Finally decided to renovate or knock down/build our investment free standing house next door.We rent it out for $900, and believe that we could rent ours out for around $2000, we could move into the new build, so the extra interest for the build should be a no brainer? Today we did a bit of research and viewed some narrow block houses. Quite impressed, around $400000 for double story with impressive stuff. After doing the research, as you do, we find that the builder has a poor track record and we have been scared off!! Now we will continue looking for decent project builder, or perhaps go the architect/ builder route with good recommendations around $1400 psm. Has anyone got some ideas on way to go? Should we reno old house, put another floor, or spend around $400000 for a new project home? Much appreciated!
