Systems, Automation & Scaling: Also, I have watched / heard the LO gurus talking about 'automating' and 'outsourcing' practically everything... from buying leads and using foreign and domestic VAs that generate and / or 'pre-qualify' people, to even doing their follow- ups and booking appointments for the deal maker... to 'systematizing' practically everything else, under the sun.

I know  I have lots  to learn but  not going  to sit  and just  watch   I'm  ready to  "Jump in the Note Investing business"   Would  love  to hear  how  someone  did  just  that. 

I also watched and listened a guy on YouTube named Grant Cardone who now owns about 4,000 units that are rentals.He tends to act rather forcefull but has interesting thoughts about staying away from single family rentals and personally owning and financing anything because they typically create liabilities for you personally and tie you down.  

@David Rutledge - I feel like I'm beating a dead horse a bit, but I do have one new bit to add.  

I watched a video from the Quick Water Heater Company who has some informative videos https://www.youtube.com/watch?

My dad was a big tax sale buyer in the early 60's I learned it from him.. watched many an investor just throw money away over the years..

You have to watch an area over a period of time to know what the going rents are. 3) taxes are on the county assessor web site but know if the valuation is well below the purchase price you will see a sharp increase a year or so after you buy when the county adjusts the valuation.

Watch out for unpermitted additions!

The fastest ways to attract new investors is by giving them what they want (home buyers and properties) and target them through Facebook advertising, Craigslist, BiggerPockets, etc.Let me know, if you want to watch a video I made with more details on how to target the right people and what type of offers to put in front of them.I also can do it for you for a trial period, if you're too busy or don't know how to do it.

Certainly, Class A is what can get overbuilt / over supplied over time and hence, those folks playing in that space need to watch metrics more closely that impact new constructions like absorption rates.
