So my question is how can/should LPs verify the lip service GPs give on their experience and handling of this space?

BUT always trust and verify. 

@Kevin Collins I apologize; my response came out a little rough around the edges and I assume that you certainly have done your homework prior too.... but that is a bit of my point... nothing will change when you go and work with a realtor and find investment properties yourself... figuring out what the property is worth IS PART OF THE ANALYSIS (if that's important to you) and because of this it is no different than other than you should now be verifying what the realtor will tell you it's worth as opposed to what the turnkey is telling you. 

You just need to verify that.

You can still qualify so long as you have verifiable income.

I obviously have no way of verifying whether you own the asset or not, but find it odd that you'd throw away years of attempts at building your reputation and leave BiggerPockets rather than simply shut Melanie up by stating that you own the thing.
