We're in Central CA, Coastal. Five years ago put $85K down on a modest 2 bedroom condo and took a 5/1 ARM (at 5.5%) for $340K. That loan reset in October and they jacked the interest up to 7.5%, so we're refinancing and just locked in a 30-year fixed at 5.65%.
We had help with our down payment, from my very creative FIL. He has four kids, all of whom he would like to help with down payments, but only $70,000, which he also needed income from to supplement his retirement. Split 4 ways in CA, that money wouldn't go very far, and put into a savings account he wouldn't get much interest out of it. So he gave it to us first, and we pay him 5% straight interest on the loan, monthly. The deal is that when the next kid is ready to buy a house, we refinance or otherwise pay the loan forward, send the $70K to the next kid, who then takes over the straight 5% interest payment to him, and so on.
The other $15K we saved in one year by LBYM; If we'd had to do the whole down payment by ourselves we would have moved into a studio, ditched a bunch of our stuff, and worked our tails off for a couple of years. FIL made it come easier and quicker, and we're grateful for it. But we spent the last five years LBYM, saving like mad, and building equity in our condo so that we could pay the next kid off when the time came. So, in a sense, we saved our down payment in a few years by LBYM, but AFTER moving into our current home.
I love the ingenuity of this plan, and it's working well so far.
If you get some sort of deal like this with family, be aware that many lenders don't like or won't allow you to have a loan for a down payment (unless you're working out a 80/20 scheme with them or so forth). So you might need to figure out a way to work around those requirements.
