We raised ceilings, removed walls for an open feel and made everything on top floor new again.

Otherwise you’ll wind up with unseen water penetration and all kinds of mold and nastiness within walls and other places you don’t have access to.

Our tenant just moived out and made several unauthorized changes to our house, including installing a Ring doorbell (which was removed, leaving two large holes drilled into the brick) and installing an outlet and ethernet connection on the wall above the fireplace (which he sighted as an improvement, but I'm not sure most renters will install a 40+ in mounted tv, making it an eyesore on the mantle wall in my opinion).

We went in with a laser tape and measured walls, cabinets and floors.

Surely your due diligence on this one will bring great equity w/all the newer updates.

True investors don't want you to waste their time and they want you to find them deals off-market.

For example, you buy the place and the tenant could claim the Seller allowed them to paint the walls black or that their security deposit was twice what the Seller claimed.

I would recommend getting a good mentor or listening to Craig proctor, and learning a script before calling people so you know how to talk and get to the info that is needed, so you aren't wasting your time!

Don't waste all your money on normal things. 

I am installing WiFi controllers for both thermostats so I can monitor and also purchase a cheap wall unit for their bedroom.
