Btw, after 40+ years as a real estate investor, having seen many, many investors both succeed and fail, I can tell you that a strategy that relies on taking advantage of the lack of knowledge of the unsophisticated segment of the home owner population is NOT sustainable.

While I agree it varies per segment...inventory is up across the board.

@Dave Meyer your survey won't work for people with portfolio balanced between different segments / types as each has it's own concerns / strategy.

Realizing I didn't know anything about this segment of investing, I picked up a couple books (including Brandon's "The Book on Rental Property Investing") and have been listening through the Bigger Pockets podcasts from the beginning over the past few weeks.

For example, there are three major tenant pool segments in Las Vegas.

And if you service an area "in need" not only does the government look at that favorable (they are the ones that run compliance, etc.) but sometimes those segments are "growing" segments.

Wholesalers who are annoying you are doing so, because that behavior is incentivized and rewarded when they find the right market segment. 

As I'm doing my bookkeeping, how should I go about segmenting part of these utilities to the AirBnb business and part of them to my personal finances?

Each segment has different characteristics.
