How safe is this investment?

Zero risk of capital loss because the investment takes place within your property.
In the worst case, you will get a home that adds revenue instead of adding costs.

Return on Investment (ROI)

A performance measure used to evaluate the efficiency of an investment or to compare the efficiency of a number of different investments. ROI measures the amount of return on an investment relative to the investment’s cost. To calculate ROI, the benefit (or return) of an investment is divided by the cost of the investment, and the result is expressed as a percentage or a ratio.

(ROI = Gain from an investment-Cost of investment/Cost of investment)
