Can they prove how long it takes to rent a vacant property?

BRRRR is still doable but is very, very tough right now.

If your tenants aren't looped in early, it could make access for inspections tough.

And doing 3-4 units FHA is tough unless you have a huge down payment. 

@Trevor McCormick I would say that it is an okay market but is very saturated and alot of investors are having a tough time right now.

Being a realtor is tough, and there are quite a lot of unserious buyers that are just poking around.

From what I have tried to read from a non partisan site (tough to find nowadays) I believe the issue has been insurance companies lost billions in the past five years and the past 5-10 years have had the most costly fires ever.

As a few have mentioned, the best way would be to call the listing agents directly, but depending on how much time you want to dedicate, setting and going on multiple appointments with different people could prove to be time-consuming. 

I may someday, want to learn how to make banana splits.Run with what you've got, prove yourself first (you ain't done nothin' yet!)
