the other issue is that i feel i have no more time left in life I mean I am 36 so I should do things quickly and I cant get myself do anything else then think about horses ---I cant afford a pedegree but I can get spend 2-3 thousand dollars and approx livery is 200 dollars with the hay etc
You still have loads of time, I bought my first horse at 44 years old..don't do things too quickly!
The price of the horse is nothing compared to the cost of keeping one.
You would be better investing in additional lessons for now as it will be cheaper than buying a horse !
Ride a lot of different horses, try some more difficult ones. Learn stable management as you will need it when you will buy a horse.
If you are lucky your horse will not have any health problem but I see a lot of people not being to ride their horses from weeks to months because of lameness or other problems that can develop so it doesn't mean you will be able to ride all the time. I could not ride my horse for a 1-2 months because the first saddle I purchased did not fit correctly so it was hurting my horse's back. I had to get a chiro and a physio to rectify the problem and now I only use a qualified saddle fitter.
Other costs : farrier (every 6 weeks), livery, feed (if not included in livery), insurance, petrol, weekly lessons, saddle check (mine is every 6 monts), teeth (mine is every 6 months), physio (if back problems), vets fees (if not covered by insurance), vetting (when you purchase your horse).
Stuff you will need to buy: rugs, saddle, bridle, headcollar, lunging kit, first aid kit, grooming kit, buckets, saddle cloths, numnahs, stable tools, etc...
