After a quick search I found "American Water & Energy Savers" website.

As long as the house is mostly liveable, has working heat, electric, plumbing and a bathroom. 

However, it is need of some modernization(kitchen is 30 years old, plumbing and electric need updated, paint, etc). 

I've been paying for about 4 years and they've promised to repair/replace hvac, hot water heater, electrical outlets, pipes, sewer/water lines between the house and the street.

Around Nov 2016, everything in stock market looked so expensive, even the troubled energy sectors enjoyed ridiculous rally without justification from fundamental.

I'm sure you can obtain the plan-sets for the homes from them when you buy (arch. engineering, electrical mechanical) to have them approved by your state.

., an electrical contractor will pull electric permit, plumbing contractor will pull plumbing permit, etc.

Either because of another full-time job, like Wayne mentioned, or you took on too many clients (compared to your available time, energy level, family commitments etc).Do you not have the fiduciary duty of obedience to obey lawful instructions from your client?

That should set you back about $100 and will provide accurate information on the age and estimated useful remaining life of the roof, plumbing, electrics and HVAC.

Bank turned off electric, sump pump couldn't work, flooded basement, and caused mold in house, had to gut all walls, ceiling, insulation, baths, kitchen, floor covering, everything to the studs, and needed new roof, new electric, new heating and most of new plumbingOther than that it was a slow year!
