Business trip tax questions

[Ken Livingston]

So I am in another state where I just purchased a duplex on Monday. I drove here and have of course have saved my gas receipts. My question is, is everything on this trip a write off? I am solely here to do some work on the property, meet with the new PM, and to have a sit down with my realtor to discuss possible future moves. 
  can I write off all the meals I have had while here? Even if by myself? 
  thanks in advance
