Wanting to go offshore in 2 yrs - buy right boat now ?
All things being equal, buying one boat now, knowing you are going to buy your ''real'' boat sometime later is never a good idea financially. Its expensive and often it is difficult to sell a boat.
Now is a good time to be a buyer. I might suggest the following:
1. Join a sailing club or some association like JWorld where you can sail THEIR boats. This is generally much cheaper than chartering and often you get access to different types of boats. You will get your sea legs back and learn more about boats.
2. Then spend at least 1 yr looking for your ultimate boat. I guarantee your thoughts will change in that time and you will end up with a different and better boat that you first thought you wanted.
You will save a lot of $$$ with the above approach.
Best of luck
