What type of loans are appropriate for business owners and self-employed individuals to scale past 10+ properties? 

You could always invest in funds like https://fundrise.com/ (allows you to invest in RE without being accredited) or https://percent.com/ (allows you to be a private money lender without all of the work) if you have money and less time. 

Hi,It seems this is hotly debated on the internet.If I have a single family home and rent rooms out, are proportions of common areas allowable in calculation of depreciation and expenses?

If B, then make sure that you are heavily insured because you are acting as a GC.Also most states (like Arizona) will not allow a homeowner to act as Owner/Builder on a property that they are planning on renting, only their own personal residence.

I’m not aware of any state that allows what would be a junior lien and would be extinguished in the foreclosure sale to game the system and record the lien in the gap between notice of the sale and the actual sale.There are ways to legally address such “liens” when they do arise in the middle of a foreclosure… such as redemption or surplus or even a QT action.

If 3 unrelated tenants are allowed in 1 bedroom.
