How should my brother and I structure our real estate purchase?
While I agree with the existing bulk of comments and answers that you can't tell the lender the $7k is a gift, I do think you might have luck finding a mortgage broker who can help you get a loan as a group.  (You might consider as an LLC or other form of corporation if no one will take you otherwise.)  That is, each of you will be an owner of the house and appear on the mortgage.  IIRC, as long as the downpayment only comes from the collective group, and the income-to-debt ratio of the group as a whole is acceptable, and the strongest credit rating of the group is good, you should be able to find a loan.  (You may need a formal ownership agreement to get this accepted by the lender.)  That said, I don't know if your income will trump your brother's situation (presumably high debt ratio or lower than 100% multiplier on his income dues to its source), but it will certainly help. As to how to structure the deal for fairness, I think whatever the two of you agree to and put down in writing is fine.  If you each think you're helping the other, than a 50/50 split on profits at the sale of the property seems reasonable to me.   I'd recommend that you actually include in your write up a defined maximum period for ownership (e.g. 5yr, or 10yr, etc,) and explain how things will be resolved if one side doesn't want to sell at that point but the other side does. Just remember that whatever percentages you agree to as ownership won't effect the lender's view of payment requirements.  The lender will consider each member of the group fully and independently responsible for the loan.  That is, if something happens to your brother, or he just flakes out on you, you will be on the hook for 100% of the loan.  And vice-versa.  Your write up ought to document what happens if one of you flakes out on paying agreed upon amounts, but still expects there ownership share at the time of sale. That said, if you're trying to be mathematically fair about apportioning ownership, you could do something like the below to try and factor in the various issues into the money flow: The above has the benefit that you can start with a different ownership split (34/66, 25/75, etc.) if one of you wants to own more of the property.
