if you are near the northern neck, stop by and I will give you a tour of our little world. We do weeks at a time, working out the kinks, and hope to be full time when my son graduates college.
Our biggest challenge was what to do with all the "stuff", but since you are young, you will not have quite so much.
As CaptForce says, the boat really cuts down on the shoreside expenses. We use our bikes more, walk more, get out more...it is almost a 1/4 mile to the bathhouse and back to the boat...
We enjoy the weather noise, the wildlife - although we often startle them and they us, the water action.
Down side is cold rainy days in may can still be raw...but then you know you are alive.
We almost took the plunge in 1984, dern real estate agent found a house we could afford, and often wish we had.
All the best
