I recently considered switching to KeyCheck but decided to stick with RR for two important reasons: 1) RR allows for weekly rent collection, which is recommended by my real estate attorney, and 2) RR has lower credit card processing fees for tenants.

I wouldn't go for a condo, as the HOA fees and restrictions could affect your ability to rent it out, and the resale value will always be lower than a comparable SFR.

House A has a lower (but still high) wind storm deductible at 1%, while house B has a 5% deductible, and no one is occupying it as it was just closed.

So if you are currently in the 37% tax bracket then you could take advantage of deferred taxes + a lower tax bracket.

The only way to modify a loan to a lower payment during a time of rising rates is to move a bunch of principal to the back of the loan.

Are you seeing any lower rents?

As Stuart mentioned, it gets even tougher with lower price point homes.

Basically, there's no free lunch when it comes to taxes.Depreciating property lowers your tax basis.

This could lower your resale value. 

These figures suggest the property may be overpriced based on current rents, so negotiating a lower price and increasing rents could improve the deal.
