so your buying a house, you have money and thats worth a kidnapping.
easier to do if you are in a place where you don't even know your way home
just a few things that should have been in the previous mention
You are young, possibly trusting, you are vulnerable if you even go there, take an armed and dangerous friend to photograph the guy and his auto liscense placks, perhaps dont even introduce the guy to your friend, you could meet in a resturant, with your friend at another table watching
JUST DONT GO THERE.
just extra thoughts. dont be trusting people until you have known them for a year or two
