After home inspection 3 big ticket items came up:- Major repairs in roof.

Using a DCF model, you can project out hightened rent collections for a period of time, say a year.

The biggest issues we faced was equipment breakdown as customers routinely abuse the equipment  the most common repair ws due to over stuffing the washers and using the washers to dye items.

If ANY personal items of the resident are left behind,  either a signed declaration from former resident that they have moved out and release any claim all remaining items - enumerate any large or potentially valuable items - (get it notarized or ensure signed with witnesses present)  or preferably,  ensure property is completely empty, interior and exterior,  of resident belongings.    

Replacing some floursecent lights or 80s/90s spotlights with LED recessed lights is a cheap way to enhance the look of your unitsI can't comment on these being wise investments for YOU specifically but they are items to consider based on what your market is doing.

If the deal materializes, this will be the first time I close outside of the traditional agent-based model.

These are some of the major items.

As to the advice of trying to sneak in the rough electrical wiring while still getting permits for the other large items, I find this advice is not very practical in most circumstances, the inspector will be there to inspect your other permitted items and there is no way to hide rough electrical rewrite of a home.

I enjoy tax research, tax planning, financial modeling, and litigation support helping attorneys in family law, business valuations, etc. 

Unless you have specifically hired the inspector to give you an OPINION on a home, then what they should be doing is "calling out" items of note . . . which are present in EVERY home, regardless of age or condition.The inspector ALWAYS works for the person that hired them; either the buyer or the seller.
