Hmm, insufficient replies here... first of all, know that the liveaboard lifestyle can be challenging regardless of nautical experience. Out in Kalifornia, heaps of folks live aboard boats at marinas, and many of them are relatively clueless when it comes to operating sail or power craft. Their boats are merely "condos on the water" and many of them hardly ever leave their slips. These folks pay moorage (or slip fees) every month, or every so many months, with marinas often requiring deposits, proof of insurance for the boat, good credit history, etc. In return, there are amenities: showers & heads on shore, dockside water & power, sometimes a clubhouse, hot tubs & pools, BBQ areas, etc., but expect to pay a little more for each additional amenity, particularly the luxuries.
You can find "transferable slips" in certain marinas, which means that if you purchase the boat, it stays in the slip and you simply assume all the responsibilities (i.e. bills) which the former owner had. Another possibility is to buy a boat on a transferable mooring buoy, much cheaper but also much harder to find, and with zero amenities as opposed to living at a marina. Last I heard, the San Diego Unified Port District waiting list for an open mooring buoy was 2 or 3 YEARS, and that was awhile back, LOL. So the whole mooring buoy scene can be elusive, like Sasquatch or his cousin the Yeti. Folks don't wanna give up those mooring buoys, sometimes they'll hang onto them even after they sell a boat, and put another boat on the buoy once they get around to buying the craft.
Then there's the truly hardcore option of living aboard a boat without the amenities of a marina or the security of a mooring buoy... 'security' in terms of your anchor not dragging and your boat winding up on the rocks, or on a lee shore with no hope of salvage or recovery. Not in your budget, most likely, unless you both have enough money set aside for such contingencies. This sort of liveaboard lifestyle should only be attempted by those with some nautical experience, and the challenges (or difficulties) of such a lifestyle can be great. Starting with the greatest priorities: resupply of fresh water & provisions, handling of sewage, dealing with dirty laundry, repowering of shipboard batteries via solar panel(s), reliable dinghy transport from ship to shore, and the list goes on...
Imagine doing any or all of this while caught in a sudden squall or rainstorm... good foul weather gear starts to enter the picture, LOL. I won't even get started on all the bureaucratic hassles & paperwork involved with sailing from one country to another, even sailing into Mexican waters has become problematic with the diplomatic tensions ratcheted up between nations. And I'm NOT trying to dissuade you from the whole adventurous idea, it's just that we now live in a world where one can unknowingly get into... er... a boatload of trouble due to ignorance of regulations or requirements where foreign travel is concerned. And to be perfectly honest with you, I've been considering such a voyage, if only for a year or so... but I digress, lemme give you some more advice.
To live comfortably aboard a boat, two people will need at LEAST a 30' craft, which is convenient because finger piers at marinas are often 30' in length. There are longer finger piers for longer boats, and end ties and whatnot, but 30' is the minimum for liveaboard action if you wanna be comfortable, take my word for it. A better choice would be between 30' & 40' feet, a Cal 34 for instance... and some marinas will allow a slightly longer boat in a 30' slip, as long as no part of the boat obstructs the main dock, aye? You with me so far? Trust me, you WANT the additional liveaboard space down below when there are two persons in the equation... when it comes to stowing personal stuff like gear & clothing, it'll be hard enough working out a system which works for both of you...
If you're into comfort as opposed to boat performance, go with a beamy (or wide) cruising model, and be sure to go below and check the accommodations, living space, etc., BEFORE you buy a boat. Can't stress this enough: you're the ones who will be living aboard the craft, so make sure you will be comfortable aboard that same craft. Look for a good galley layout too, since that makes a huge difference in the liveaboard lifestyle... you want some counter space, a good stainless steel sink, a gimballed stove or oven that actually works, room for a microwave & small fridge or thermoelectric cooler, etc. I know all this because good friends of mine have lived aboard a boat for years, and I often visited them in Dago (or San Diego) when I lived there, as I may do again.
And yes, they owned a Cal 34, which is a pretty good choice for living aboard a cruising sailboat. There are others which fill the bill, I'll be sure to include a link or two in a moment so you can see what I would choose for my own purposes. Know this: as soon as you get above 30' LOA (or Length Overall), cabin room down below magically and (almost) exponentially increases to a point where comfort is king, and THAT is what you want if you're going to live aboard a boat. Putting up with all the other bull$h!t (i.e. making sacrifices) in order to live your dream, well, that becomes much easier when you're living aboard a 34' boat rather than a 30' craft. You still with me here? If you're gonna do this, DO IT RIGHT... but keep a limit on overall length because it gets expensive, LOL.
Okay, I'm gonna stop here due to time constraints, but I want you to know that living aboard a boat can be challenging, yet it can also be rewarding in ways that few landlubbers will ever understand. You'll be closer to nature for starters, even if you're dockside... you'll see all kinds of cool sunrises & sunsets, see wildlife to include sea birds & marine mammals (birds can pose a problem if they routinely cr@p on your boat), breathe fresh air most of the time & enjoy that powerful connection to the ocean which we all have in one way or another, whether it's through ancient marine ancestry or some other more modern line, LOL. And I know, I hail from a nautical family (2 CDRs, USN Submarine Service, I was in the USA INF, go figure), and it ain't my first day out when it comes to sailing.
MY BEST MEMORIES INCLUDE SAILING VOYAGES... LIFE ABOARD A BOAT IS COOL, AND THERE ARE WORSE PLACES TO SPEND YOUR TIME. JAIL WOULD BE MY FIRST COMPARISON, LOL, ESPECIALLY AFTER BEING FALSELY CHARGED. MEH, LIFE GOES ON... CHEERS!!!
Here are a couple of links or boats I found on short order, they're both 37' but the Ranger is probably better known for performance... the Talisman looks heller comfortable down below, which is still important. If you're on a serious budget, lemme know, and I'll pick out some other craft, but the lower ya go in price, the more likely the boat comes with problems which you will surely inherit, LOL.
Okay, gonna have to post the links separately, due to time constraints... back in a bit.
