Negotiated with seller directly, paid their closing cost of seller to seal deal.

you will need to plug any cracks or holes around the property and attic to make sure animals can't enter the building and you will need to deal (trap, kill etc) any rodents currently inside.within each unit you also need to seal any holes in the drywall they might be using to get in.

Spray-n-Pray (shotty workmanship and major issues covered with a coat of paint) is running rampant these days and we want to spec the work, INspect the work, and decide when the wall is sealed, the ditch filled and the work is complete.  

from my experience, its rarely a single mouse, poison outside the home and seal up the holes in the first and best step!

If so did you pull permits before work was done and did you have to leave the shower wall open for inspector to come by to approve before you could seal it up?

I have found that sealing from the interior alone will never stop the water from infiltrating.

We just bought our first home here July 2020 and I think seeing the appreciation on our home first planted the real estate investment seed.I am looking forward to reading everyone's post, adding to the post, and seeing what kind of creative ways everyone seals deals.

What is still sealed gets taken by me or left for the next tenants. 

You’ll always have moisture issues in basements unless you seal it, which is expensive.

We opened a doorway directly to the main room and sealed off the existing doorway for $2500 as I'm sure all tenants would prefer this layout.
