Financial set back

I'm a bit bummed.

My plan was to learn as much as I could for a year or so, save up a nice chunk of money and buy a 2nd rental property.

Yesterday, I was informed of an expense that will take a nice chunk out of our emergency fund. It is a personal-family expense that I knew was coming but I didn't know when the due date was and thought we could cash flow it. It reminds me of a bill we got from an architect. All the previous bills we just took from our checking, a thousand this month, 2 thousand the next and then one month we got a $8K bill that had us scrambling, selling off stock and draining accounts. This new thing will have us doing the same thing, draining accounts, but not selling off stock. Yes, we could pay late. I have a high credit score (high 700s, once used to be 810) and you don't get that from paying stuff late.

This will set me back about 2-4 months from my plan.
