As for the leases, would you recommend keeping the tenants, potentially raising rent, and extending the lease to a long-term rental, or would you recommend finding a new tenant? 

There really aren't any agents that do just leasing for people of residential homes 

Primarily rented to military- never had a problem, required to end lease or evict. 

I will use the rent by room strategy for a year, then move out and lease the condo under 1 lease.Does anyone have any advice about condo hacking, or can anyone describe their personal experience?

Their lease is up end of day today and I was just at the house- there is no way all their stuff is going to be moved out by EOD.

If you want it to be a business name, then I recommend you set up an LLC, transfer ownership to the LLC, and then change your leases to match the new owner name.What is your reasoning?

that we’ve learned in our 24 years, managing almost 700 doors across the Metro Detroit area, including almost 100 S8 leases.

only the appreciation gained during the leasing period?

I wish to make it official and get them on a lease. 

Just add the Tenant's Rights and Responsiblities to the end of your lease and have them sign both at the same time.
