...the bathroom has tiles where the shower is, and the rest of the room is concrete, so im wondering on how to tackle it?
I would simply paint the concrete. It is no different to a unit where the bits that need to be tiled are tiled and the rest is painted. Check out my thread (link further down) about the unit my son did up. It is painted concrete walls throughout. He chose to tile some bathroom walls for aesthetic reasons, not because they needed to be tiled. See the photos and you'll see they were not tiled for the past 50 years.
whereas the kitchen, as you can see is L shaped, and im trying to work out how to get the $750-$1000 kitchen,
I would keep that kitchen and paint the cupboards inside and out. Pull up (or scrape up) the vinyl (?) flooring and/or tiles and polish the boards through the whole kitchen. Don't buy a dishwasher for the moment, get it rented and change the kitchen down the track. (Dishwasher will be deeper than those cupboards so will not fit if you keep them, which I would do for now.)
The last place we bought has that style of kitchen. We couldn't afford to replace it when we renovated before first tenants went in. We painted the kitchen and put timber laminate flooring on the benchtop with a timber strip. Looks so much better than it sounds . Has worn well.
We have just offered to replace the kitchen the the tenant who has just moved in. She said she would love to keep it (but understands if we change it) as it was one of the things she really liked about the house.
The good thing is that if you polish the kitchen floor too, when you remove this kitchen the new one will be wider and you will not be left with any unpolished bits (as long as you replace with a similar shape kitchen).
also, as you can see there are 2 types of tiles laid, which are horrible, I get the gut feeling that the green tiles have been laid directly onto concrete and there are no floorboards,
however the rest of the house is floorboards
Can you get under the house to see if the kitchen floor is concrete? If it is, in the thread about my son's unit, you can see the difference stick on vinyl tiles made to his kitchen. Cheap but effective (probably not the best over the tiles unless you fill up the grout lines, but there could be a difference in level between the tiles and the vinyl. Polished boards throughout would be my choice, easy, less expensive than doing a different floor in the kitchen too.
Painting the bathroom all white will make it seem larger and clean and fresh, new shower curtain can be changed for each new tenant.
The living room needs paint and floor polish and will look so much better with just that.
If this is in a cheaper area, that is all I would do.
