I’m looking into an FHA loan with a 203k for renovations and be a live-in landlord.

Are you flipping or land lording?  

I am participating in Landlord Cooperations Program in Philadelphia provided by PGW- gas company.

That being said the city provides a great free class for landlords you should take and you will need to take it if you move out.  

At the least, you will have a bigger pool of lenders competing for your business if you finance under your own name.

Mostly because my wife said “we don’t want to be landlords!”

In that scenario you most likely will need to purchase a homeowners/landlord (depending on use) policy in your name then list the seller.

And househacking a multi allows you to see if being a landlord is something you are cut out for.

I am a mid-size land lord with fewer than 50 units. 

The larger you go up in center size the PM fee can come down to 3% in some cases.CAM ( common area maintenance fees ) typically cover property taxes, landlord insurance, PM fees, maintenance to the building and service contracts.Some tenants instead of a NNN leases have NN lease or a gross lease.
