Where do you find that residential rent is highest unreported income? Last figure from IRS I see is 2014-2016 and rent was a quarter the size of non-farm proprietor: https://www.irs.gov/pub/irs-pdf/p1415.pdf#page23 https://www.irs.gov/pub/irs-pdf/p1415.pdf#page23 What percentage of total rents are unreported? One would expect that the majority of rents are collected by professional management companies subject to reporting requirements that make underreporting unfeasible. Maybe that is an incorrect baseline? What makes you think that rents are already as high as the market will bear? After all, rents keep rising, right?
