Multimillion multi family costs

[Arleigh Campeau]

I’m looking at the feasibility of a 50 unit multi family complex. This is my first look into multi family of this size. I’m wondering if anyone can ballpark the closing costs on a 4-5 m$ loan. Also, I have partners that can potentially fund up to 400k for the down payment. Is that enough to get into a property like this? Any help is appreciated. Thanks!
