You will need to sit down with a lender and discuss how much you will need for a down payment. It depends on what type of loan and interest rate depends on how high your credit rating is. I hope this helps you! Good luck!
The required down payment for multi unit investment property loans is 25%. As for interest rates, that would be dependent upon several key factors, including your credit score and how many units you are purchasing but in general your rate will be about .5% - .75% higher than the going rate.
If you would like to further discuss your situation I would be glad to help. Please email me and we can coordinate a time to connect on this.
