One of the property rights a tenant gets in a lease is the right to exclude others. 

Might be want you want to exclude then.

A primary residence usually falls under the 121 Exclusion which allows you to exclude from gross income up to 250k in capital gains (for one taxpayer) and 500k for a married couple.

Currently if you live in a property as your primary residence for 2 out of the past 5 years you can qualify to exclude up to 500,000 in gain from the sale of that personal residence.

I would support this, I use RS Means as a resource for my government bids, they are used by government contracted architects, they exclude indirect costs though (sales tax on materials, work comp, overhead, etc), that means, they are basing it on DIR labor rates and wholesale material prices.

It explicitly excludes W/D's in communal areas (ie: a laundry area shared by all the tenants). 

If you are going through your brokerage, then they will probably lend 50% of the current stock value (some securities, such as penny stocks excluded) through a margin account.

@Bill Coleman I specialize in insuring these operations at a commercial level in Washington, so I can speak a little to the insurance piece.Illegal activities are specifically excluded on standard property insurance policies, and if the growing operation is the cause of loss - like an electrical overload causing a fire - the insurance company has a legitimate reason to deny the claim.  

Racing and stunt driving/riding are excluded on auto policies.
