If you need the cash flow, the longer term will save more money per month for your wallet.

You can buy one at most hardware places for fairly cheap.

They hype it up so much and the people at the back of the room likely silently judged me and others made for the exit with our wallets intact.

Do not BUY a system from a "guru", work with the local wholesalers, ask people on BP, go to the REIA (leave your wallet at home) and meet other wholesalers, network, network, network NOW.

If you take the right steps to insulate your real estate investment and remember to unplug your appliances when they aren’t being used, you can keep your wallet stuffed and your property value high.

I would paint the cabinets, put new hardware on the cabinets, install a new countertop/backsplash.

Accreditation really just means you've got a fat red target on your wallet..   

The PV company advocates for wiring all the PV panels in series and then letting any excess electricity from the panels balance equally through all three meters - that's technically the most cost effective for the whole property, but would mean I need to install a bunch of extra hardware to measure actual electricity usage.
