I feel ya, I have one property paid off and one with a low remaining balance.
What I did: Sold a 3rd rental at peak 2021 and stacked sats hard.
1.Divide your mortgage by 12 and make and extra payment in that amount each month. You'll cut your 30 year to a 15. If you have a low interest rate your in the green if you can keep your job.
2.Keep stacking sats.
3.Eliminate debt, credit card, car loans.
4.I keep a small amount of gold in my get out of town backpack. Zombies, hookers, and road gangs might not take sats.
5.Bury all the Jack Daniels and Marlboro cases you can on your fall back property.
No one knows when the bottom will fall out, but its not looking sunny. All we can do is position ourselves to be ready.
