The only thing is  if we installed washers/dryers, tenants would have access to a rear alleyway as well as the electrical panels, fuse boxes, main panel, water heater, and phone connections.  

Probably more like $30-50k or more to do stuff right such as: replace roof, repair foundation, replace water piping, put a new panel in.

Challenges still facing:Electrical panels and HVAC systems are not split, so I pay for utilities and build that cost on my rents.

@Steven Gesis this may be too out of the box, but solar panels, composting, expanding recycling centers.Depending on market, millennials are much more environmentally conscious.

New metal roof New gravel driveway New shed and pump house New deck Exterior paint New electric panel Rv pad with water sewer and electric hookups Interior: flooring, Sheetrock, paint, painted kitchen cabinets, hearth, windows and doors, bathrooms, walk in tile shower, mowed entire 7 acres.

The most critical things are roofs, attics, electrical panels, crawl spaces, basements and foundationsAny brokers/agents think it’s ok to look and inspect at the same time if it’s a house I have interest in.

Wind turbine / Solar rent (cons: not enough knowledge, do I need to buy all the equipment and sell energy back to the grid, or do companies rent the land and put their own equipment up?)

The repairs are large items such as electrical panels ect. there's an electric panel that needed to be inspected the 1st time around but even on the 2nd attempt it was not able to be inspected because of the water flood condition I'm worried about paying the inspector because this would be the 3rd time in paying for the property to be inspected which I  dont believe is fare since there was time for the items to be fixed the 1st time around.

This might be SOME rewiring, plus a new panel, meter base, riser, and weatherhead (say somewhere between $4,000-$8,000) or it could require a total rewire (in excess of $8,000).  

The city of Los Angeles is not currently requiring solar for new ADUs.
