Otherwise, anytime someone puts a small hole in a wall a landlord could use that as an excuse to oust them.

Is it a hard-stop wall, no more, or just each additional over the 5 would incur some per-envelope fee? 

I look for opportunities to offer MORE for a tenant but I look for low hanging fruit in this regard.

There is a lot of moving parts to this story, so hang in there....I bought a house from auction to flip in Colusa County, California April of 2023.

People hanging outside? 

Hang in there, there are also wonderful perks to being a host!

I'm exploring all options at this point including finishing the home with other builders, as well as selling what has been built (slab and block walls of a single family home 4 bed 3 bath) to another builder or investor.Does anyone have any recommendations on where to look for potential buyers for something like this?

I did this exact thing last time a tenant asked to install a TV mount on the wall of a bedroom.

After moving out, we re-stained the front porch posts with a darker stain (photo is pre-stain), replaced the front door, did touch-up painting on walls and trim, installed new keyed-alike locks on front/back door, and installed a vented bathroom exhaust fan that wasn't there prior. 

Plan is to wall it off and convert to a 4br/2ba,  update existing bath and kitchen, new floors,  interior and exterior  paint.
