Your job as an investor is to get the best deal possible on a property so to say you owe them some kind of favor of loyalty is laughable imho

Favorable taxes and sunshine! 

If you want it to be an investment, you may not qualify for favorable second-home financing.

I wonder if Banks look at it differently- more favorable?

On top of that real estate has historically been highly tax favored with mortgage interest deduction etc.

You are setting yourself up to ruin a good relationship to try to curry favor with a new one, but REO listing agents are not going to be showing you properties.

As others have said moving into the new property can work to get more favorable financing and BRR can work as well as long as everything goes right. 

What's really wild is their acquisition philosophy overall, as described on page 8: "We intend to continue to expand our scale of operations and develop properties and make acquisitions even if the rental and housing markets are not as favorable as they were when we commenced operations, which could adversely impact anticipated yields."

Like with any other type of asset, a down market may come unexpectedly, leading to less than favorable outcomes for investors.

The established areas will likely be fine but everything in between will probably lose favorability to the suburbs where people will value more space (and perhaps timeliness of trash pickup).I hate to say it but from my viewpoint (which is admittedly much less informed than other users on this site) the outlook is grim for the future.
