Most small businesses start out leasing space and taking advantage of the lower monthly costs and flexibility that renting provides. Many remain lessees for the same reasons. Others, however, reach a point at which buying a building makes more sense than paying a landlord a monthly fee.

How do you know if you're at that point? By taking a look at your business's financials and your plans for the future.

Rosemary Camposano, co-owner of Halo Blow Dry Bars, Inc. leased space for the first three Halo locations in California. Now that a fourth location is set to open, however, Camposano is considering a building purchase. Here is why now is the right time for Halo:

Equivalent cost

At Halo's fourth planned location, the monthly cost to rent and the cost of a mortgage payment on the property is about the same: $5,000 – 6,000 per month. Yet with a commercial mortgage, Camposano and her partners can build equity in an asset — a building.

When the cost to lease is the same as or more than the cost to buy a building, it's time to seriously crunch the numbers.

Acquiring collateral for future lending.

A more important reason to buy is the need for assets through which Camposano can acquire additional funding. With Halo growing rapidly, the company anticipates the need for taking on debt in order to continue to open new locations.

"Almost no bank will loan to a small business if your business has no assets," says Camposano, based on conversations she has had with several banks. But owning an asset like commercial property "becomes an anchor for other borrowing opportunities," she explains.

If you foresee significant future growth that will require investors or loans, building an asset base through the purchase of a building can make a lot of sense.

The established business is profitable.

Until you've been in business for at least three years and have achieved steady profitability, committing to a building purchase is risky. Halo, fortunately, has done both.

"It makes all kinds of accounting sense," says Camposano, since Halo is beyond worrying about survival; the company has achieved steady revenues that are unaffected by economic cycles or seasonality.

If your company is well past start-up, with a consistent revenue stream and an interest in fortifying the asset side of your balance sheet, investing in a building may be a wise move.

The need for space is fixed or stable.

Companies experiencing or anticipating rapid growth that will cause a need for more floor space may want to stick to leasing. If your need for retail, warehouse, office, or manufacturing space is ever-growing, committing to operate out of a building with finite square footage may not be appropriate. One of the major advantages of leasing is the ability to move or expand in sync with the business's needs. Once you buy a building, your flexibility is diminished.

Only when your business growth has stabilized, or your need for space will be met by opening additional locations, should buying property be considered.

Camposano sees buying a building as an important next step for her company: "It will act as an accelerant for business growth."
