Several questions come to mind are:1. usually with solar, PG&E sends an annual bill based on difference between electricity produced vs consumed for the year.

I am curious what platforms other landlords are using to collect rent?

But also because It isn't a typical 30 year fixed consumer mortgage loan, I have very very low closing costs.  

So he's got some wiggle room and probably has some consumer debt.If he's buying a cashflow positive investment property, he should be OK even just using his base salary and ignoring the auto repair business...

Laborious and time consuming. 

If the local utility supports Net Metering aggregation then you can essentially "assign" how much production from a single PV system goes to each unit, then with the right platform/systems in place you could bill tenants based on their individual allocated production (I happen to be in this type of multifamily solar niche). 

It's also an open platform for them to tell us anything else that may need to get fixed.   

Most big companies on their consumer website have a link at the bottom for corporate website.

Any ideas on tasks like...Finding tenants- This seems to be the biggest time consumer and toughest to outsource.

It was very simple, just time consuming because you can't skip ahead or "beat" the timer.
