In order to own a commercial multi-family property, any property with at least 5 units will need to be owned by a company (ex. LLC), not an individual. The magic numbers are 1-4 units is residential, but as soon as you hit 5 units, the game changes.
First off, I would ask the owner why the price is as high as it is. What are comparable units in the area priced at? What is the owner's motivation for selling? Does he need the cash from the sale ASAP or is he a buy and hold owner who is looking to get as much profit as he can out of the property?
If you are absolutely set on getting this property, here's how you can get it. Negotiate the price lower. Tell the owner you'll pay 70-80% because a bank won't possibly accept the price he is asking. If he refuses, you still have at least two more options to consider. One would be owner-financing. You wouldn't even need to negotiate the price any lower if the monthly numbers work. Why? Because you won't need to put any money down, the property will cash flow, and the owner will be receiving his monthly check (acting as if he were the bank) for the length of the term you two agree on (15-25 years). As a last resort, you could seek a combination of hard money and/or private lenders in your network/area. "But I don't have a network." Yes you do. You have doctors, a dentist, real estate agents, lawyers and other people who you know. Go present the deal to them. Act as if you were meeting with a bank. Be as professional as possible- this is purely a business transaction/investment.
Now that I've told you how, you have no more excuses. Go get that property. :)
