I suppose there's nothing technically wrong with being a renter all of your life, but most people who buy a house are doing so to build equity. If you take the money you would spend on a mortgage payment, and use it for vacation instead, I'd be worried about your long-term finances. If, on the other hand, you rent and use the difference to build your nest egg, then it would make sense for you. Taking vacations at the expense of your savings is, as you probably know, not your best financial move!!!
I do understand the single part, though. I have a house and I do pay someone to do yard work and home repairs. Luckily, I have a friend who is a general contractor, and I keep him "on retainer" so to speak. Every so often I'll call and have a "honey-do" list for him, and he'll send over a guy who gets it done. Those are expenses you do have to take into account.
Good luck with your decision!!!!
