my condo on the market

I am currently living in a small 2 bedroom condo in upstate New York. There are seven units in the complex. Six of the units are residential with only one commercial. One commercial unit and three residential units are leased by the owners to tenants. Three residential units are occupied by owners. My real estate agent told me that it will be very difficult for potential buyer to get financing if I put my condo on the market. Is this true?

It depends on how it's zoned. That sounds like a confusing situation. I would consult a Realtor or Mortgage Broker as they know more than most!
