The need for building permits in the counties is limited to plumbing, HVAC, & electrical. 

 $5,000 to hook up water and electric.  

The insurances like AAA are strict on the paint, roof, plumbing, electric etcThe houses are in Stockton, California.Thanks

For example: Landlord will pay for electric, water and sewer charges up to $100 per month.

Subtract $350 for HOA dues, maybe another $400-$500 for electric and internet, and potentially water bills. 

Virtually everyone has used an electric range or oven in their life but lots of people have no experience at all with gas anything. 

Bad electrical is dangerous.  

If the home is 100 yrs old, I'm assuming it's a definite gut which is going to require new plumbing, electrical, heating, cosmetics.I spent about $140K reno on my multi family in the heights on NY ave and there were massive problems with it but it was a gut to 3 units & adding 2 bathrooms, 3 brand new kitchens 4 bathroom reno in total, all new flooring, sheetrock , insulation, framing, doors, electrical, plumbing, paint, parts of roof etc.

The GC can handle the entire project, coordinate different subcontractors and make sure the project is completed per building codes - especially if the rehab is complex or involves multiple trades like plumbing, electrical, and carpentry.

To avoid the risk management/insurance that comes with tenants' wood fire use:I'm thinking to seal the chimney cap on roof and run a cord putting an electric Infrared heater fireplace in there, so they can still open the glass and get heat and watch TV over the mantle, but can't burn anything or have any flame.
