We are talking with a couple of clients about doing build to rent for them right now.

Indian RE has been on a tear.

This might turn out to be a good approach.   

Looking to get into flipping projects preferably in the western suburbs

Co-hosting is just like any other business---- scalable systems. 1) Know how to build systems2) Find a mentor who will teach you3) join a mastermind that will teach you4) Learn and grow as you go... but have insurance.

I'm no expert, but I know several people who have had loans called due on sub to deals because of the way they structured their insuance policy.

I'm keen to learn sub-to - other than Pace, are there other masterminds or options that I might use for some mentroship/education?

If so, maybe you just keep it and do a cash out refi once rates come down a little more.

I have another rental property that has suspended Passive Activity loss (that I decided to hold), can I use one property PAL to offset gain on sale for another? 

This would be like thinking pizza.com has the best pizza.
