Hi Papa, Inspectors are not FHA or Conventional - this is the type of loan you are getting. You may be thinking of Appraisers (they determine the value of the home and the bank orders that).
You just need to find a Real Estate Inspector and let them know you are getting a Conventional loan on a Mobile home and need a home inspection. If the home has a septic system, you will need an inspector who does septic inspections or who contracts out for that portion of the inspection. Best wishes to you! Laura Rosales-REALTOR
