Assess a cleaning fee to remove any odors or stains.

I might have to replace the carpet for second/third floor there were stains.

The asking price is $25,000, and it needs 10-15k in repairs, mostly cosmetic (i.e. resand/stain floor, drywall work, paint, etc.)

I stain it and then paint a 16 inch grid/groutline to camoflage the seems, and oil base floor varnish as a topcoat.

Basics of slopping floors, cracked walls or ceilings, doors that don't close, water stains, sagging roofs and identifying load bearing walls are things you should understand.You don't need to be a certified inspector but usually knowing basic construction techniques and standards will allow you to inspect well enough for an initial assessment.

The kitchen cabinets need to be stained or painted.

For example, painting a wall or room; hole in wall or door; replace carpeting due to stain (not groom normal wear and tear).Gives them something to think about. 

i'm also steering on the 'up' side - despite the fact that a realtor's photos often get heavily criticized by others if they didnt put the lid and seat down in the pics - in showing homes, tenants and buyers do want to see that the toilet doesn't have unremovable scrapes/stains that they will have to cope with most everytime they step into their bathroom.i was on the fence cuz agree things with doors lids are supposed to stay closed when not in use, but then again we do leave bedroom doors open, lights on, etc so viewers have easy access without having to 'touch' although most of people in this area so far seem to do alot of testing like to see if hot water comes, undersink area isnt wet, and toilet flushes easily.

I "Repaired" a bleach stain in a maroon carpet with a variety of colored permanent marker (Quite well I might add). 

Yes we're stubborn, but even if we broke even, what has been done most cannot do.
