At least half of the videos are probably abject garbage or gurus selling a program.

I have programs that require only 10% down for the purchase, and will finance 100% of the rehab.

Or only to properties being managed in an external Property Management function?

Make sure you have smoke and CO detectors in appropriate places, GFCI outlets near water, functioning mechanicals, make sure everything is in good condition and you shouldn't have a problem.

There are different programs for 1-4 units, 5-8 units, and so on.

Some rehab lenders have favorable refinancing programs to convert the rehab loan to permanent 30 year financing.

Six weeks into their program, I earned just over $50K.

There are a few programs that can do second position financing but typically underwritten based on your personal income.
