If you're wanting to create a fund that brings in private investor capital to use to create and hold mortgages, meaning holding them as assets on your balance sheet, that's a different beast. 

Loan to _______________________________________ Balance $____________________________ Interest rate: _________ %, Monthly Payment $___________________ Loan Number _____________ Date last payment made____________________________ Loan current through _________________B.

This is a good checks-and-balances system to confirm info. 

@Seo Hui Han who pays & manages the onsite staff, is up to the owner.Some want to do it themselves, for check & balance, some want PMC to do, so they can be more hands off.

Balance of current loan with private lender is about $470k.pro forma (and actual cash flow) runs about $1200 net each month.Property is owned by an LLC of which we are the two members.Last week I got a quote from a company for a DSCR loan for 9.25%. 

We went forward buying houses in our own names until the point where our DTI got out of balance, and where the reserve requirement was higher than the next down payment. 

Considering the investment size and projected returns, how should I structure my financial involvement to balance the potential risks and rewards?

We've seen a very strong uptick in interest for small balance multi family properties and how to secure financing for them.

While I am not in a position to buy positions, I believe on your listing thread, it would be very helpful to share at least purchase price, current T12 NOI, and loan balance for both portfolios you are looking to sell. 

There's a balance between what's good for the seller and what works for the buyer.If the buyer can't afford the payments, they've been set up to fail.
