I also dont texture the drywall, as patches are very noticeable from tenant dings, dents, nail holes, etc.As @Manolo D. eluded to, you would most likely choose different materials in order to reduce costs for the rental.You should also consider that your max LTV on the refi would be 75% if you dont take cash out, 70% on a cash out refi.

My perfect scenario would be if these could be patched up without the need for demo replacing with sheetrock.

Good Morning Dave, I got this good deal on 3 bedroom and 1 bath Brick home, huge backyard, nice hardwood floor now the good thingthe a/c unit gone, need little plumbing work, patch a couple hole in wall & paint.

Or suggest looking into service like Patch of Land, B2R, etc...?

Unless they rip it out of the wall when they leave there should only be 4-6 bolt size holes that patch easily.

The debt CF sites like Patch of Land and Peer Street offer shorter term loans you can put the money into, but bear in mind that your return is basically capped at the interest rate and you'll be paying taxes on interest income (but you'll pay taxes either way).  

I would call around with some electricians and get estimates but they will probably have to open up a lot of the walls and it could cost quite a bit to run the romex and boxes and then patch the walls back up, like 5 or 10 thousand but you may get lucky and find someone that will do it for cheaper.  

My son said, that the only things that needed doing was to repaint over some holes that the sister had patched.  

Get a $20-40 vanity light and patch the old hole with drywall.

I guess what I'm looking for is more ammo when telling the (former) tenants why I'm not going to patch the carpet.
