I like the general train of thought here. My only hesitation is gifting to kids on an annual basis. When my wife and I were in our early years of marriage, my FIL started gifting his kids $5K a yr at Christmas. That went on for 3 yrs and then stopped. I would hear my wife and her siblings talking before Christmas time "What are you going to spend Dad's $$ on this year?". And then it stopped and you could feel a level of disappointment as the expectation of $$ was becoming built-in. Human nature, so I get it, but different than how I was raised as inheritance was never anything I ever expected.
I can definitely understand that, having that built-in expectation start to develop. There was one year, back in 2012, that my Mom distributed a bit of Grandmom's assets. She, my uncle, and I got $10,000 apiece. By this time, Mom was handling much of Grandmom's estate for her, but Grandmom was on board with this.
Anyway, I was under the impression that Mom was going to start doing this every year, to start getting Grandmom's estate down a bit. But, it ended up being a one-time thing. I also vaguely remember Mom attaching some strings, but after the fact. I don't know what the hell she thought we were going to do with the money, but she was annoyed that I used my $10K to pay down my mortgage some. I forget what, exactly, my uncle did, but it was something that annoyed her. I know he bought a brand-new 2013 Camry the following year, so that might have been it. But, in his defense his 2003 Corolla had well north of 200,000 miles on it, standing at death's door, and about to ring the bell. But, overall, Mom was annoyed, so there were no more distributions.
I think Mom was worried about Grandmom's estate generating too much in the way of taxes if it got too big, but in the end, we had nothing to worry about. Grandmom passed away in May of 2015. There was about $300K that got split 20% to me, and 40% each to my uncle and my Mom, and as I recall, not a penny of tax had to be paid on it.
Actually, I take that back. Grandmom had some money left in an IRA that got split among us. My 20% of it was $4800. However, I put it into an inherited IRA with Fidelity, so I'm only paying taxes on the RMDs. My Mom and uncle cashed their portions out, so they did pay tax on that.
