The National Association of REALTORS® reports in its 2016 Profile of Home Buyers and Sellers that 12% of all buyers paid cash for their home.

Before paying cash for a home, a buyer should decide if they might put a loan on the home in the near future. It may affect the ability to deduct the interest on a mortgage placed on the home at a later date.

Homeowners can currently deduct the interest on up to $1 million of acquisition debt which are the borrowed funds used to buy, build or improve a home. Paying cash for a home establishes acquisition debt at zero. The only deductible interest to the owner would be home equity debt which is limited to $100,000 over acquisition debt.

Paying cash certainly seems like a simple decision but it may limit a homeowner’s ability to deduct interest on a future mortgage. You can get more information about this from IRS Publication 936 or from your tax professional.
