My question that I would like one to consider is this: Should I target a property that slightly cash flows with a 30 year fixed, or buy a home with a better rate 15 year fixed and target fast accumulating equity and a big fat cash flow egg that will be gifted to me in 15 years?

Why didn't you write the PSA using gift funds or, submit a letter of explanation for why?

I am in the final stages of a VA assumption, that was gifted to me by a family member with all its equity.

It could be a gift from family, or money that you have saved.I would suggest getting a part time job now, then transitioning to full time once you're done with school so you have work history to qualify for a loan.

The donor would just need to write a letter informing the bank that the "gift" does not have to be paid back.

Just make sure the lender will allow for x amount of gift funds depending on the loan program you are going with.
