So, first I'd encourage you,even though technically  you might not need a QI for a simultaneous swap. 

Technically, you can do this same thing with any HELOC that you might want to open, both in the 1st and or the 2nd mortgage position.

A clean background is important.

If there are more people living there, Make them do applications with background checks and add them to the lease for responsible parties. 4.

A large background in a subdivision located in a cul-de-sac.

For example, I mention that every adult must pay a $30 application fee, pass my credit/criminal background, make a combined income of 3x the rent, and whether or not the property accepts pets.

But as I have said before your  sand box is pretty cool and very hard to duplicate in most of the US.. but then again you play the hand your dealt and the money is made in real estate when you understand the very technical type transactions.. where the mass's just think of vanilla sales .. 

Commercial brokers will know more becasue they have to... they get the contract and hand it off and the deals i have done there i get inspection addendum's written by the attorneys and boy that is very dysfunctional.. no explanations as they are getting flat fee's and spend zero time doing what needs to be done to keep transactions together the little things the public does not see. but anyway thought provoking.... 100.00 and hour is a pittance to a seasoned agent.. don't see that flying.. but to a mid level or starter who comes from a back ground of getting paid by the hour..

A professional is someone that conforms to technical and/or ethical standards of a profession.

Tour the property, show them the property, explain to them that the minimum requires are verfied with a background check and income verification that they pay for.
