Purchasing a parcel adjacent to my primary residence. I am lost.

[Joel Mayer]

I am planning to purchase a parcel the is adjacent to my primary residence in Michigan. I am drafting a grant deed to be signed but, I am not sure what other forms I need to submit to make sure everything is ok. I have spoke to someone at the city hall and they seemed to think I needed a Property Transfer Affadavit and a Principal Residence Exemption Affidavit.

I am just unsure if there are other forms I should be filling out also to make sure that everything is squared away.

How would I go about making the parcel part of my primary residence so that it doesn't get taxed separately and just gets added to my land instead?
