I am trying to figure out how the agent gained entry to a house not listed for sale and owned by someone else.  

Its a great site to meet people and gain great knowledge.  

Many couples  want to use the 5 year period post divorce for real property transactions that can still benefit from the section 121 marital exclusion on capital gains. 

Fees mount up, and you, hopefully have gained a good investor/friend.

The capital gains tax rate on the sale of personal property you held less than one year is the same as your marginal income tax bracket rate.

Here I am; I've had rentals in the past and didn't know what I was doing and ended up selling the properties....mistake.I'm here to learn as much as I can so I'm not making mistakes, you'll see me in webinars, on the forums asking questions and overall trying to gain the knowledge necessary to not loose money in real estate investing. 

You can gain experience in chatting with potential sellers - no one is born with this skill, it is manufactured by you.

It takes me about 3 hours to do the work, and the reason I have the time to do it is because I don't participate in the world of gainful employment, which is more commonly known as Job. 

I'm happy to be here and looking forward to gaining knowledge.

Welcome Robert.My suggestion would be to partner with a more experienced investor to gain experience and contacts, before trying it by yourself.
