Buying rental w/ solar panels -need to take over payment plan

[Luciano Suehara]

Hi, I found a good investment property but seller is asking to take over the current financing plan for the solar panels (124$/mon for 25years - already paid 2 years).

I'm still researching the pros and cons and wonder if anyone had this situation. Some many questions like:

1) How to charge the tenant on electrical bills?  

2) Does it appreciate or deppreciate home value? 

3) Insurance costs? I'm guessing premium will be higher in case of roof or panel replacement

Im not against them but just want to analyze all pros and cons.

All input is appreciated! Thanks
