The cosmetic renovations are the easy part, the part you really need to understand during due diligence is what systems you need to modify and update-pluming, electrical, structural, roof. 

@Maurice Stewart You will need two different contractors, one to separate the pluming in the house (think local licensed plumber) and a second plumbing utility contractor to install the meter on behalf of the SWBNO (they no longer do this).  

and just to be clear, the boundaries of a federal superfund site are determined by how far the contamination has migrated and is not necessarily limited to the source of the contamination. there can be groundwater plumes that can extend for several miles so that all of the properties sitting above the zone of contamination would be considered to be located within the superfund site but that are not responsible for the contamination but simply impacted. very different calculus than if the parcel you are considering is a source of the contamination  

The finished unit is -1600sqft, 3 bedroom and 2 bath Second units is 1400 sqft - unfinished but has electric and plumping third and possibly 4th units - just wall, needs electric and pluming.

If they determine it is a plumbing issue, they dispatch a pluming expert.

The scope resulted in our discovery of improper pluming, cast iron belly and a broken mainline.

I did the Sandwich lease Option with Bridehouse where they will be the middle man and handle everything and even pay rent if the tenant does not or the house is vacant.Bridgehouse failed to collect a security deposit when the lease was signed and now have stopped paying me because the tenants stopped paying.The tenants reported a pluming issue to Mario and neither the tenant or Mario got a Plummer on-site for 3 days (all without my knowledge) which caused sewage backup in my house.

Further away it shouldn’t have much impact assuming the area is good from an economic standpoint and the environmental impact doesn’t extend off site (like a groundwater plume that extends for miles).

How/why would they be alerted to any necessary repairs (i.e. pluming, electrical and other major repairs) on a residential property?

Am i missing something is this Enough information for a typical buyer hi ( buyers name ) i think i have a property you may be interested in the property would not need much, update the garage for 5k. new carpet in one unit a year ago , the other one may need updated carpet 800$ the roof and foundation are in good shape as is pluming and electrical, the tenets have been there for 4 years and they don't want to leave. arv 130,000 maybe more, rents currently 1,300 that's 15,600 annually with sewer, electric, insurance,trash, taxes are 668$ about 3748 in yearly expenses 11,854 in profit with cash purchase and 12% ( ROI ) repair cost 5,800property cost $95,000amount needed: 101,100 with closing cost 1127 e 5th , CASPER, WY, 82604PROPERTY DETAILSUNIT: 1Current Rent: $800 Occupied: Yes Bedrooms: 2 Bathrooms: 1.0UNIT: 2Current Rent: $500 Occupied: Yes Bedrooms: 1 Bathrooms: 1.0Beds: 3Heating: Forced airHeating: GasFinished basement 778 sqft basementAppliances included: Dishwasher, Range / Oven, RefrigeratorFloor size: 1,318 sqftAddition size: 778Unit count: 2Multi FamilyRoof type: MetalExterior material: WoodBuilt in 1917Lot: 3,484 sqftParcel #: 33791022601400Parking: Attached Garage, 2 spaces, 288 sqft garageLast sold: Jun 2004
