I would mention to Tenant B that I was visiting Tenant A and smelled what seemed like marijuana smoke coming from their side and remind them there is no smoking permitted inside the house.

The 4 guests smoked marijuana in the house (strong smell), broke a window blind and a picture, put a hole in the bathroom wall, chipped an end table and worst of all vomited on the couch and front porch.

If there are items of value left behind, or even personal items of sentimental value, I will follow the abandonment rules to a "T" to avoid any legal issues.

$540 is not unreasonable for a home of that size and the items you mention.

Like you, when I'm working with clients I highlight the key advantages of the conventional rehab loans (Fannie Mae's Homestyle and Freddie Mac's CHOICERenovation) are:- They can be used for investment properties- You can include luxury items- They have a higher limit – $806,500 in most places.Jeff

I'm wondering how much specifics I need to include for each line item. 

On June 7th, we sent an itemized list of deductions via text; he responded on June 8th, disagreeing and threatening legal action.

Originally posted by @Eric Mayer: Not sure how much Marijuana you have been around, but some smells terrible and all of that can happen without smoking it inside.

One quote has the items listed, shows the price of each item as $0 and then has a final total. 

The poster was asking about broken/damaged household items and guests destroying a rental.
