I screwed up the staining on some cabinets.

is it stained now or painted.

Personally, I'd wait to remodel until right before sale so you can advertise it as newly done and also potentially save yourself the headache of repairing when tenant ruins the cabinet drawers (makeup stains, hot curling iron burns, even had spilled cleaners that sat and damaged inside cabinets).  

I've visited the property and it appears to be cosmetic (stained carpets, dirty toilets, sinks, tubs, paint), however I am taking the $16k with a grain of salt.

Kitchen remodels can range drastically in price for many factors: location, size of kitchen, selection of wood and stain, hardware, appliances, and counter top choices. not to mention a retail price given to a homeowner vs.

I quite often buy the unfinished ones off the shelf and then paint or stain them.

If it's an older home with already stained garage floor, I'd not be as concerned, but if it's a newer home with a nice clean garage floor except for the tenant's paint, I'd make it right and charge the tenant.

GPA makes no difference, the more social you are the more people end up in your house.Loud music, underaged vistors, beer stained carpets, fights, none of which were our fault... werent located any where near the school either.college kids = bad news

She also did not clean the carpets and now have mud and grime stains that now I must hire someone to remove.

The dogs went to the bathroom outdoors but left dirty, oily, stains on the lower walls and carpeting.
