If you love to vacation in the same place each year, or like to visit a favorite destination more than once a year and would rather not lug suitcases with you each trip, you've probably considered a vacation home. If you have the funds and the plan, buying a vacation home in your 40s or 50s can be a great help to your retirement nest egg.

How to Buy

The decision whether to buy a vacation home or continue renting is about lifestyle and disposable income. As with a year-round home, owning your retirement property means that part of your vacation budget is being applied toward maintaining and updating your vacation home. That will work fine if that's what you're planning for. But if owning the vacation home eats into other things you'd like to be doing, then it might not be your best option.

Fortunately, your vacation home purchase won't need to be made under the same pressure that went with your residence purchase. You can try before you buy, by visiting the location as a renter before you commit as an owner. As much as possible, make your rental visits mirror what you're planning for as an owner. If you're planning to buy because you'd like to visit the location more often, try multiple visits as a renter first. If you're buying to become part of the community, rent and start your involvement before you purchase. Dollar for dollar, you might spend a little extra doing this due diligence, but a little extra research will help you choose the type of situation you want.

Costs to Plan For

Make sure your vacation home purchase stays exciting and enjoyable by planning ahead for extra costs. Just because you're only there part time doesn't mean you can ignore regular maintenance and the costs of keeping the place up to date. If your second home is a condo, be involved in the condo association just as you would be at home. Set aside funds to cover off-seasonal chores and to open and close the house if your place isn't year-round. If you plan to have seasonal renters, allow for housekeeping, extra maintenance, advertising, and an accountant to help you work out the tax return — at least for the first year until you learn how to do it. The best times to rent are usually the times you probably want to be there, too. Make sure the finances work without factoring in rental income.

Tax Advantages

Don't take equity out of your residence to buy a vacation home. This might be attractive at a time when home prices are rising, but it is something like financing a vacation on your home equity line — a risk that could leave you hanging if and when the market falls. If you decide you can afford a loan to buy your second home, use the second home itself as collateral. Taxpayers who can itemize their deductions can deduct interest on mortgages against a second home the same as they do the mortgage on their first home.

Keeping It in the Family

If your family owns a vacation property that all would like to share, or you're thinking of buying a property with other family members, talk to a real estate lawyer or your estate attorney to see whether it would be better to own the property as partners or whether a more formal arrangement such as a limited liability company might be a better idea. Your attorney will help you assess the amount of liability the property might create for each owner and will help you draft a use agreement that outlines everyone's rights and responsibilities regarding the property. Try to set up an agreement as soon in the buying process as you can to avoid misunderstandings and hard feelings later on. If you already own a property with family, a visit to an attorney should be a top priority.
