I have a number of scenarios, doing deals with family members, and doing deals with non family members. The essence is pairing up those with income to show but cash poor, and those cash rich but no income. I'll explain.
I was fortunate my mother in law was fascinated with real estate. She and her husband were super savers, and with the death of her husband collecting his life insurance, 30 years ago, had over half a million cash, a good sum back then. She had a small pension, but basically in the same boat as those with lots of cash, but not much income to show.
At the time, my wife was a finance company VP, me a programmer, a field that pays well, and my brother in law, a doctor. What she proposed that we all partner up, she with her cash, and us with our good incomes, excellent W2's, and together we make offers on properties. She proposed the same deal with my brother in law. We, the kids, each contributed cash as well. So, with her, we picked up several properties in NYC in the early 80's. Similarly, she did the same deal with my brother in law in San Francisco. Both areas experienced dynamic appreciation since, and working together, we all manage to acquire properties before the market bottomed out in the mid 1980's, then rode it to the next peak.
One other benefit working together as a unit is my wife has her name on some of mom's bank account. So in some cases, with deals that we do ourselves, at auctions for instance, they ask you, do you have the cash to complete the transaction, we show them the joint account with mom, and we're good to go. Also, some want to see if we had the cash for a number of years, aged, which mom's account do show, going back 10 years, and not some recent deposit.
Then, I found a creative realtor looking for a partner to do deals. So if they seller wants to know if the deal can be completed, I'm there to say I'm the income partner with W2's, tax returns to show. If they want to see where the cash is coming from, I got mom's statements to show. The partner and I just split the profits from the deal.
Doing deals this way does sometimes present hilarious consequences. In the mid 90's I was refinancing a few of my rentals, 2 of which I partnered with my MIL. The bank wanted paperwork for my MIL, got it, and found she partnered with my brother in law in San Francisco doing deals. So they want his tax returns. Turns out he partnered up with some other doctors doing deals as well. While I was discussing how long it's taking with our loan officer, even she thought it was getting ridiculous, because by the time they're done, if they ever, they'll wind up checking out 50 different people, maybe 40 doctors.
Fortunately, I have a Wealth account at my bank, and they wondered why we didn't go to them first. They already have info on us, so they said just get us updated tax returns, and W2's, you're go to go with us. We'll leave your MIL, BIL, his partner doctors out of it. We'll just consider you, and you alone.
So you'll have to find a way to market yourself, you're the cash guy willing and able to do deals.
