you report "Man, I gotta go check out this neighborhood for a possible house sale, but I'd love to have some company - come with me!". 

Some of the 1 ton units will plug right into a wall socket but normally you power them from the outside unit.

keep the water and power cost on the tenant. 

Won't the bank simply sell these listings as REO sales in their time?

That doesn't count (and I had to sign something that I would never reveal how much money I walked away with).2) I use to be the king of the short sales in 2009 until they passed some laws that basically made going after pre-foreclosures very risky.

I want to list my multi family property for sale but I don't really want my tenants to know I'm selling it.

Be happy with the niche you select and know the market well too, especially the best locations.Always remember to do a math analysis and try to look at all prospective properties before you make an offer or at least have a clause in the sales contract that gives you some time (about 10 days) to make a detailed inspection and possibly back out of the deal without much of a penalty that will hurt you too much.  

It will not increase the sales price by 15k.

I am needing to know that if I get a seller to agree to terms (owner financing) using a purchase and sale agreement, then assign that contract to a tenant buyer with my assignment fee, do I need to be licensed as an agent/broker?

Is it even for sale?
