Listen or read carefully.
The world is full of unhappy or unsuccessful Vets, whinners when they were in and most still are, so consider the source of opinions and if that is really sound advice.
If you can't stand it get out. If you can stand it, consider staying in, it gets easier as you mature and advance in rank.
You'll work twice, maybe three times harder than you are now getting out and trying to get started in RE, there is nothing easy about RE or any other self employed venture.
Education is not a gurantee to success, but it does open doors that are locked to those who have less of it. If you have an education specialty or skill in high demand, that is a factor to consider, but you are unlikely to get rich working for others.
Be careful in getting sucked into the dream, the right attitude and confidence are good things, neither put bread on the table. Thinking the grass is always greener on the other side is not always true.
41 is actually a great age to really begin a full time RE business, your maturity will be a great asset. You can invest and learn RE while serving in the military, we have some active duty investors here. Ask your wife if she can or would want to get involved in RE, she can probably take care of anything with you being gone.
90% of those that begin in RE as a full time job fail within 3 years, all had the dream, had the right attitude, had sufficient intelligence and had confidence when they started.
I invested while on active duty, had rentals and flipped a few deals, did installment sales. I could always turn issues over to family if I was gone.
Also consider the reserves, you might consider an inter-service transfer if you want to get away from ships, you may be able to go to any service. Consider the Coast Guard as they rarely go far for too long, you could spend years without going anywhere.
My dad retired from the Army National Guard, the money is money, but looking up pay schedules isn't the big picture. Wait til the kid breaks a leg, your wife needs surgery or you need some ongoing treatment.....the medical benefits can far outweigh the money.
Okay, you are 42, kids are gone and wife says she wants to go to London for a week. No problem, just check the MAC flights and take a hop. Want to buy a new projector beam communicator? Get a discount at the base exchange, they deliver too. Need an attorney, just call JAG!
The retirement pay isn't the only benefit, add the money you can save as well.
I don't want to sound like a recruiter, but the military is one of the best jobs going with only a 20 year hitch to full benefits and pay.
You do have responsibilities to the family too, what are they saying?
Now, some reality on the down side, you may not be able to stay in, to ensure you can you'll need to make some career decissions along the way, staying with jobs and specialties that are in demand. They retire officers early too, ask me how I know!
I was very lucky, the one out of a hundred, maybe a thousand as I got out and joined the reserves and guard but what took me out was relocating and having to find a new unit. I'm paying for about 6 to 7K for some dental work I'm in the process of having done, I can pay it but it would be nice if it were free.
It's your future, think hard and long! :)
