The “Stephen Siu/ ACG Funding” Advantage – The Dream Team

Unlike other brokers, ACG is a DIRECT LENDER, just like the big bank without the “red tapes”. It can fund any loan size between $100,000 to $2,000,000 under the Fannie/ Freddie requirements.  For loans that don’t fit under the Fannie/ Freddie boxes, it can also fund or broker out as effectively as any conventional loans.  If there is a way and it makes sense, ACG will find the way to fund it.

On the other hand, no client is too small nor too big.  With over 20 years of experience and personal production of over $1,000,000,000 funded (i.e. 5,000 successful closed cases), Stephen still insists to review and oversee the loan process of every single file that comes to his desk.  Each day, he personally consults with his clients and takes in each loan application in person, to make sure each file closes smoothly.  When you work with Stephen Siu at ACG Funding, you are also working with the DREAM TEAM, and that’s the “Stephen Siu/ ACG Funding” Advantage.
