Easter Island has Hawaiian level surf with volcanic reef set ups. Expensive to get to , central,Americas but Air BnB I don't know ! Most surf destinations know their worth and home stays can be interesting but challenging .
Really rewarding if you get a good one!
Fiji , Maldives , Resorts only. Mentawais some home stays. At feral level, epic to get there and no real wide ranging access. At feral level there is no lifesaving care anywhere, third world travel means you are on your own survival skills . So seriously needs travel insurance of the best kind, ( most resorts require you to have full medivac insurance) any less you could bankrupt someone near and dear.
What are your first aid skill, will you take medication against tropical diseases.
BTW $1700 might cover airfares. You are seriously out of your league in cash anywhere outside of central America.
As for boards , they can quite specific for where you choose to go. Good paddlers, transportable ( airline issues).
Cruise beyond this forum Google surf..... Wherever get a set of places with cost then search out reviews for the same.
Keep talking on the forum , look at the surf map on Surfing Waves there is information there too

WOW

I went on Airbnb for surf stays, it looks quite feasible , I'd still consider Central America use the saving in travel costs for a longer stay! Please report back so others can follow in your footsteps!
