Net operating income last year was $2,108,139.  Current price tag is a 7.9% cap rate, but think you can buy closer to 9% cap.  At a 9% cap rate cash on cash return on a 30 year fixed loan at 5% interest would be over 20%.  I've got the financials and on top of helping you purchase am a certified apartment manager with over 12 years of experience in multi-family housing.  I think numbers could be better as some administrative costs could be saved as well.  

If you have $4 million to put down now is the time to put your money to work.  Definitely some value add opportunities with this property as well.  PM for details.
