To be "hole poor" is then to have a hole you can't afford. We are approaching this stage: we have the precursor to the final hole (similar to a Nydus Network).
So far we have purchased an old duplex (seen here), knocked it down (seen here), and are now in the pre-hole stages (seen above, more pictures here).
As soon as a full hole is dug we will have achieved hole-poor! Lol.
