Is how much time you have available right now to commit to the business. If you don’t have much, it doesn’t mean that you shouldn’t give it a go, just be more realistic about what is possible. So, for instance, it might not be sensible to take on a renovation project that requires your time and commitment if you are coming up to a busy season at work. You shouldn’t underestimate the time needed to view properties, organise funding, find tenants, manage your properties, or simply to deal with general admin and paperwork. Which is why, ideally, it’s good to have others on board who you can rely on to help out, particularly if you’re still in paid employment elsewhere.
