I like to update electrical fixtures,switches,plugs I always replace old thermostat's with a newer digital model. example, if the house has older cabinets and your budget wont allow for all new cabinets simply paint them white and put new hardware on them if you have paneling/drop ceilings remove them if your budget allows if not at least paint the paneling newer decorative (faux tin cieling look)drop ceiling tiles can add some appeal what you want to do depends on your budget and what you must do to sell the home. new homeowners usually like updated windows, paint, carpet, kitchen,bath again what you can do depends on the budget. is this flip/rehabb for low,middle or higher income family?

Guess we need to figure out what the property is in question.Tons of different type of modularBOCA, panel, singles, double triples, manufactured, everyone calls them something different and they all have different construction and design features.   

It's possible you mis-interpreted what your agent meant when they said you could renegotiate after inspection (usually that means for major issues like dangerous electrical panels, structural issues, partially collapsed cast iron sewer line, etc. that weren't obvious at the initial showings, not superficial things like "the AC is rusty" or "we should replace those ugly fans").

I have two Federal Pacific breaker panels that need to be swapped out for safe modern panels in a rental property near UC, and a few extra circuits added. 

., kitchen, bath, carpeting and paint, bring it up to code, such as a new panel to replace the old fusebox.

They jam and if not fixed they will crack the top panel of a aluminum garage Door.

Install (4) 6 panel doors = 6 sets bi fold doors. 14.

You may need a panel upgrade and that will cost at least $2,000. 

I have noticed whilst driving around a small ground floor apartment, it appears to be unoccupied, blinds are closed and i can see mail piling up between the glass door panel and the curtain over the door.

.- There are solar panels on the roof are hooked up to Unit #2 (my unit), therefore I do not really pay much electricity, or heat, since it's electric baseboard.- I have a gas stove in Unit #2, and Unit #1 has electric stove.- I will most likely be renting out Unit #2 at some point in the future.Now, you can tell that everything is sort of different for each unit and not standardized.
