The electricity is in his name.

Also, since I bought mine in a rough D area, I already addressed most all of my major issues during the rehab because I bought the house for 18k and spent 12k on hvac, electrical, plumbing, etc.

Properties built that old typically come with more repairs and cap ex, which can eat away your cash flow.Major things to look at for would be how recent the plumbing, electrical, HVAC and roof was updated.

Advise the tenant that you are very serious about rent collection and do not ever waive late fees.Procedure for allowing a pet or clarify that they may never add one.Where the electrical breaker box is, main water shut off and instructions on how to operate.You should have most all other policies and procedures codified in your lease agreement. 

Is plumbing and electric all working properly? 

Main house - Added 4th bedroom, new plumbing/electrical, new flooring, cosmetic refresh.

The 2nd and 3rd floor needs rehab work including, - Full Painting Flooring (Vinyl/Linoleum)- Replace Kitchen cabinets- Renovate the Bathrooms (replace tiles)- Drop a wall and make a corridor- Electrical throughout My question is, do I need to apply for a permit for all of this work?

This means that I pay for the water, gas and electric to cool the condenser in the summer.

I split off the electric meter for the ADU, so that will be billed separately.

Are water/electricity shared bills?
