Answer:
$ 300 but the home owner will keep the leaf blower.
Step-by-step explanation:
If the neighbor is successful in the conversion action, FMV of the leaf blower converted will be the measure of the damages done by the homeowner. The damage value or the FMV is computed or considered as of the place of the conversion and the time.
In this case, the leaf blower when the homeowner damaged it have the value of $300 at that time. So that is the amount i.e. $ 300, the neighbor is entitled to, but at the same time, the homeowner gets the leaf blower after paying the $ 300 to the neighbor.
