The lesson learned is vetting the potential buyers before pulling the trigger on the one that might look the best on the surface.

As such, the only "deals" typically require extensive renovation, because anything that is purely surface level retail buyers will likely outbid you.  

Most mold is on the surface and can easily be removed with a bleach solution or one of the many mold treatment products available.

It barely scratches the surface. 

On the surface, this sounds like a sketchy idea.

If you'd be willing to answer some surface questions about yourself and what the deals would look like, I could get you an idea. 

On the surface, the answer is obviously yes. 

For rentals I typically prefer going with LVP flooring, affordable cabinets etc. but one thing I like to spend $ on is countertop as its used often so I will go with an affordable solid surface top. 

Most of the ones we won worked out ok, but one wreaked so badly of cat urine even after stripping out all the soft surfaces we cut our losses and sold it to a handyman unfinished who wanted to live in it and refinish it himself.  

This helps address any issues immediately and keeps operations running smoothly.3) Attention to Detail: Beyond just surface cleaning, I look for cleaners who pay attention to the small details—things like checking for missing items, making sure coffee maker is clean, ensuring all amenities are stocked, and noticing any maintenance issues that might need attention.
