South of DFW rookie with a question on new builds.

[Ricky Roman]

Hello BP peeps. Very new to REI just reading and studying various topics/discussions/podcasts. Still going back and forth with renting or flipping... One topic I haven't found yet, is when it comes to a rehab, at what point does a demo and new build become more cost affective? I'm trying to gauge whether buying a home that needs extensive rehab would be best to demo and start new for renting out or flipping. Thoughts?
