I have had to answer the infamous late night roof leaking phone calls, and dealt with: leaking toilets, leaking water mains, faulty electrical panels, broken water heaters, broken furnaces, underground oil tanks, troublesome septic systems, late rents, tenants dog eating the walls, unresponsive tenants and every other real or imagined rental horror story that people who are either too afraid or unwilling to, use as an excuse not to invest.

Instead of flailing with all that, I'll get good at finding deals and/or raising capital (or both), so I can add value to them, also.OK now, sure, I can still deal with proven contractors for small jobs, floors, electrical panel, roof repair, painting or whatnot -- I kinda grimace and get through that, for a buy & hold that is almost rent ready, but that's about it. 

I sold solar panels door-to-door.

Before shot of the back of the extension with some wood panelling from the top floor.

That means architectural and structural "as-built" drawings, a 8-12 week wait for permits before starting work (and that's a minimum, longer if you have plan revisions), separate heat source for the basement unit, separate electrical panel for the basement unit, and a handful of other odds and ends. 

A lot of the 2-4 unit properties in Cicero are due for a service upgrade, new panels and many of them also are full of cloth wiring that needs to be removed.

The microwave could be run off a solar generator. 

The last 10 years of my life have been devoted to developing utility scale solar projects which deal heavily in taxation issues such as investment tax credits, bonus and MACRS depreciation schedules. 

We (my company/companies) use Huawei inverters in our commercial utility connected solar farms and have invested small 6 figures (8 figure if you include the cents;) in their products.
