You should be happy that you had 10 showings in a short period of time. Now the question is what did the buyers that looked at your home think of it in regards to price, condition, location & floor plan? Finding out those answers will help you to determine which areas of your listing you have to change to entice an offer.
You might want to consider offering a buyers home warranty, or offering a credit towards closing costs rather than offering to pay their mortgage for the 1st few months. You may also want to give the interior of your home a once over look to see if there is anything you can do to make it more attractive & spacious looking: fresh paint, rearrange furniture, declutter, any needed minor repairs.That would attract more buyers for sure.
