We've visited this area for over 30 years so I'm pretty familiar with the lay of the land.

I am thinking on changing lay out.

It is good that you have already made a point to lay those out, including having easy access and only keeping it there for 1-2 years. 

In a similar fashion I did some of the work, tiling painting, flooring cabinets etc. but also contracted a lot of the specialized stuff out. 

Ie tile tub surround, $/sf floor, high end vanity with stone top or builder grade with cultured marble? 

If you had $17 and the clothes on your back, I am willing to bet it wouldn't matter 1 drop what anyone said of how it "can't" be done, because failure is NOT an option at that point, the next meal depends on it, where you next lay your head depends on it, because you MUST find, make or build a way to how it can and does work.

Added a custom made tiled bench for the entry way and tiled the floor. 2 updated and upgraded bathrooms with main bathroom getting granite countertop.

New wood flooring and tile.

Not sure about the housing stock in your area, but in AZ, homes built in the last 30 years tend to have the least amount of work needed because they are built with stucco walls and concrete tile roofs that last a really long time.

Downstairs is all concrete floors so there would not be very much prep to lay down either laminate or LVP.
