Escrow on the house with a mortgage (our residence) and no real choice but to pay ourselves on the house without a mortgage (MIL’s).
My “system” for the MIL’s house is to over-pay on my paycheck deductions for federal income tax, and use the return to pay some or all of the tax and insurance bill on MIL’s house. I realize this makes zero “logical” sense, but it’s a system I stumbled in and so I stick with it.
Yes, I’m certain I could be doing something with the money that I’m pathing into an escrow account that would be smarter, but there’s a value to me in the lack of hassle.
When I was younger I spent a fair amount of time chasing after tiny piles of sheckles but these days there’s just too much going on to find and eek out every dollar, and I have Learned that often I’m getting some convenience or piece of mind out of the lost opportunity.
