Any Problems with Utilities Included, as Solar covers Rent

[William Wiggins]

I built a new all-electric house a year ago to minimize its use of electricity. After reviewing the renters' year-long electric bill, I've confirmed that the house is more efficient and solar can cover nearly 80% of the house's electricity usage. With the electric bill included in the rent, it is very possible to generate another 8% more in monthly income with the outlay of around $24000 (net $17,000 actual cost), netting me a consistent 8% per year ROI with minimum risk. Future tenants to be charged the local electricity rate for their usage and given the monthly target that previous users met with an additional 5% grace. Are there anything issues or concerns I'm missing?
