As long as you take into consideration the possibility of a slightly longer vacancy factor in your calculations I think you should be fine.

Are they doing everything possible to expose properties to the broadest possible market?

while it’s always possible to structure scenarios where you are both a broker and a principal, the APPEARANCE can be one of impropriety.  

I’m not new to Zillow, I’ve sold many properties there FSBO but this is a new one: Buyer appears to be a land speculator, I docu-signed a contract to sell a vacant lot and thought nothing about them asking for a 14-da...

Some people want to grow as much as possible and maximize all the opportunities while others are fine with a few deals.Remember all you know is what you know but Its what you don’t know that makes the biggest the difference. 

Sure, it's possible.

I do know of a few that could help, just sent a DM.Also 100% agree with @Bill J Fay, being up front about costs and region will help as much as possible going into a tricky deal to try to lessen any potential 'surprises'.

I'm not saying it's not possible - but it ought to be worth it.

First, get as organized as possible and present yourself as a business, even if it's just you running a business.

Rookie here,I'm possibly looking into the BRRRR method on an SFH or duplex.
