A few random thoughts this morning. Checked our retirement accounts and hit another 100k threshold.

Looks like we crossed the previous one for the first time in April 2019 and then again in May 2020. Either way, pretty good. I know the stock market is crazy good but it still unbelievable sometimes just how much it can grow when the balance starts to get larger.
For a variety of reasons, promotion for DH, which had enabled us to save my paychecks since summer, a small inheritance, cash back from credit card rewards, travel completely subsidized by credit card rewards, and continued decreased spending due to reduced activities, I find that we have $40k over our emergency fund in checking/savings accounts. My husband and I talked about things we could do with that money as it doesn't need to be sitting in a savings account making next to nothing. We do have 2 older vehicles that I plan to drive until I can't anymore, but as they are a 2002 and 2005, a new vehicle is in our future, although I hope they can both last another 5 years. So some money does need to be available for that. Options that we discussed are paying down on our house. Current balance is $71k at 3.25%. So even if we did the entire $40k it wouldn't be enough to knock it out. We currently have 9 years left so it will be paid off at least a year before DH will retire. Except for this money all of our money is in retirement accounts, so we could use some to start an investment account and potentially use that for a new vehicle down the road. Or option 3, spend some of it doing things around the house that need updating.
For now we have decided on a combination and that we will start with spending some money on the house. We are currently in the process of a bathroom remodel and new floors, but since all the materials were purchased with my credit card rewards, we still won't be spending that much. But we could use new furniture, lighting fixtures, and a mattress. So maybe with labor we'll spend $10-$15k. For those of you on the credit card thread, this will help with my $30k MSR for the 2 Biz Plats I just got.

So then when that is all done and paid for maybe start an investment account? I know there are different schools of thought on whether or not to pay down on a house, especially with a low interest rate, and I would really love to have it paid off early, but then I see the gains our retirement accounts are making and would love to get some nonretirement money into that.
Lastly, DH and I decided to go with a high deductible health plan and HSA for next year, as his company upped the matching yearly contribution to $3000, making it pretty much risk free. We also maxed our flex to spend on braces that for sure one of my sons will need next year. So by my calculations his paycheck will go down about $100. We'll see how close I am. With the extra money that we have I'm wondering what you all think of just paying our medical bills as they come oop and not even touching the HSA if we don't have to? This also gives me the benefit of being able to put the expenses on a credit card

Any and all thoughts are appreciated.
