Enemy method. 

You will constantly hear of shortcuts during construction and the conscientious decision to use lower quality materials during the renovation.

I get more responses from FB marketplace but the quality of the responses from Zillow rental manager is stronger (judged by who views the property).how many people have responded to the ads listing it for rent?  

Quote from @David Ramirez: Call remodeled comps in the area that has been bought and sold within a year Especially for this method, you can paste the addresses in propwire and look in the chain of title to see the last owner before it was sold after being fixed up.

From what I've seen through pictures, the quality is sub-par (e.g. bad patching, no primer used, no corner bead used, etc.).I have recently started to get more strict on timelines (this is now 2mo delayed), and now he is halting the work.

How do property management companies perceive these areas in terms of tenant quality and rental stability?

But hey its money whether its a living is another matter For the future I am switching to the buy it off the market and put it on the MLS with a realtor method.

I would consider doing vanilla long-term rentals, but I think I want to do the BRRRR method, as scaling will be a challenge for me without it, I feel.

If you need any help with the flips or man power i can definitely provide a high quality service 

Smaller properties are cheaper to update or can use higher quality materials.
