Posting for my Mom:
This is the least expensive types of burials of all on the premises. Cremation Wall Niche located indoors at Eternal Hills Memorial Park in Oceanside CA in the Alcove of Hope. Includes two rectangle Sand colored Marble Urns. You can put things in the Niche such as pictures and momentos. You can also decorate from the outside. This cost covers the actual property of the Niche and the Urns. There is a $400 transfer fee to change ownership & deed through Eternal Hills which can then be applied towards the pre-paid arrangements for the opening and closing of the niche and any other expenses when needed. You would make all those arrangements with them. You can lock in fees with them now even if you don't use it for years. Again this is one of the most affordable burial methods.
