How to put $100,000 to work

hey folks I am new to the forum I’ve been digging around on both this website as well as loopnet for quite sometime gathering information and doing research on investing in mobile home parks, I have recently come into an inheritance of $100,000 and want to put this money to work in the form of investing in mobile home parks. How far can I expect this money to go? I have seen quite a few attractive parks in the 300,000-400,000 what kind of downpayment would be required to finance a purchase in that price range for someone with great credit (700+ credit score). Would I be able to get away with a 15-20 percent downpayment? Any input or guidance would be greatly appreciated.
