How should my brother and I structure our real estate purchase?
We’re buying the home right over $200,000 so that means he will only need to put down (as a ‘gift’) roughly $7000. I'm with the others, don't call this a gift unless it is a gift.   I'd have him check with the bank that previously refused him a mortgage if putting both of you on a mortgage would allay their concerns.  Your cash flow would be paying the mortgage payment and if you failed to do so, then they could fall back on his.  That may make more sense to them, even if they would deny each of you a loan on your own.  This works for them because either of you is responsible for the whole loan.  It works for him because he was already willing to be responsible for the whole loan.  And your alternative plan makes you responsible for the whole loan, so this is just as good for you.   At what percentage would you suggest splitting ownership and future expenses? Typically a cash/financing partnership would be 50/50, but since it’s only a 3.5% down-payment instead of 20% is that still fair? Surprisingly enough, a 3.5% down-payment that accumulates is about half the equity of a 20% down-payment.  So your suggestion of a 25%-75% split makes sense if 20% would give a 50%-50% split.   I expected it to be considerably lower.  The way that I calculated it was to have his share increase by his equity share of the "rent" which I set to the principal plus interest payment for a thirty year loan.  With a 20% down-payment, this would give him 84% equity.  With 3.5%, about 40% equity.  I'm not sure why 84% equity should be the equivalent of a 50% share, but it may be a side effect of other expenses.  Perhaps taking property taxes out would reduce the equity share.   Note that if you increase the down-payment to 20%, your mortgage payment will drop substantially.  The difference in interest between 3.5% and 20% equity is a couple hundred dollars.  Also, you'll be able to eliminate any PMI payment at 20%.   It could be argued that if he pays a third of the monthly mortgage payment, that that would give him the same 50% equity stake on a 3.5% down-payment as he would get with a 20% down-payment.  The problem there is that then he is effectively subsidizing your monthly payment.  If he were to stop doing that for some reason, you'd have what is effectively a 50% increase in your rent.  It would be safer for you to handle the monthly payment while he handles the down-payment.   If you couldn't pay the mortgage, it sounds like he is in a position to buy out your equity, rent the property, and take over the mortgage payment.  If he stopped being able to pay his third of the mortgage, it's not evident that you'd be able to pick up the slack from him much less buy him out.  And it's unlikely that you'd find someone else willing to replace him under those terms.  But your brother could construct things such that in the face of tragedy, you'd inherit his equity in the house.  If you're making the entire mortgage payment, that's a stable situation.   He's not at risk because he could take over the mortgage if necessary.  You're not at risk because you inherit his equity share and can afford the monthly payment.  So even in the face of tragedy, things can go on.  And that's important, as otherwise you could lose your equity in the house.
