it all depends on the home certain style homes are known for certain things that I look for
I will.explain what I look for personally. starting interior but first things I do a initial.walk through and look closely to the ceilings basically checking for leaks... if leaks are present then I find out why.
pay special attention to skylights and chimneys. Continue this into the attic
While doing this I check to make sure each room has a heat source.
I look at the windows. New old etc.
Then flooring
. how many layers etc. Look at power outlets. Lights closest in bedrooms. Bedroom count, also I look to see if another bedroom can possibly be added
Continue into the basement furnace, boiler?hot water, wiring, structure of the home, floor joists, evidence of insect, foundation walls if it's a duplex I look for seperate utilities.
Smell.mold ?
drainage, etc. updated wiring, plumbing etc. ( I've seen water pressure tanks with in my city limits and to me that's a hell no). Look at basement walls for evidence of water. Look for sump pump. Work.done on a home after it was constructed can tell you the story about why it was done if you pay close attention.. Weather it was a good job or bad makes a big difference if one thing is cobb job then they all are most likely cobb.. if I see someone who added a 5/8 or 3/4 inch water supply rather than installing a pressure tank in the city it tells me this guy probably new what he was doing.
There's so many variables that it's impossible to explain with complete accuracy for a particular building.
.. after this is done I work my way outside.
is the house on a hill? How is the water.going to drain away from the home etc. Roof, cladding system,
I hope.i havent left anything out but i feel as though i have a pretty good system for residential and in have been very accurate with my estimates as.far as work that needs to be done on the home.
One thing I require om homes that have been vacant a while is a pressure test on the water supply.. gas will probably be required by utility company but water is not and that has saved me from making a 100k mistake in the past. I put that in the contingency column.
I think we are pretty close on what we look for
