Financing question concerning a 40 unit apartment complex.

[Samuel W.]

My business partner and I are looking to purchase a 40 unit apartment complex. We collectively have 25% to put down on the loan. For context regarding our respective financial situations, my business partner and I both collect a $250,000+ salary each from our corporate jobs.

Will the bank require me to put my house as collateral? If so, how can I avoid this.
