Welcome to the Seabreeze Cyber Yacht Club snapperfish. It is a pretty fair crew here and very good advice is forthcoming if you need it. Just ask.
However please take the time to search the older threads as some of your questions may have already been discussed and answered.
A 34 foot mono hull yacht is a great choice. Provisos are that it is less than 6 tonne displacement fully laden for an extensive cruise, sloop rigged, is not built of concrete and is not a "Roberts Design".
Ooops!! Where is that fire blanket and extinguisher!!

Oh yeah. As Sands says; check your local market first. Deliveries have a tendency to blow out even the most generous budgets.
Also as Ramona said; check out that Van De Stadt 34 on Ebay. They perform well and are very roomy yachts for live aboard. Cheers Cisco.
