I am purchasing a home built in 1915 in Northern California, it is ideal location wise, size wise, looks wise, recently redone hvac, plumbing, electrical, etc.

I would say, "Hey, we can't wait to get the deal done, but have a question / concern about the plumbing in the bathroom.  

Some plumbing and electrical too.

If so, were permits pulled & were they installed by a professional5.Are any of the homes rented to students6.Is there a flat roof7.are there asbestos shinglesThe Year that the following were updated (either partially or fully) would be good to know:- Heating systems- Roof- Plumbing- electricalSome companies will not write properties with systems that have not been updated.As long as you are living there, the proper policy for a 1-4 family is a "Homeowners" policyc.

As a contractor I’d need to see foundation and plumbing option.

I would also look for other settlement evidence, around the base of the house, gauge plumb in the outside walls, that kind of thing.What you've presented, in conjunction with the fact that we don't know where it is so local people with local specialized knowledge won't be able to chime in, makes it unlikely that you're going to get a quality answer.

I am a detail-oriented person, and I also emphasize quality in any property I buy, particularly in regards to the foundational aspects - foundations, roofs, structural, plumbing, electrical, etc - the non-cosmetics.

Lots had terrible contract and businesses, But the rest like structural Engineer and planner, inspectors, electrician, large paving company, roofer (new commercial roof), plumbing and the rest came together as soon as they had to follow structure of a plan and permits.

Prospects I've seen might need new roofs, floors, siding/paint, maybe plumbing and electrical.

We essentially stripped the property down to the studs and focused a large chunk of our rehab budget on the structural and essential aspects (roof, HVAC, drywall, siding, plumbing, electrical, etc.), and put the rest of our money to work on opening up the floor plan and adding aesthetically pleasing features to the space.
