As far as talking to multiple realtors, loyalty is a two way street (talk to as many as you want but they'll be more likely to send their best deals and give better service to someone they have an exclusive relationship with). 

Why give up the cashflow of a $10 million asset when between depreciation and appreciation you'll be taxed $3 million on 7.5 for example and be left with cashflow on a $7 million asset.Also remember that the $500k exclusion is unlikely to be indexed to inflation.

Maybe I should rephrase...I mean the principal broker is listed as an exclusive broker on the listing..Does that mean he is also paid as a broker, in addition to being the "house"?

Basically I was given exclusive for my company to lease out different office/retail spaces.

If a property is listed on the MLS, the listing agent has the exclusive right to market the property.

These are all goals, and not exclusive. 

This is from the CAR website:A reminder that the Chicago Residential Lease, and all of CAR’s forms and contracts, are an exclusive member benefit for use only by Chicago Association of REALTORS® members or those who are party to a transaction facilitated by a Chicago Association of REALTORS® member.

But I know a phone sales type that almost exclusively cold calls and sold 19 properties his first year.  

I had similar questions/discussions with my accountant this year regarding a business my wife started and it turned out that since we weren't using the space in our home exclusively for her business, then we couldn't write it off.

We've got great reviews on VRBO so I don't think we need to exclusively focus there and I'd like to be able to hopefully capture more potential renters by also listing on airbnb.
