What are some great RE software and information based sources

[Garrath Robinson]

I am a new investor and will be starting out using the BRRRR strategy.

I was hoping to get some answers on some great RE resource websites as well as software you all use.

I've done research on a few, just would like to hear some opinions from people using them daily. I know many resources are paid-for, so I would like to get a better idea of the benefits of certain sites before shelling out the dinero.

Thanks!
