The hubs and I are in contract on our first sfh investment home in SE Portland.

If you are looking to invest in the UK then you might want to join the Property hub as well. http://thepropertyhub.netBest of luck.

My hubs and I have a couple rentals we are renovating and hoping to build a guest house (to rent out, of course) or buy some additional rentals soon.  

We currently have Z-wave locks that we program via a wink hub.  

As @Charles Maxwell said above- There are a lot of ways to make money in property.You might want to take a look at the Property Hub - (which is an attempt at a UK version of BP).

oh, it's called Hub City REIA

Currently the system is setup with a series of sensors that communicate with a hub via ZigBee wireless language.

They have hubs across the united states with the main hub and world headquarters based in Memphis.  

This was my idea: Using my house as like a central hub and then branching out by saving enough to put 20% down on duplexes and Triplexes after I have cleared my debts and increased my credit.

If you can get ahead of the pending transit hubs and are OK with a little risk for a little reward, so are places in the East Bay.The Bay Area crew is super helpful and friendly, don't hesitate to reach out to anyone.
