Savings for new purchase

[Anestis K.]

Hello, I'll try to keep this quick and simple.  In the past 10 years I have bought two, two family homes, two 10 acre lots, one condo and my personal residence.  I'm currently searching to purchase another condo but once again I have to deplete all my savings for the 25% down the bank needs plus closing costs. 

What other option do I have for down payment that the bank will not reject?  In addition, the investment properties are around the 100K price range.  Do I finance for 15 years and make $150-200 a month or 30 years and make 300?  

I like 15 years cause I want to retire early.  I'm 42 and my target retirement is 55.  I figured that if I do 15 year on the properties and buy one a year then every year I'm retired I'll be in a better place, as each year one property will be paid off and my retirement will get better and better the older I get. 

Your thoughts are greatly appreciated.
