. $25k sounds like a lot, but when you install new roofs, HVAC systems, hot water tanks, ceramic tile, new supply lines to angle stop valves, vinyl plank flooring in high traffic areas, carpet in bedrooms, faucets, fixtures, electrical panel updates, etc. it really is not that much and important if you plan on a long term hold.

HVAC, Roof, Electrical, Plumbing, Foundation, etc.).

Even if they have been in the house for 9 months, 12 months or 18 months, there is probably going to be more damage than you may think as opposed to higher-end properties.When many of my tenants vacated my lower income properties, they would tend to take parting gifts like electrical wiring, appliances and air conditioning units.

What or how extensive is the electrical work?

It needs new plumbing (cast iron), electrical, kitchen, BA, windows, doors, refinish floors, appliances, possible roof and remediation of a bunch of health inspector code violations.

In F areas I have seen this plus they take the furnaces, hot water tanks, electric panels, duct work and even the siding and gutters. 

or do you specialize in paint, framing, electrical, etc.?

Electrical panel?

There were a few issues since utilities were off for a few years, I needed additional permit and inspection to turn on the electrical.

Plumbing cost seems very reasonable and electrical does not seem out of line.
