Implementing water-saving initiatives is a smart way to reduce utility costs.

Cost segregation utilizes the MACRS approach.

ALTA survey, utility survey, etc.$100k per building, I'd say not usually. 

I’ve heard that this neighborhood doesn’t really have any problems from a social worker but outside areas aren’t good. 3/4 units are currently rented at $900 each, renters pay utilities.

@Alecia Loveless is correct--tenants need access 24/7 to their electric service panel, water and heat, assuming those are individual utilities for each unit. 

Due to increased rates i did not refi so i did not get opportunity to see how an appraiser valued the half bathroom but the comps with same bathroom count had crazy valuation for the additional half bathroom.Taking under utilized space like a work area to add a br where the added br does not put you above the normal for the area can add value.Similar if a neighborhood is virtually all 3 br and 4 br properties and you find a 2 BR, it could be a value add to add the bedroom via new construction.  

I underestimated utilities in my early years, so I ensure those are properly captured (electricity, gas, water and trash).
