According to an AARP survey, nearly 90% of those over age 65 want to stay in their homes as long as possible. But in order to do this, it’s necessary to have a housing plan—and a support system—in place to ensure that they’re living safely and independently.

Here are 6 things that aging singles or couples—and their children, other family members, or caregivers—should keep in mind when assessing the living situation.

1. Develop a real estate and housing strategy

As you plan for your later years in retirement, you should have a strategy for how to leverage any real estate assets along with a plan to support your need for future housing. Real estate is an asset often used to fund retirement and to help pay for long-term health care expenses. Some people find it necessary to sell the family home to pay for higher levels of care or senior living accommodations. Some decide to sell after a spouse dies. Others may have a family member who moves back in to help take care of both the aging parent and the property. Whatever your situation, it makes sense to work with a financial advisor to help determine the role of real estate in your overall financial planning.

As people age, housing and caregiving go hand in hand. If your loved one will require higher levels or care, you’ll need a housing strategy that can serve their needs. Keep in mind that what works today in terms of independent living, living with relatives, assisted living, or skilled nursing care may not work for you or your loved one indefinitely.

2. Explore the benefits of staying put

There are many reasons why aging in place can be a win. For starters, staying in your home can be less expensive than moving to an assisted-living community. There are the upfront costs of moving, an often steep entrance fee, and monthly payments for room and board, which can easily top $3,000 a month.

Even more important are the psychological payoffs of not moving away from one’s friends, medical professionals, and faith community. Though these factors are hard to place a financial value on, they are a vital component of healthy aging. In fact, the single most predictive factor of whether you’re going to age well—meaning be able to be independent and live a long and healthy life—isn't money, and it isn’t even necessarily your health. It’s your social connections, which may get lost if you move.

3. Do a home safety check

The first step in an "aging in place" plan is to run a complete safety check of your home. There are some hazards that you might take for granted—for example, furniture obstructing pathways or stairs. Walk around the house with an eye for any potential hazards that might cause trouble should you loved one’s vision or mobility begin to deteriorate. Then make any necessary changes or hire a home modification professional to help.

The good news is that many of the improvements that may make it easier for an older person stay in their house—such as raising electrical outlets to make them more accessible, or installing brighter outdoor lighting—aren’t expensive.

Other improvements to consider for an aging loved one are: installing secure handrails alongside any stairs to the front door, switching doorknobs to levers, adding automatic lights to hallways, removing rugs that might become tripping hazards, and placing grab bars in the shower. There are plenty of easy and relatively low cost options to modify a home. The sooner you start preparing, the better.

4. Assess transportation

Driving may be your lifeline to independence, and coming to the “I don't think I can drive” moment is tough, but it can’t be avoided. If you are at the point that you can no longer drive or walk to the grocery store or reach other important services, consider other transportation options.

If you have access to public transit, great. But it doesn't exist in a lot of places. Meanwhile, the driverless car may still be a few years away. So you may need to make other arrangements, such as ride sharing with friends and neighbors, or transportation assistance that many companion-care services offer.

When it comes to groceries and getting things like prescriptions filled, automatic delivery or online delivery can be a great option. A family member or friend can help manage orders and accounts and can track order history to help make sure you are getting what you need.

5. Ensure a supportive community or network

Isolation can be a stumbling block to aging well. And it can creep up slowly. No matter how safe the inside of a home is, if there isn’t enough interaction with a community, a plan can fall apart.

Part of aging in place successfully is being able to stay connected, and not fall into the depression that many people experience because they are isolated. Getting comfortable on a computer so you connect online with your children, grandkids, and others is a good strategy. You might also investigate some of the companionship services available in the community, through websites such as Caregiving.org or tap into local Council on Aging resources.

Pull together a list of friends and relatives who can take you to a doctor’s appointment, or someone to help with errands. If your family doesn’t live nearby, you may want to have a pipeline to neighbors you can call for periodic checkups, especially if you live in an area of the country that experiences power outages and severe weather.

6. Make it an ongoing process

One of the “living in retirement” myths is that people think they can make a plan once, and they’re done. Instead, this is something that needs to be reviewed regularly by you and your family member or caregiver.

What if you experience a health event, such as a bout of pneumonia that requires a lengthy hospital stay, or a fall that affects your cognitive ability or mobility? These are going to be very important points when you have to take a look at whether the plan you put in place is still going to work going forward.

Are you a concerned friend or family member? If so, check the home of your loved one after it is retrofitted and keep an eye open to see how your loved one is adapting to the changes. You may want to look out for any unexplained bruising on the aging person’s arms or legs, as these can be an indicator that they may be having trouble moving around. Also, look around the home when you visit. Is there a pile of mail? Are things in disarray? Check the refrigerator. Is it bare? Is food spoiling?

In an ideal world, we will age gracefully in place, but that doesn't happen very often without careful preparation. Take the time to sit down and get the aging-in-place conversation going.
