You need to relax.

Now, when I'm not working I enjoy playing computerized chess and relaxing to classical music to calm down from all the information I have been bombarded with during my working hours. 

I think you'd be better off partnering with someone who has the experience and financial muscle to do this deal and learn from them while getting a piece of the pie.

I've had people to quit working for me 2 hours after they started due to getting sick and not being able to handle the work conditions of plumbing and sewer work.......It is not for a person with a weak stomach or weak muscles.

We make a good team, he's the muscle and money man and I run the numbers, schedule showings, and make the design decisions. 

I have purchased over 4,000 properties, been relaxing for a few years and seeing the world, but now have a new desire to grow again - and building my back office operations in Europe to manage US investments.  

NEVER relax your tenant screening, EVEN if it means additional months of vacancies.Do the best you can and screen tenants by rote, aka like every other tenant

I get so fatigued I can't do productive work- but I can't put it out of my head to relax!

I'd like to do the same thing as you (start analyzing a TON of deals), so that I can build that deal analysis "muscle memory", so that I'll actually be able to pick out a the great deals when I see them.

@Gail Kaitschuck, your post make so much sense and helped me to relax a bit :)
