Many ways to buy a boat. First do a little research as to how the State Title/Register their boats. Internet search give you the person(s) to contact.
I hate traveling all over the country to look at boats I not take if they give it to me. So, I try to get a good idea from pictures and phone conversations what I will see in real before a road trip.
I have cash money right now burning a hole in my pocket for a boat. I have my; "I want" list I check from time to time to see if the boat(s) have sold and remove from the list if they do.
My "Buy a Boat" date is March/April when I be ready to run around and buy.
I have friends and family in a few key places from Texas Gulf around Florida and up the east coast to Virginia to take quick looks and pictures for me.
Usually when I go look at a boat. I sail away with it. I have done the research and most times know I will buy after a quick look. There have been a few times I not see what I thought I would see in real.
Personally, I would not pay any money when it be month(s) before I can really check out the boat. Too many boats out there, I not have to commit to just one. But, I like boats, so, many I like.

I will pay my money when I ready to take possession.
