-Get to know local code enforcement or inspectors.

It should be noted that wholesaling has been regulated pretty strictly in Pennsylvania and wholesalers have to have a real estate license now among other things so there's likely less wholesaling going on in Philadelphia as in other places. https://consolematison.com/2024/06/12/new-legislation-on-res...

Quote from @Tyler Battaglia: Forms and contracts are important, but you need to really understand them and know how to enforce them. 

Hopefully, new legislation will change things to entice more carriers to the state.I suggest you reach out to your local insurance broker (where you plan to invest) and explain what you are looking for in a rental dwelling policy. 

They rent below market rates, they pick bad renters, they don't have a good lease or know how to enforce it, etc.

Even small, common mistakes like renting below market, picking the wrong tenants, unwilling/unable to enforce lease terms, slow turnovers, or unscrupulous contractors can cost more than a good PM will charge, and that's before you account for your time and the stress.If you have the personality, I recommend self-management for anyone who lives within 1-2 hours of their investments.

If they are VERY professional, they will have their processes in writing as verification that policies are enforced equally and fairly by their entire staff.6.

Why do you want to do it in a city that has a lot of regs.https://buildingsaltlake.com/city-bulks-up-its-enforcement-o..."

Level of Review: Projects are required to submit a substantial amount of project specific information as part of both the application review, approval/legislative process and contract reimbursement process.

I don't see how any city/state could possibly enforce requiring proof that all work done in the house was permitted.
