There are lots of finished and unfinished kits available.

You can buy one someone else built.

The point is to get the benefits, such as qualify for the repairman
certificate, you have to have done the majority of the work yourself.

WRONG (again). There can be multiple people involved, as I stated,
such as the person whom you bought it from.

"What if you bought the project from a previous owner who never
finished it?
It does not matter how many previous owners a project may have had -
as long as each owner intended to build the aircraft for their own
education or recreation - if you can document or show documentation of
the work that each did, it is as if YOU did the work!"

Correct as far as registration goes, but to get the repairman certificate,
you have to show you were the primary builder and you know enough to keep
the thing airworthy.

That gets you the repairman certificate, which authorizes you to do the
annual condition inspections yourself.

None of this has anything to do with LSA's.

Irrelevant. Many of the models I'm looking at are
all of the following...LSA and ELSA and yes even SLSA all
in the same final product. The distinction is the process
by which it came to completion.

None of this changes the fact that if you, as you said you planned to do,
swap props for more performance on an aircraft flown under LSA rules:

Wrong. LSA rules don't apply in Costa Rica.

If the aircraft is a LSA, you invalidate the airworthiness certificate, and
the airplane is now little more than scrap.

Wrong. The manufacturers have props which allow the
plane to go 170 or 180 mph. The airworthiness certificate
remains intact. Now you no longer have a light sport plane.
It can be sold anywhere to private pilots, or flown outside
of the United States.

If the aircraft is certified, it can never again be flown as a LSA.

Well sure. Same is true if you do what a lot of people
do, which is...put in a backseat. Or take off the winglets.
Or add unauthorized wheelpants. Etc, etc. Only a fool
would throw off the CG though.
