Some split thereafterSmart syndicators do a match, or make-up return to keep things in balance provided there are enough dollars to go around.From there you'd need to figure out how to share the split the GP or managing entity takes among you and the person performing the developer role.  

It's a balancing act.Also, there are countless threads on BP on this subject, do a search. 

@Scott Skinger Let me explain, For Option 1, the prepayment penalty will be Yield Maintenance, Option 2 is a Soft Step Down prepay option meaning that in the first 2 years if you refinance or sell you would have to pay a prepayment penalty of 5% of the unpaid balance of the loan, then 4% in years 3 and 4, 3% in years 5 and 6 and so on.

Our goal is to never carry a balance on the HELOC for more than six months.

And for a third the reinvestment of net income is assured to really accelerate things for you.Get a multi year sheet going and figure your starting asset balance and the rates of each investment to arrive at a blended portfolio rate of return. 

Approximately 30 years (depending On loans) from now they will be paid to zero balances and I will have the equity to sell or refinance as I please.

Most mortgages don't allow them to be assumed by another party, and the "subject to" runs a risk of the mortgage company requiring the loan be paid off (i.e. for you, refinanced) (search "subject to" or "subject2" here on BP).Is the duplex worth more than the loan balance of $100K?

Your credit card provider may charge fees for a cash advance.Living expense: to pay for things like rent or utilities.Other: other payments that aren't a purchase of goods or services.If you use your bank account or PayPal balance, there is no fee to send money for a personal payment within the U.S.

So, both quality and quality of cash flow must be considered and balanced.

(I'll add that to the bottom of this post)Also, while not directly a foreclosure cost, other factors add to the unpaid principle balance.
