How and when you should start to liquidate your portfolio?

The nephew said "It's a pretty cool place, I like it". 

Cool.

I don't know, lately I've been thinking if I would still want to be doing this whole landlord thing in the future and therefore trying to figure out if there was an tax convenient way of liquidating all rental properties and live off a brokerage portfolio.

It seems like a really cool opportunity, so we'd love to participate.

With $7-10m in liquidity, compound interest is all you need to play it safe and do well.

If it checks the box of affordability and is a cool place to live and put down roots, that's where you should buy property. 

I will say that the returns are a lot better and it is nice that the money is liquid in case I have do have some major expense like a roof or AC pop up.

Cool thanks for the info!

Your maximum allowable purchasing power is going to be entirely dependent upon your experience, liquidity, and leverage you can get - which will be deal specific and investor specific.
