Serious question fatherin law helping with first home

[Juan Campos]

Hello guys my name is Juan this is my 1st year working as a contractor an I have  taken an interest in real estate investing however with no previous work history and no previous filed taxes I know I won't qualify for a loan until at least 2 years from now however my wife and I have ran numbers and we can save up to 20k in the next 10 months

however my father-in-law has offered to buy my wife and I a home 

by putting the down payment and getting us into a home 

I know I can afford  a 200k mortgage without being housepoor however my my father-in-law has offered  to buy the house under his name  this would be his secondary home he has a home already almost paid off he has had this home for the last 30 years ( he suggeated a heloc i said no) 

my question here is how can we go about doing this?

 In essence he will be putting in the down payment for this home using a conventional 3% down loan we will move into this home and pay for the mortgage but he will be the one doing all the paperwork however I want to be present  With my wife throughout this process can this even be done is it even legal? thanks in advance
