My Fidelity Investments retirement calculator web page says 25% of us live to 93 years of age. To me that means I may need to stick it out for 40 years! I gotta know where my dollars are going.
I hope to estimate annual depreciation, then figure it on a monthly basis like other costs. It seems reasonable to figure it as percent of the value of the RV lost in a year. Since I don't know that percentage very accurately, I use a high depreciation rate and a low depreciation rate.
I'm also trying to compare it to the stick & brick alternative. I might be willing to spend more on the full-time RV lifestyle, but I would want to know the costs going into it. The range of depreciation rates for the RV turns out key in that comparison. Which is why I'm probing around for guidance.
If the RV costs less than the stick home, that's money I can put in the bank and earn interest on, which helps to balance the equation.
I'm going to try to get fancy here. I'm using Excel to help me model the comparison. I'm going to try to like to a copy I've uploaded somewhere and hope folk can access it...

The alarming fact is that with just 10% per year depreciation, figuring 5% per year return on that bank account, break even is a 3 to 1 ratio - $300,000 home equates to a $100,000 RV.
I've considered other budget factors and they tend to be comparable and/or cancel each other out. And of course you can't place a value on the time spent with the wonderful folk out there...blah, blah.
Still, I would appreciate it if some people would check out this analysis and comment on the assumptions and calculations.
