Southwest, Midwest, Southeast are typically where properties will allow easiest entry as you detailed.

It's one of the easiest ways to get right into the game and have a relatively easy win.I don't know if I'm the lone wolf on this, but I'd steer clear of flipping or going BRRR.

Easiest closing I have had by far, he wanted a Tax return for the schedule E, Rent Roll, and personal balance sheet. 

The easiest route to legal may be to convert the unpermitted unit to an ADU. 

I have looked at the Home Possible loan that allows a “gifted” down payment.

@Jack McWatters From what I've seen, the easiest to convert to apartments are extended stay hotels/motels that already have a small kitchen + a bedroom that's actually walled off and separated. 

What is the easiest way to find out someone is a private lender and how would I go about convincing them to fund my deals?

This makes the best and easiest soup in the world.Key is to set the budget so you know where your biggest costs are.
