We bought a home in a great location with good bones, but every room, walls (99% had wallpaper), lights, outlets, switches, floor, doors, bathrooms, and kitchen needed help!  

With a finished basement, new kitchen, hardwood floors, new bathroom, etc.

Yes kitchen is one of the only areas that's not just floors and walls (and bathrooms).

An older semi retired journeyman contractor who thus far does great work and my $8.00 an hour felon who spent 30 minutes in the bathroom the other day and came out as high as a kite!

And what is the brand/name of tile in the bathroom?

There are still stickers on the toilet and sink in the bathroom. 

We have an opportunity to buy a recently renovated Tudor style home at $160,000 which we would personally live in (House Hack) with one move in ready basement apartment and a 5 car garage with a finished bathroom, which would cost roughly $15,000 to retro fit for a second rental space.

Since house 1, where I didn't, I have done this in all of my bathrooms, and dining rooms.

I have replaced a water heater, furnace, bathroom sink, gas range and I am having new doors installed.

For example, there is a property in Kalihi for $679,000 with three living areas, 5 bedroom and 3 bathrooms.
