Hell Ryan, I like your last name by the way, lolAs far I as I know the proper way to run wire is to fish it through the walls, maybe if your handy you can see what a electrician would charge just to run the wires if you supply the material ( make sure you have what's needed ) then you can install the fixtures and outlets.

Tile, paint, trim work, cabinet install, landscaping, etc...

If the option price has installment payments with the amounts credited to the sale price you have a financing arrangement.For all the thinkers out there, agreeing to a lower than market price after an option price has been paid without credits to the sale price is still a financing arrangement.

@Wendy Vaidic,If you install a shower, I would suggest that you include a "body spray."

My wife and I are also pretty handy with maintaining a house - we've done plenty of work on our own houses through the years, repairing sheet rock, installing microwaves and ceiling fans, etc, etc. and we are not afraid to look up how to on youtube.

You can probably get away with leaving it as-is and installing the new flooring on top unless the new flooring is also linoleum 

Most of the professional landlords I know wire for disposals, but do not install them. 

If you know who installed the system u may want to just call and ask them. 

nailed to the studs from the outside then brick installed outside that.

I am installing one right now @ $1200.
