Boats increase in size geometrically, to the cube of the length. A 35' boat is about 36% bigger than a 30' boat, even though it is only 16% longer. The sails are more difficult to handle, as is the ground tackle. Anything smaller than 30' is generally too small to comfortably liveaboard.
The Alberg 30, one of my favorites, is actually a fairly room boat for its size and used by at least two bloggers I know of as a liveaboard for couples with a single child.
For instance, an Alberg 35 weighs in at 12,600 lbs., and has a 100% sail area of 545 sq. ft. The Alberg 30 weighs in at 9000 lbs., and has a 100% sail area of 410 sq. ft. Handling the mainsail on the Alberg 30, which is 221 sq. ft. is fairly reasonable for a single person. The main on the Alberg 35 is approximately 50% larger, and significantly heavier and harder to manage. Another problem is that boat costs generally go up with the length of the boat. An Alberg 30 averages about $16,000, while the Alberg 35 averages about $26,000.
Also, many of your cost: hauling out, dockage, painting, storage; are related to the length of the boat... The equipment on a larger boat is also more expensive... the winches are larger, the ropes are heavier, etc.
Finally, for a relative novice, a 35' boat may be a bit too much to handle, especially short-handed.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
