Thank you this are incredibly insightful questions that I’d never thought of!If you do go down this route and it seems to make some sense to me.
You will do so with assumptions on cost. If buying an apartment those assumptions can prove quite conservative if you dont check for the following.
Is fire cert in order?
Is the roof in good order
Is the sinking fund in a healthy state.
What is ratio of owner occupier to rental. High owner occupier is a good sign.
Had an apartment with fire cert issues that cost me many thousands to rectify
Much appreciated!
