Marriage is like playing Russian roulette with 4 out of 5 bullets in the chamber nowadays.

We both work way too hard, playing tag team in the afternoons with our boys and finally, after bedtime, if we’ve got the energy, we’ll say hey, eat a dangerously late dinner and then fall into bed.

To install solar panels and a geothermal heat pump in the Boston area might cost about $100K retail, which seems like a non-starter UNLESS incorporating these into a mortgage made financial sense for the buyer, and...appraisers factored this into the appraisal valueSo in other words, if the additional amount on a 30 year mortgage were offset by energy savings & programs, AND the buyer was able to live carbon-free, it seems that this might attract a savvy and enlightened buyer.

@Arlan Potter thank you so much for the advice, that is great to know as I am thinking to start small as well, and learn as I go then do bigger projects, rental properties are in my plan but a little further in the future, as I would like to use my energy for the time being since I have it.

I then found EnergyFunders, which seems to be the biggest name in the energy crowdfunding space, as far as I can tell.

It has the day's date and then bullet points underneath it.

@Peter Padalino - couple suggestions, as I've been in your shoes.  1) Go crazy on energy efficient items - all LED bulbs, NEST or EcoBee thermostat, etc, etc.  2) Get someone to quote solar power for the roof if you have APS - I went solar and LOVE IT for rentals. 

I've known individuals that had the capital but just didn't have the energy to get into any other investments...BE THE SOLUTION, create your own opportunity. 

Focus on making the unit bullet proof.

Then he has to decide if he wants to figure it all out himself, find a team (agent, contractor, PM) and manage them from afar (which means lots of time and energy but maybe better returns) or would he rather pay someone to handle it for him so it's just about passive income building with very little hands-on work (turnkey).Living off the income from $140k isn't going to happen, but it's a great start in the right direction.Best of luck (to your friend ;) !
