Not once you take into account any tax obligation to realize that value in cash.
You are correct I am ignoring tax implications because those will vary by state, by an individual's tax brackets, and rental costs including MFs. So, you can adjust the math by 10% to 50% as you feel. I won't ignore them in the rest of my post below, but I probably will in the future because of the great variation.
If cash is the great equalizer, then why buy timeshares? Seems to me like buying a timeshare is one of the worst things you could do with your money. For most people, the cash outlay to buy timeshares is very high. Most people have spent thousands or tens of thousands of dollars to buy timeshares. For most people, it is probably better to work at your job or invest in the stock market long term and use that cash to pay for your vacations.
Agreed...not necessarily the best financial decision if you amortize in the initial costs. A decent decision if you look at vacation costs against MFs. For me, it was a great lifestyle decision & I didn't buy the first one until I was in my mid-60's.
The only thing that is constant with owning a timeshare is paying maintenance fees. You pay that whether you use the timeshare, rent the timeshare, exchange in abound, exchange in II, bank usage to a future year, or let it go unused.
If you buy resale, you can justify the cost of a timeshare more easily. But rental values should matter in both decisions to buy and decisions how to use. For example, one should hesitate buying a timeshare in a location where rental values exceed maintenance fees, and it's less problematic and more attractive when rental values exceed maintenance fees substantially.
And here is how rental values can factor in a usage decision... Say you own an enrolled 2BR Platinum at Newport Coast Villas (MF=$1600, rental value of a summer week is around $3500, and you have a confirmed summer reservation). Now you want to exchange to go to Waiohai Villas on Kauai (all 2BR resort) for the same or earlier week in the summer. You can:
1) Try with Interval with request first (something you couldn't even do if Kauai reservation was later than Newport)
2) Trade in Abound for 3475 points, but it will only get you 5 nights Island View (4 nights in OV) at best due to MVC's preference of Hawaii weeks. Will need to rent extra points for 7 nights.
3) Rent out the Newport week (for around $3500) and rent the Kauai week from another owner (expected cost $4500 - for OV). Possible tax implications matter.
4) Direct exchange with another owner - not likely to happen.
The II option is the cheapest because it's a 2BR for 2BR with just the II Marriott to Marriott exchange cost, but you don't control the view you get, and you may not get the exchange at all. The Abound option would require another 1400 points (~$1000) for IV and 2400 points (~$1700) for OV, and is a reliable exchange at 12-13 months out. The rental option costs you an extra $1000 (maybe $1500 after taxes), but you can probably get an OV for that price and maybe negotiate the cost down. And now you can decide what to do... In this case, I would personally go with Abound for either IV or OV, even if rental beats OV by ~$200, because of convenience and certainty. Other may choose II because it's much less pricy. And someone whose week is not enrolled in Abound, may go the rental route over II due to more certainty.
In the choices above maintenance fees are irrelevant because you pay them no matter what you do for as long as you own your week. You can use them to figure out the "total cost" of your Hawaii vacation, and they will perhaps reduce your taxes, but they don't otherwise matter for the decision you make. The rental option is exactly that - just another usage option. In this case, it may not be superior to Abound. In other examples (like if I used WKORV instead of Waiohai as an example), it might be.
