Trust me I have been there before and it's incredibly stressful having to deal with all that. 

Also, the math on the state exam is WAYYYYY easier than the math in the study books so don’t stress over that part too much.

If there's a hole, it may be a red flag.b) sensitivity analysis: I examine all the assumptions, and make sure I can live with the worst case scenarios.c) "Stall and see": if they are getting money over multiple years, and there is no penalty for investing later, I would usually wait so I get some real performance data, versus having to look at theoretical pro forma information.d) Recession stress test: I will not invest in anything, until I subject it to recession level stress and see if I can live with the result.

Factor in all possible expenses (and have a reserve) and stress test the numbers for what your break-even point is at what occupancy.

Not rewarding yourself from time to time can be stressful.

You are going to get stressed out and discouraged.

If you don't like it when the lease is up make them get out, but imo as long as your getting your money, and even more, I wouldn't stress it to much.

I cannot stress enough the importance of having a large cash buyers list before you really put yourself out there to land deals.

Stress test it, run it more conservatively, and hopefully still be confident in your return.Assuming you followed your investment rules, then go back over your investment criteria, and re-confirm to yourself that the deal meets your criteria.I find that the more I go back over my homework, know that I’ve rigorously followed my investment criteria, and keep seeing the same positive results, the more confident I become in my decision.

Stress test all of your deals thoroughly and ensure you have the correct systems in place.
