I went for used once because it was clean and electrical stoves last forever.

Floors and walls need to be cleaned and painted.Photos posted on the investment, additional 2 of the current electrical panels below.

(Sullivan Township)-Should we do sewer/septic/electricity/water?

-- Would adding another unit involve having to upgrade the electrical system to meet current code?

(He had walls put up while electrical and plumbing wasn't completely installed) How do I know when is it time to cut my loses and sell or stick it out?

My deal points are:9 units1 House (3b/1b)8 Casitas (1b/1b)Rents $350 for the Casitas $850 for the house Electric Billed DirectWater, sewer, and trash included in rentLot looks to be permitted for four additional units (need to verify) Property taxes $3200 per year The sellers are older, retiring, and have not kept the best financials so I am working on projections right now. 

Many electrical boxes in ceilings are not intended to support more than a low weight light fixture and I'm sure no one on this forum wants a spinning fan dropping onto a tenant's bed.

The tenants as well as maybe electrical not sure how it’s set up yet I have yet to look at the property

YES, they will be checking MLS when the comments say, "New Electrical, new plumbing, new hvac", etc. 

I would have the tenants pay for electricity, and  water & sewer.
