Can I provide my tenants with an itemized list of deductions (fair value) or do I need actual invoices from gardeners, cleaners etc.? 

Wedding planners, caterers, bartenders, cleaners etc are already in place.  

Apparently the vacant lot next door used to be a Martinizing dry cleaners and the chemicals had penetrated the soil.

You might even be able to throw in the perk of not having to clean, since you are going to have a cleaner come in after renovation anyway. 

Also, be prepared for the tribunal to just tell you that YOU need to accommodate them all by installing a very expensive air cleaner in your HVAC.CONSTANT documentation will be your friend in this matter.Good luck!

I am STILL finding dog hair in this property and it was cleaned thoroughly by professional house cleaners.  

I'm also thinking of remoteness and the amount of work you might have to do with it, being close to a home depot, etc, and yours and the cleaners convenience.

The best color is white, both for trim and for walls, as white paint can take the harshest cleaners and then touch up quickly if necessary.With that being said, of course the CHEAPEST paint available with the high-performance characteristics I want is always the best paint .Home Depot, through the Pro program coupons, runs in-store promotions where you buy two 5-gallon containers, and get the third five-gallon container free.

After extensive wash down with bleach and other cleaners, seal walls and floors to seal in any contamination.

Say on a corner lot where an old dry cleaners was torn down and an appartment building was built?
