Getting a degree is not totally necessary but one that can bring income is good like engineering or computer tech.

I can't speak for contractors, but as a DIYer, I know even the most basic kitchen renovation may end up costing me 10k if I were to do it myself. 2-3k for cabinets. 1k for plumbing and fixtures1k for electrical and fixtures2-3k for granite countertops1k for tiling/flooring1k for miscellaneous like painting, etc. 

New sewer, electrical, electrical panel, mini split, tankless water heater, plumbing, flooring, kitchen, bathrooms, turf, driveway, hardscape, etc.

@Ashish D.I quit my day job as an electrical engineer from buying tax liens and getting houses for cheap that I turned into rentals.

I cannot tell you after buying a property how many things come out of the woodwork like roof repairs, electrical repairs, new hot water heater etc. 

Expense your electric, water, sewer, internet, shovel, water hose, etc. 

Is this just a cosmetic rehab or are are there problems you have to fix in electrical, plumbing, utilities, etc?

Electric company put leans on the owner. 

I'm a land development civil engineer in the Austin area and love it over here.

Also for the area I reside in you don't even need a vehicle, you can walk to everything anyone could possibly think of and when I do need to go further I have my own electric scooter..
