At some point, you're going to hit a point where you're seriously considering the scope of your business and how you want to move forward. Many therapists will be content working for others - in doctor or chiropractic offices or in spas. Others will be content to rent space or travel to clients. But others may aspire to build their own business and at some point you're going to have to decide if it's better to rent or buy your own building space.
You're going to have to sit down and seriously consider your finances in order to make this decision. Where is your business now and how much growth do you foresee in the future?
When you rent, you can move from location to location as your lease ends, upgrading or downgrading in terms of space and cost. If the economy tanks (again) and people decided massage isn't at the top of their list of things to buy, you may struggle for a bit but you have a way out. If your business grows more than you think it's going to, resulting in your need for a larger space so you can add additional therapists and services to the mix, you can do that, too.
Your own building, on the other hand, is relatively limiting. While you won't have to answer to a landlord, you'll have a mortgage and you'll have to pay property taxes. You'll also have more expensive insurance needs as you work to insure the building itself in addition to your personal property and your general liability needs. You'll also be 100% responsible for utilities and maintenance.
On the other hand, you'll have control of design, interior changes, landscaping, and more if you own your building. You could, theoretically, make alterations in a rented space, too, though - with landlord permission.
So, how should one decide?
You're going to sit down and take a look at your written business plan (you have one, right?). Look for the latest news and trends in real estate and in the massage business. Gauge how things are going and what you'd like to do to see your business grow.
If you're still not sure, find a financial advisor or accountant to crunch the numbers with you. Don't allow yourself to be jaded by your dream of having your own building. The costs can be astronomical and may not be worth it to you in the long run. Be realsistic about your expectations and you'll have what you need to make the right choice.
