Ocean View is at the southern tip of the Big Island of Hawaii, where I happen to be licensed as well as California. There is a new grocery market that just opened, video stores, pizzaria, burger joint, bar and grill, Ace Hardware, a vet clinic, chiropractor, medical clinic, quick stop stores, laundramat, several gas stations and a new plaza being built as I type this! The homes are all on "catchment" system for water, meaning you have a large "pool" type of container and rain gutters that catch your water, and that can be a challenge during drought periods. That being said, most people on catch love it, its free and there are water companies who deliver when you are low and no rain is in the forecast. Lots above the highway in Ocean View are almost always one acre and lots on the ocean side of the highway run 3 acres and more
Ocean View is very local and about an hours drive to either Kona or Hilo and the airports in both. The housing is the most affordable on the island for sure, and there are some really lovely homes there. There are several different subdivisions in Ocean View, some below the highway and one very large one above. Beaches are a short drive and so is Golfing, 2 courses within minutes. Volcano National Park is about a 25 minute drive.
You may want to consider Na'alehu and Waiohinu just a few miles south as well. Discovery Harbour is a wonderful subdivision (I am a homeowner there) built around a Robert Trent Jones Jr. Golf Course with all city amenities built in: water, fire department, electricity, Roadrunner cable tv and high speed internet, paved roads, terrific views, a very active homeowners association. Mark Twain Estates is right across the street from Discovery Harbour, but lacks many of the city amenities. Most homes there do have water and power available though. Those who value their privacy and being a bit more isolated prefer Mark Twain. Lots in these 2 subdivisions run from 1/4 acre to almost 1/2 an acre.
Of course, Hawaii is a special market unlike any other in the United States and I can't stress enough the importance of working with a good REALTOR who knows the area. There are always concerns here that mainlanders don't have: ie: lava zones, tsunami zones, vog, water catchment areas, rainfall amounts, etc.
I would love to be of any assistance if you have any other questions or concerns regarding the Big Island....I know it well!
