to the conversation this time, but another conversation we had saved me about $3000.

These are typically 1-1.5% less than an equivalent term fixed-rate financing - either you pay the lender to hedge interest rates (fixed-rate product) or you hedge them yourself (use a variable rate, but set your payments as though you were using a fixed-rate products).If you search the forums, there are longer, more compete treatise on Canadian mortgages and strategies to which I and others have contributed in the past - I'm just never able to find them when I need to reference them (@Mindy Jensen - where's my virtual cork-board ;-) )

What will you do if Capital contributions are required but... one owner does not have any Capital. 

It would be wiser to contribute your money to a income fund with a higher return than your present  mortgage interest rate. 

I had the chance to read through some of your contribution son other posts.

The amount of money that each investor can contribute is also limited on the net worth of the individual.Bear in mind that this process takes considerable time and money to develop the legally required structure that will allow you to proceed with a syndication.It is very possible for you to do, but be prepared to take the long road to get there.
