A Relocation Specialist is trained to work with relocation companies which can be quite different that working directly with a property owner. It sounds like what you are looking for is a someone whose specialty is handling the buyer side of the transaction.
Even though realtors are compensated by the seller at the close of the transaction, you should be "hiring" your own buyers agent. Ask friends, coworkers, and church members for recommendations and then interview a few agents before selecting one. In your vetting process you should ask how many homes they actually tour each month. Many agents rely exclusively on the MLS Database and its photos and do not enter a home unless they are showing it to a client or listing it.
Ideally you want someone that you feel comfortable with and who is well connected within the realtor community. With the large inventory, it is next to impossible to preview every home that comes on the market, but many areas have regularly scheduled agent tours so that several homes can be toured in a short period.
Be upfront with your realtor and let him/her know what specifics are important to you. The more details you provide, the easier it will be for your realtor to pinpoint the properties that may fit. Most importantly, let your agent know that you want him/her to preview homes before you set an appointment to see them together.
Keep asking questions! If you are in the St. Tammany area, I'd love to interview for the opportunity to represent you.
