Hello!
I would always recommend you to give it a shot and then post it here, this would help you the most.
This is a very typical market sizing case, where the key steps are:
- Calculate the total population
- Calculate # people in a household (~3) and # of houses owned per household
- Calculate the # of transations per year
- Estimate growth
Calculate the % of the total adressable market that any firm in particular could have -in case it´s asked only-.
Hope it helps!
Cheers,
Clara
