Help with 6 unit building

[Kyle Penland]

I've found a 6 unit apt building for sell, asking is 159k, gross rent is 2610...Water and trash run 100 bucks a month combined on average...Some more some less.  The agent that brought me the deal is confident I can get it for 150k...maybe less.  My lender wants 25% down.  I don't have 25%, seller isn't willing to finance.  My questions...Can i get this with LESS than 25% down... For example, 10% down or 15% down?  Also how long can the mortgage go...My go to lender says max he can do is 15 years...Anyone have any ideas?  There is some room to improve rents also, so there is some meat left on the bone.
