You’ve got 100K of equity in the Portland property. You should be able to get a line of credit or redraw on that. If not the banks will throw a personal loan at just about anyone these days. Get the $5000 to finish the job and get it tenanted.

Once you’ve increased your cashflow you need to steady your position and consolidate.

To be honest, selling the Portland property would give you 100K profit. This could be used to give you a buffer on your home loan and kick off three to four new reno projects in the same area. This would give you a much more stable platform.
