If this is a property purchase I'd make sure to double check the environmental piece in case there are underground fuel tanks that need to be remediated.

There's a few phases - For info for buying, you'll need Leases and terms, breakdown of costs (what is tenants responsibilities and what is landlords), breakdown of CAM (Common Area Maintenance), each units price per square foot, tenants revenue to rent ratioOnce you go into due diligence, you'll need balance sheets, surveys, P&L, and tenants' sales reports for two years. lease docs and amendments including any statement regarding oral agreements, tenant estoppel agreeing with what you've been given, any open permits or zoning issues, environmental reports (don't want to find out later an old gas station or laundromat was there before), owners current budget, a complete list of all property stating who owns what and who is responsible for the care.

The violation or enforcement of those portions of any law or government regulation concerning:a. building;b. zoning;c. land use;d. improvements on the land;e. land division; orf. environmental protectionNow I haven't seen or read the OP's so I don't know if it's an HO's policy or if there is an exception to coverage which might affect the underwriter's liability if it's otherwise provided. 

@Sue HoughI actually was an environmental engineer looking to get in to the solar industry a few years ago.I absolutely LOVEEEEE the solar tiles.

As far as commercial goes you will need to do a few more inspections than residential like Phase 1 environmental, water pressure, septic, commercial building inspections and depending on the age of the buildings lead, asbestos etc. 

DWQ, Army Corp or any other environmental requirements or permits.

@Devyn CaraballoI’m in New Hampshire and our Dept. of Environmental Services has a fund homeowners can tap into to help pay for the clean up of leaking oil tanks.

If that's the case, you can't do any renovations until you have it professionally deleaded or it would be flagged for Unauthorized Deleading and you can get fined and the property would never be able to get a Lead Certificate, only a letter of Environmental Protection that states you did illegal work, got caught, then had to pay a professional to clean up the mess.

., demolition of old drywall/etc, remediation, materials for new drywall/paint, labor, post construction environmental test, etc).It's a fair question about the amount of time that elapsed.
