@Josh Jensen Not sure where the entrepreneurial spirit is in here... We're supposed to be mavericks and risk takers; deal makers and not dream takers. haha I say go for it if you find a good deal and you'll make it work.
As a suggestion put your retirement into a SDIRA (self directed IRA) either through your own business or in your wife's name. I can point you to some experts in this field (PM me). From the SDIRA you can trade the market (can do this is most IRAs anyway), more importantly you can use it for REI. One caveat is that it needs to be seasoned 5 years to use. I'd look at doing this anyway if your intention is to continue in REI.
Another option is take an early distribution; you won't get hit with the penalty because of the CARES act and use those funds as your emergency and then invest the rest in active REI so you can grow it. your 40k will grow much faster in active REI than passive stocks, which are about to get hit again (not a popular belief, maybe).
Push off your student loan debt as far as possible or structure your payments so they don't effect your cashflow. Should be able to do this with lender too because you've been affected by COVID.
Create a strict framework for your deal and only buy if it fits that framework. Be disciplined and patient. Meanwhile build up some sort of RE business, or RE license and continue to be a student. Between Utah and the family you can also build in economies of scale and save money buying in bulk. You'll be good, and I see more options than obstacles here.
I also have 3 children (another on the way) and have been rocked by the pandemic economically. I keep something in my mind from childhood - "When the going gets tough, the tough get going". Maybe you can use that in your life as well. Go for it and if I can do it, you can too.
Also I'd like to protest Microsoft's ruling on making double spaces after a period in MS Word an error. Weak sauce.
