You can install Nest thermostat and lock tenants from accessing, but they will still complain. 

By the time the birds leave the nest you will have more equity, more leverage and more money with 4 doors than you would ever have with one. 

He claims he doesn't have 10,000 to invest in a 200k condo downpayment (me providing the other 10k with a FHA loan) because 1 million dollars isn't enough of a nest egg to loan out 10k. 

If I want to "sell" a property, I've got to manually update things and a lot of the nested IF statements are a pain, etc.  

The point I was trying to make was that unless you already have a substantial nest egg, then you're just constantly losing and spending money and lenders won't like that

I have one parent who has retired and the other a few years away and are quickly finding out the "nest egg" isn't going to be nearly enough during their golden years. 

However, this would require her to hand over her nest egg, all of her cash and some of her 401K to purchase the house. 

@Lucas Roswell - I've used Nest before - good to hear honeywell is another good choice.

I'm going to add the new Nest thermostat devices as I retrofit one of my buildings for central HVAC.

You’ve worked hard to save, budget, and build a little nest egg, and you’re just looking for somewhere to park it for a few years with the possibility of earning some interest.
