I need to source the data myself, run the numbers, check the calculations, eventually build my own custom spreadsheet etc. 

Having a main water source available is pretty important and not having it could affect your reviews.

With time management, sourcing materials and learning how to complete task on your own.

Acquisition is the root of real estate investing - if you can master the systems and processes around that you will have a skill that can be translated to bigger and bigger deals.I'd advise against developing on your own at first - if you find a partner that is knowledgable then go for it.Syndications can be great, they also can be horrible.

Echo this and add other sources like Zillow or Houzz...really great to get ideas, for free!

I’m particularly curious about:Financing Options: What types of loans or funding sources work best when scaling quickly?

This is what active renters look at too which is why I believe it tells a better story of what rents are currently at compared to other sources. 

Hey Mark,I’d also recommend considering DataFlik for deal sourcing and lead generation.

Zillow is still a great source.

Making real estate your primary income source isn't passive unless you have access to significant capital.
