Once you decide on which you prefer to pursue network with people in your local market that can help you accomplish your goals (for example network with lenders if you need financing, title companies, perhaps wholesalers, other local investors, inspectors, etc).

Do I need to contact some city home inspector?

I developed a very good relationship with the case managers and the inspectors.

While some over zealous or power tripping inspectors give them a bad reputation, we are all better off thanks to building/housing standards enforced by inspections.

Do you know there motivation for selling, and have you gone through with a building inspector yet?

I use conservative estimates on what I see and later refine with with my inspector.

You could do that here by getting an inspector to comment on the lead remediation requirements in your area even in the absence of taking dust swipes for lead.

Can an inspector use this to inspect the roofs and gutters instead of climbing up there?

I would definitely hire a licensed property inspector-off angies list hopefully.

Would some building inspector notice this code violation?
