Your energy will take you far in this business.

Stick to it.Real estate investing is tough and those who say it isn't tough either have never bought a property or are trying to justify how much time, money and energy they’ve spent to get the meager success they have.

Read the 2 complaints on the Better Business Bureau and all the one-star reviews on google (all have same detailed complaints).

They also usually are more energy efficient as the water is heated as needed and not heated to store in a tank that might not be used for many hours and tanked heaters typically have heated more water than needed (and this is desired because running out of hot water is a bummer).I do not want an annual maintenance effort as large as descaling a tankless water heater at my rentals.  

As a Turnkey Brokerage ( and I have done business with everyone of them that are in the market these days and in the past) Zach gives 5 star service.Keep in mind though this is real estate so you must do your own due diligence etc. 

We've never had a rental property before, but we are handy and I do have some time/energy to put into such a thing.We have a house in the Boston metro area that's worth around $900k.

There's nothing wrong with doing virtual walkthroughs in my opinion IF you already have a relationship built with that broker AND you have a good idea of what you're doing.From a broker's perspective, if I'm spending my time, energy, gas, resources, network, analysis, etc. on a client that is either not making serious offers and/or is spending more quantity vs. quality - then I may be averse to walking every single property.
