If you are thinking about energy saving upgrades like new windows or upgrades to heating or cooling you can save a lot of money by working with their programs.- Think about the wiring.

It’s sounds like you have a lot of good energy. 

I just put cheap bulbs in and let the tenant put energy efficient ones if they want. 

Even if you engage a broker, you should still shop around an additional couple lenders yourself (if you have the time/energy).Freddie SBL loans cap at 50 units, so you won't be able to take advantage of that program (unless they can somehow make an exception), but there are still great Agency (Fannie/Freddie) programs that would work. 

It’s a complete waste a time, money, and energy if you don’t talk with them.Don’t over think this.

Their energy is spent trying to work something with them (a bird in the hand is worth 2 in the bush).

There’s a cost to working a 9-5 that is taking away from doing something that can eventually make you a lot more money and more importantly not drain your energy.

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.
