I need to clean this table ASAP

So he is motivated to clean and make the unit ready to fill it as he wants it filled as much as I do.

Cleaning up the place seems to be the best.So is the only reason people do all these fixups is because they can't sell the places 'as is' ?

It does provide a clean definition.  

So I do not want to put carpet in as the floors will be much harder to clean. 

What do you think is happening underneath that shiny and clean looking fitting?

Wow this question is so vague I have no idea how to give specifics...On a 10' x 10' room (similar to your standard bedroom) I can remove everything down to the studs in one day.1/2- 3/4 day to rewire (simple cosmetic such as changing the number or location of outlets if you're actually changing the wires itself up to higher codes it can be 3+ days depending on how the house is wired and accessibility)1/2-1 day to insulate1/4 day for any windows or doors that would need replacing for the 1 room2 days for drywall (so long as the studs are straight and level)25 hours of taping (+/- 5 hours depending on the number of corners/edges) spread over 7 days usually front loaded 3-4 hours the first 2 days, then 2-3 hours for the remaining 5 days.2 days painting; 2-3 coatsflooring will depend on the product you're using but unless it's hardwood or laminate you can usually get it done 1 day.1 day trim and molding1 day clean and finishing touches.One thing that shouldn't be overlooked is the time it takes to purchase the materials and get them to the job site.Another is where you can actually do the work.

At what point is it legal for me to change the locks and start cleaning the place up so I can start to recoup my losses.

However, in my opinion that is much more of a business than a passive investment because there is a lot more day to day involvement (i.e. cleaning, advertising, changing rental rates based on day of the week/time of year).

It's in fine condition (usable, just needs cleaned).
