I understand from the podcast and reading how important it is to account and save for Vacancy, Repairs, and CapEx Expenditures in Buy and Hold Rentals.

Your buyer should be prepared to make major capital expenditures should a new roof or similar be required, since there are no funds in reserve. 

The P&L for 2016 shows maintenance expenditure was 11% and NOI was about $45K.

Have you included: Vacancy allowance; Maintenance costs; Capital expenditures; and Property Management costs, somewhere?

Or just save ALL your so-called Cash flow on the single family rental and expect to spend it on the Capital Expenditures that WILL come up.  

For capital expenditures (big ticket items like the furnace/roof failing)?

With MF - things tend to happen all at once - all two or three water heaters are the same age , etc. so be prepared for that by making sure your not buying someone else's headache and start putting money aside for capital expenditures like that.

Many do not include ongoing maintenance and capital expenditures in their calculations.

Most significantly, the idea that a building grossing $80k a year is only reserving $200 a year for cap expenditures is absurd. $10,000 is a better guess. $160 for vacancy reserve is also ridiculous.
