Are you talking about permanent movers, or those on vacations of some sort, or people who are temporarily to be housed due to an emergency and then intend to move back to their old stomping grounds?

Please let me know which island and what trades you need and I may be able to provide you with some referrals. 

I wouldn’t trade what we’re building here for anything in the world!

Show them you are interested in any and all houses (not just theirs) and that they need to expect a trade-off.

What I'm seeing some folks do is trade equity to assume mortgage, especially in nicer places that got low mortgages.

It saves all the trades time!

Properties can’t be continuously valued so you have a really hard time providing transparency and avoiding insider trading.

As well as having enough cash reserves to handle the repairs that will come up on an emergency basis , such as a new roof, or a new furnace in February . 

Every time a building trades in Berwyn, there is a new compliance inspection done.

A couple things you have to consider with rental arbitrage is that anything that breaks in the house is an emergency for you, but not your landlord.
