Is there any sort of capital gains exclusion for that?

Yes I have an agent to call "buyer agent", but not yet officially, i.e have not signed the "exclusive right to represent" agreement nor the consent of dual agency.

They advertise on FB and craigslist as well as newspapers just like us common folk.Now they play contractor.

Hey Benjamin, To find prospects you could also check the newspaper.

@Saman JafariOn a conventional loan, this is called a delayed financing exclusion to the seasoning requirements.Yes you can absolutely buy cash and then immediately (or as late as six months later) refinance the property pulling out up to whatever LTV requirements you could have gotten if purchasing with the loan in the first place.

Coordination is much simpler when it's within the same firm.To illustrate, my small firm works exclusively with US REI investors.

Newspapers, internet searches and motivated seller websites list leads for tax liens, divorces, and bankruptcy.

@David Caradonna to recap and confirm understanding; - You don't want to sell any of the properties, at all- Don't want to touch the existing mortgages because there sitting at great rates- Only and exclusively want to tap equity to re-deploy to grow portfolio. 

If i have a cash buyer that exclusively prefers to work with me and remain anonymous for the most part, but i find a contract assignment for sale..

As community property. her exclusive ownership automatically survives.
