The arlo is good enough for sustained activity but my nest wifi cameras give us more real time but require internet. 

I'm quite a few years away currently but wouldn't mind a couple nest eggs.

I'll have a larger nest egg.

Go make more money first and move out of the nest young buck.

I have a sizable nest egg at this point and can easily put down 10-20 percent on a great multi-family in New Haven but are my aspirations to get in the game as soon as possible damaging my potential to be successful in the DC market, too?

Maybe some day, but for now you would probably need separate services for most systems (Nest thermostat for remotely controlling HVAC, sperate system for pool, etc.)You can of course have some systems bundled together if they are the same brand.

If you plan and finance correctly, you may buy 2 or 3 investment properties with the nest egg that you have. 

Once proven, you can always refinance out and capture 75% of the equity.I figure the risk is diminished slightly since you will be using anywhere from 10%-20% of your cash position and not dumping the whole nest egg in.

Also installed a Google nest so the client's can't turn the air too low.My question is what can I do with the contractor that installed the unit?

You need to throw them all out of the nest and teach them to fly.
