The equity is actually what you are paying for the property.In this case let's look at the numbers that count,...the current numbers.You have about $500k or more in equity, which is buying you a property that's worth about $700k (I went with the lower PV. 

I realize people are trying to make a living, but anyone who cold calls me is the last person I'd use for any transaction (plus I have people for that!).  

I have a potential private lender, but I need to determine if this is a viable investment opportunity and explore the best financing options You posted this same thing three times - in two it was a 36 unit and in the third a 32 unit.Do you have any other details about the transaction or perhaps wish to share your initial analysis so the volunteers here can poke holes in it or tell you why you're right?

The QI has to be an unrelated 3rd party to the transaction. 

. $275K acquisition  and you believe a 40 year amortized loan is necessary to make the numbers work, this transaction may have bigger problems.  

So happy for my investors hopefully the rest of the transaction goes smooth so we can get it all locked in and they will have one more property in their portfolio than they did a few months ago.

I am not in the flipping market but I handle multifamily transactions for buyers and sellers who are very transactional.

Your brokerage is required to supervise you, and maintain all records of the transaction, just like any other client. 

They can bring it to open market and facilitate the transaction.
