Always good to know who’s actually in the field.

Are you just relying on your brokerage's forms software, using templates/macros, or has anyone found a good way to automate the repetitive parts so you're mostly reviewing instead of filling every field by hand?

I never considered scaling until 4 years ago, then heard all the talk about cash flow and having a large portfolio, and the "real estate is road to the financial freedom" in this current market not 2010 (that's the worst one and numerous gurus prey on people who don't even have the capital to invest).

Quote from @Bryce Jamison: @David Greene talked about this recently on his new podcast.He recommends being an overall real estate professional so you can make money in numerous ways and in different economic climates, and more importantly, you can help folks in all stages of their life and with all their real estate needs.Sometimes your helping folks find a good handyman, sometimes you're renting them one of your units only to be their agent later on when they're ready to buy, then maybe you're giving them house hacking tips after they buy.I can’t disagree with that, although in this age of almost unlimited information, I believe in the need to specialize.
