@Ryan Brakefield unless the family member is giving you a gift then you can't use it for an FHA loan, same with investors. 

If you are thinking of deploying OPM (other than maybe your parents' gift money) to House Hack, then you might want to seriously consider your foray into Real Estate Investing. 

House gifted.

If it's too much of a sweet deal for you, the IRS may say his low sales price is in fact a gift of equity that could result in a substantial tax bill for your father.

Or did you mean you have another source of funds for the down payment, like a gift from family? 

@Brennan Davis you can also use gift money from family for a down payment. 

I have also used Gift and associates.

True it is cash, and Coinstar will give you gift certificates to lots of places.

There could be gift tax due if she transfers the $100K to you in one year.There are all kinds of different trusts and ways to set them up, so you need to again talk to the CPA and probably the attorney who set it up to find out how it is set up and when the assets of the trust might transfer to you.  

I don't want to trigger any amounts above the annual gift tax exclusion that would count towards my lifetime estate/gift tax allowance.
