They moved into floating homes and houseboats — and discovered a world of adventure and hidden expenses

• Forget buying a home on land — some people are heading for rivers and lakes instead.
• They're investing in floating houses, houseboats, and narrowboats.
• While the lifestyle has perks, it's not necessarily cheaper than owning a house on land.

Moving into their 360-square-foot floating home a year ago was a dream come true for Sarah Spiro and Brandon Jones.

The house, located on Fontana Lake in North Carolina, has loft-style interiors with high ceilings and windows all around.
